Re: t56 swap list, everything you need to know!

im looking for information on all the parts required to do this swap. i have read the thread and still would like to know some answers to questions from my previous post.

it does not seem like this is a very popular swap. and it might not be what im looking for because in the dirt im not going to need 6 speeds. My trruck is 180 degrees different from what the majority on this site use there trucks for. I am looking for reliability, strength, and something that is manual. I might end up going with a turbo 400 with a reverse manual valve body if the price is right. I did not want to go the auto tranny route cause of the cost of tranny coolers.

Re: t56 swap list, everything you need to know!

a T56 is strong, reliable, and is a manual.

Greg you are planning on using it 2WD right?

2wd yes, gonna be using it for desert racing. and prerunning things like the baja 1000. the t56 is all the things I am looking for but the swap looks like its going to be quite expensive and parts avalaibility seem to be few and far between. thats not a good combination in the middle of mexico, that is why i am looking at the turbo 400 set up now as well.

Re: t56 swap list, everything you need to know!

I wouldn't think desert racing and an automatic would go good together? (heat issues)

for that kinda of racing I think you would be better off looking at a racing designed manual (IE something with straightcut gears in it)

why not just run an oldschool 4 speed? and gear your rear accordinlgy? btw if you were worried about inital cost and work why are you building a race truck for desert racing?

recomend a keisler 5-speed. Easier for clutch selection.

its not the intial cost its the cost of something htat seems to be VERY limited on extra or repair parts. Cost is a factor but not a major one. Im not rich so a budjet build is what I am doing. I plan on racing once or twice a season most of the time It will be a dune and desert truck.

Everyone runs the turbo 400 in the desert. there are very limited numbers running the manual transmissions let alone a t56. as long as you run a good set of coolers there is usually not a problem.

Re: t56 swap list, everything you need to know!

and it can also be found by searching. I am pretty sure you could find the answers online just as fast as you would be waiting for a reply.

Re: t56 swap list, everything you need to know!

probably could if I knew what the hell i was looking for. I do not think i am doing this swap after all though. form reading the information in this thread it seems parts are notthat easy to get and ill need to make a custom spacer. The t 400 will work just fine for my application so Ill be doing that.

30 second google search...

Quote:
1993 to 1997 LT1 F-body T56
Same length as T5 and 700R4, so you can re-use your same 27 spline driveshaft, torque arm, and bushings
Electric 40 pulse per driveshaft rotation VSS (Vehicle Speed Sensor)
LT1 pull-style clutch, bellhousing, and slave cylinder is necessary

1998+ LS1 F-body T56
This is from the LS1 f-body, so it has a different length input shaft, and a completely different push-style clutch setup. The throwout bearing is a hydraulic unit that eliminates the clutch fork. To change this transmission to work with the LT1 clutch and bellhousing, you will need to replace the input shaft as well as the front cover of the transmission case (because it does not have the clutch fork pivot). An LS1 master cylinder might be necessary. The case and tailhousing dimensions are identical to the LT1 T56.

Retrofit T56
The major benefit to the Retrofit T56 is that it allows you to use a standard style clutch and bellhousing. It also has a mechanical speedometer sender which is similar to the 700R4 & T5 transmission (an electric 700R4 & T5 VSS will bolt right in). The draw backs are that the transmission is 1.9" longer, so the driveshaft and torque arm must be shortened. It is available new from Tom Sallee at Sallee Chevrolet for $2295.
So now you can quit your bitchin' and thread whorin'.

-Is the T56 shift handle even tall enough to work in the 5 speed center consoles?

Hopefully that works ^^

Anyway, I just smoked the tranny in my '01 2wd and the cash is pretty much a wash....and I'm all excited that I have the same center console/ shifter placement as this Blazer. Anybody know if the motor in this truck sits farther back than the 4.3??

Re: t56 swap list, everything you need to know!

I've got most my 1997 4.3 auto to t56 swap planned out with this thread and others, however, there are a couple things I have not found any info on. First is the PCM. How bad is it going to freak out when my 4l60E get unplugged? I assume a re-flash is in my future as well. Next, mine is an extended cab with the 2 piece drive shaft \ carrier bearings. I would LOVE to eliminate this drