4l60e Problems and Solutions

[Deeze49686]

you sprag shit the biscuit. it flipped, and broke the cage, but sometimes you can make it flip back over, thats why the death rattle in 2nd and 3rd.

[livehard365]

at the end of my trannt saga the junkyard was unable to rebuild my tranny for a reasonable price ($1200) so they are going to refund my money, but another problem has arisen I think i spun a rod bearing. It sounds like a midget with a hammer at idle but it goes away when i am driving. i was hoping (but i am sure it is unlikely) that this is a tranny issue, if not i'm sending the truck up river.

[Deeze49686]

what, 1200 for a junkyard to fix a tranny? i dont even charge that much to do it right........................

[6 feet under]

I have a 99 sonoma 2.2 4banger. My tranny does the slip & studder in 1st and reverse when cold. I have a leak somewhere in front of the tranny pan. My floor jack broke today. Jusk a borken jack, no injurys, no damage. So I am having a hard time seeing the exact source. A few people i have spoke with have said it could be the torque converter. That sounds reasonable to me. What are your thoughts? Know anywhere to get a good converter? What should the ballpark cost to have one installed?

[Deeze49686]

i can get you one cheap, delivered right to your door. PM ME.

I have a 96 4X4 blazer that is having an issue. I just got it so I dont know much about its history, just what its doing now. Its a 4L60E that does not upshift unless you get speed up and then let off the throttle. Then it will shift. Seems to down shift fine though. It is also making a grinding noise in "D". No noises in any other gear. If you just put it in Overdrive it seems to work fine with no noises in any gear and seems to go through all gears, just doesnt like to up shift. The shifting was making me think of the TPS, but Im not sure about the Grinding.

[unclejames1]

ok I have a 94' 4.3L 4l60E im guessing. I left it sit for about 3 to 4 weeks and now my speedo doesnt work anymore and just wont shift out of 1st unless you manually shift it from the column and then will only go into 2nd! So I thought it was the vss so I went to the local junkyard and go one out of an Astro van. But when I put it in the truck when I got home It didnt seat down flush like it was when I took the old vss out. It sticks out mabey an 1/8'' from being flush. So I went ahead and plugged it in and took it down the road and still no change!

could it be the vss I got from the Astro van doesnt match up to my truck?

[Arealcwby1]

Ok I hear alot of problems and some are close but ima tell mine as well.
My 2000 2.2 4 banger will drive great from a cold start for anywhere from 5-10 minutes. Then it seems to throw its self in nuetral, now i can stop and shift to first and then shift to second but thats all it will do. I think the speedo dont work either dont really recall.

Now if I kill the truck for couple minutes then i can start it up and take off in drive and get from 3-10 minutes drive time again. Talked to a gm mechanic and he seem s to think its the 2-3 solenoid , and another tells me he thinks filter is clogged.

But prior to this problem i was cruisen the highway bout half inch of ground and hit a big chain (BIG CHAIN!) Dented tram pan up quite a bit . took pan off got new one and looked ok inside. I do seem to have a solenoid that feels looser than the others, gonna replace it and try that. But had a friend have same issue with tahoe and said he change a slim peice that was connected to wires int the pan that has lots of holes in it , not sure what the parts call but its in your face when you take the pan off.

Anyways anyone have any suggestion?????? I need help. Thanks for taking time to read all this crap,

I have the same prob. but my speedo does work?

[Starbird]

have a '99 Blazer 2WD, and a '02 Blazer xTreme. My question is this; The '99 (83K miles) shifts very normally. The '02 (73K miles) shifts like it is in tow-haul mode, even though there is no option to switch as the full size trucks have. I bought the vehicle used with 60k on it, and it came with a factory tow package. The shifts are a bit firmer, and at a slightly higher RPM. There are no other issues with the tranny. The dealer flashed the ECM, and stated that the download from GM was based on the VIN number of the vehicle.

Is there a problem I am facing, or is the programming "sportier" for the xTreme to go along with the suspension mods?

thanks,

Jim

[King_Ice_Flash2]

Either someone put a shift kit in it, or something is wrong with it. The Xtreme uses the same engine/transmission/tuning as the factory S10 Pickup/Blazer.

[Dockboy19]

OK new to the S10 forum, I have played around with Mustangs for a while now and wanted a winter project. Found a 94 S10 and the truck is in good shape for being in the NE all its life. I have problem #1 reverse is weak but goes at idle. If I give it any gas it makes a grumbling sound. I don't see anyone really asking about that one here. Is it worth trying to have it fixed? Or should i just try and fine a used or rebuilt one?

thanks,
Jake

[Deeze49686]

if you dont fix it, ill buy thhe core. i dont have a 94 at all anymore. keep me posted.

[97deluxeny]

what if your driving down the road on the gas and it wont shift until you let off the gas, but it dosent go into second it goes into third then after that it shifts into 4th fine but then overdrive dosent work. it turns 3k plus at 65. and on top off all that reverse dosent work.

can someone break it down for me please.

[Deeze49686]

you have no 2nd, no 4th? you have reverse? if you have reverse, the 2/4 band is broken, not applying, or burnt to a crisp.


pm me for more options............

[NCRides]

OK my daily driver shifts fine and has good power off the line but when cruising from 35-70 it lacks power to accelerate, you roll the throttle till it down shifts then you are going too fast so you back off the throttle and it goes back into lockup and lugs. Below 35 and above 70 it has good throttle response and takes very little throttle to feel acceleration, but in the mid range it feels like I'm dragging an anchor

[mpcranbox]

I have no 1st and 4th gear. check engine light on with codes like tcc malfunction, shift solenoid circuit electrical a, and shift solenoid circuit electrical b, malfunction. changed fluid and filter plus replaced one of the solenoids. Both worked fine when testing on the battery made and audible click. the trans fuse is fine and i am at a loss from here any help yall can give will be great! Thanks in advance!
Happy Holidays

[Deeze49686]

what kinda truck is it?

[sdime13]

i have a 94 sonoma with a tbi 350 from a 91 silverado, i kept the 4.3 harness and tranny, which im guessing is a 4l60e well anyway 1st and 2nd is fine but it never shifts into 3rd not even manually . i cant sseem to figure out what it is it just goes from second and feels like it goes into nuetral if anyone can help i would appreciate it thanks

[Deeze49686]

3/4 clutches look like my sister in laws chicken.

[mpcranbox]

it is a 97 chevy s10 2wd with the 4.3l

[Deeze49686]

howd ya get the pan off it?

[TooCoolCrewCab]

I have a 2002 S-10 V6 4wd. 65.000 miles. I’m a maintenance freak Mobile 1 engine oil every 3K, two trans filter changes and one dealer flush, lots of preventative maintenance. In the past week I have had a pump whine three times, first was after driving 15 minutes, it did it for two blocks then stopped. Next day it did it after 15 minutes then continued longer 10 minutes the went away. The next day I drove it to work 2.5 miles, home for lunch, back to work etc 2.5 miles. Worked fine no sounds but short trips. Tuesday was fine to work and home, that night I took my wife to pick her car up at the shop (bad week) 8 miles (15 minutes) to the shop perfect, then I almost made it home without the whine, then it started and wouldn’t go away after some more driving (15 minutes). Shifts seemed at the same time and firmness as usual. I checked the fluid level, it was a bit over the full mark, pulled it out with the whine and parked it accepting that it will need to go to the shop next. I drove it to work yesterday, cold, worked fine. Later I was asked to go to the grocery store, I didn’t want to break it before getting it to the shop. I drove it 10 minutes, 15 – 30, no sound what gives? I forgot something…back to the store, now we are at 60 minutes run time and no sound. I pulled it in the garage and sucked some pink fluid out to bring the level down to where it should be. Only sound was a funny faint whistle at the front of the trans that I first heard a week ago at idle in neutral and drive. Drove it to the shop today (15 minutes) warmer out today 44 degrees. No sound not even the faint whistle. Drove some more (total 30 minutes) no whine, faint whistle comes and goes, you can only hear it when you open the door and listen. This is driving me nuts. I feel I can’t rely on it and the shop will have a hard time believing me it ever made a pump whine. After reading the information here today it looks like there can be many components to check from the PSC to the inline filters, pan residue may point to something. My fear is they won’t find anything, but the faint whistle should be something.

[Deeze49686]

sounds like the teflon wore off your pump bushing. they wear off, and make a funny little buzzin sound, then when you put it in gear, the pressure goes up, and the convertor is pushed forward slightly, and then no noise. its temperature tempermental as hell too.

What do you think caused the whine, particles, dirt?

[Deeze49686]

lack of lubrication............

[johnny 5]

8. 1st and 3rd only, no 2,4 or R; sunshell is fractured or splines are sheared off. R&R. Try not to run or drive the car or further damage could result.

So, my brother in law's 02 4x4 sonoma lost 2nd gear and reverse. There's a nice whine comming from the case.

I was able to force the trans to shift from 1st to 3rd and 4th using my HPtuners.

I'm I correct to assume this thing is trashed?

[johnny 5]

should add, it's the 4.3 with 71k, all stock.

meanwhile my 575hp ls1 gto with the same 4l60e is thumpin along just fine ;D

[TooCoolCrewCab]

Shop dropped the pan, it is clean inside and no parts. must have been something stuck or a speck of dirt? The truck gets driven gently, maybe I should run it harder. My trip to work is only 2.5 miles each way, I go home for lunch. some weeks I never run it more than 10 mile stretches.
Could moisture build up from all those short trips?
Fluid almost never gets to temp in all those runs.

[TooCoolCrewCab]

Nevermind I traded it in on a Tahoe yesterday

[rocpede4x4]

i have a 02 2wd blazer with 93,000 miles. i but 2500 to 3000 a month for work. 1st and revsere slips and studders, then sometimes it will slip thru all the gears after it warms up to temp. and it reallys slips when i'm trying to pass a car, any would be good and thank u.

rich

[cwinnik43]

how about this, i have a 94 s10 blazer 4x4 with a little over 100,000 miles on it, first the odomiter broke, after about a month i randomly lost second gear but everything else works fine untill last week. now i only have first and second gear and it takes until i get to 35 to shift into second. at about 90,000 miles i flushed the tranny and putta new filter in and it ran great. this all really started happening after i got my pinion gear replaced. any help is VERY much appreciated.

[tretiak]

my trans drives fine untill 3k RPM and then slips under any throttle position

[solidchaos73]

Well last week i had my valve body replaced, and today coming off the high way there was a loud thump, then a grinding noise, then no movement at all. I stopped(obviously), put it down in 1..no movement,2 no movement, 3...movement. And Drive i get movement but it shifts at 5500 rpms(i have a 99 4 banger by the way). No reverse either. I hope its just something in the valve body, and the worst part about it is i cant do anything untill monday cuz the tranny shop i bought it at is closed on the ****ing weekends. THIS SUCKS!

[Deeze49686]

does it move forward in the od position?

[solidchaos73]

yes

[dphillips]

This seems to be my problem. 97 suburban 160k. So i guess the only hope is a new trans huh?

nah, just a rebuild

[boxbodyblazer]

Will a rebuild solve #25 (leak from front seal)?How long can the truck be safely driven?

[MiamiZQ8]

I have a 2003 Chevy S-Dime with a 4.3. One night I was pulling out of my driveway and I put it in reverse and it felt like I put the truck in nuetral even though the shifter said rev. So I revved up the truck and the truck didnt move so I put the truck in P and I waited 5 seconds and then I put the truck in Rev. and it went in reverse. This also happened on my mom's tahoe. What do you guys think the problem is? could it have just been a fluke?

No thats no fluke its a sign that somethings not right. At least get it flushed at a tranny shop and its a good idea to have then give it a check up. Its a lot cheaper then a new trans if it goes out.

[gillzs10]

how do i know if i have the 4l60e?
and where can you get a TPS, what is the usual price and how hard is the install?
I have a 97 4.3 ls 4x4 that sometimes shifts hard between 1st and 2nd gear

[gonzo/v8sonoma]

got quick quest. I have a 97 4x4blazer 4.3 atuomatic, dont no wat the tranny is. but truck is really slugish i think tranny but idk, while manual shifting; 1st gose great but skips 2nd, shifts at 3rd but dosnt shift wen put in OD and the whole time truck realy slugish cant figure it out; Would that be a tranny problem or engine problem? Oh and reveres works great its the the strongest gear

if anyone has any thoughts it would save me from an overdrawn headace THANKS!!!!

[ww228king]

Looked and looked, but don't quite see my problem on the list...
1998 4x4 S10 183,000 miles
Reverse is good
1-2 shifts good
2-3 shifts ok, but revs a little high
3-D wants to rev and act like it is slipping unless going down hill or on good flat land...but if you give it too much gas it will fall out like i put it in neutral and rev to the moon and if i let back out of the gas, it will catch 3rd then try to go back and forth between 3 and D

None of the gears shift hard and never have. It seemed like all this started all at once, but not sure. The truck sits in the yard alot... 2 to 3 months at a time sometimes...

[Zr2Waterfowler612]

I have a 99 Chevy S10 Zr2 4.3 with 171,000. It runs good (no Misfires) I go to drive and it gets to what seems like 3rd gear and O.D and it won't engage. But in the last 2 days of trying to sell it i have takin a couple people for test drives and it has shifted just fine off the bat (what seems to be perfect) and then after a mile of driving it shifts or slips back out and high revs.. Runs like 45mph at 3,000 miles. What could be the problem?? And is it easy and cheap to fix??

[Guamsailor]

Hello, ive got a 2002 zr2 4x4 and my truck was sluggish off the line like the parking brake was on. After it got warm it was ok but still a little sluggish. It also would downshift out of od so I drove it in third for a while and now it just revs in 3rd. Sometimes in reverse it stutters but not always. service engine light is on. Is the transmission shot or is there a fix?

I ended up taking it to a local trans shop and they found that it was a broken wire from the vss to the back of the speedo. it was behind the dash somewhere. grrr....... but i finally have it back on the road!!!!! WOOHOO!

[Blue2.2-X]

I started up my truck this morning (2.2 auto)and let it idle to warm up a bit. Put it in reverse and tried to back up and got this grinding sound and then a whine, truck didn't move. Let off the gas and the truck just rolled forward while still in reverse (not on an incline). I immediately shut off the motor. Because of where I am parked, I couldn't try forward gears. Snapped output shaft?

[levya]

OK I'm gonna mix issues in the remote chance the tranny issue is still diagnosable. 1996 4.3L "W" engn 218K miles. Original engine and auto tranny. Tranny serviced regularly (every 30K miles) and flushed with new filter, gasket, at 215K miles (early Dec 08).

I've been having misfire promblems that have resulted in twice replaced ignition cables, once replace plugs, and thrice replaced cap/rotor. It's misfiring again and fuel efficiency is down 30% (17mpg to 12mpg). Currently idles high 1100rpm at cold start even though it's not been especially cold here lately...mid30's lo40's overnight. Engine flutters under moderate acceleration in the 2500rpm range. A stomp to over 3000 smooths it out.

Lately I've noticed intermittent slow engage into R or 1st when truck sits overnight. I've also noticed rough 1->2 shifts and 2->3 shifts that sometimes seem tied to misfires. Something else I noticed. I brake to 10mph to make a hard 90 degree turn on a narrow street and if there's no oncoming traffic I tend to hit gas mid turn and there's a noticeable lag in re-engaging tranny as engine revs. And yesterday something new happened.

First start of day, I didn't let engine warm up long (temp in 40s) and within 1/4 mile of trip I turn onto country road with steep, twisty incline. I've got moderate acceleration 3200rpm or so and its climbing nicely in 2nd gear. Just when it's building revs for a shift, it disengages from 2nd and revs while taking a what must have been a hair over 1 second to find 3rd. Yeah, 1 second doesn't seem long in a lifetime, but in tranny gear switching time, it seems like an eternity.

Obviously, this new "symptom" could be caused by same problem that causes slow re-engage after a braked severe turn, but I hadn't noticed the problem under constant throttle before.

I thought maybe the tranny fluid was low, but a cold level check showed it was fine and I haven't don't a warm level test yet.

Any ideas?

[Dippis]

I have a -98 s10 4x4 truck.
It works in 1, 2 and R. In 3rd and D it just revs but doesn´t pull.
The oil looks fine.

It started with the car just stopped pulling when I used it in D and 4x4-high, if I pushed the 2wd button and then pushed the 4wd button again it popped back in to gear again with a bang! A few days later it stopped pulling on all gears except 1st. And now it runs on 1st, 2nd and R. Nohing else works.

No enginelights has come up, and the speedometer works.

It´s not the speedsensor on the tranny huh?

I hope I got my message trough since I´m swedish..
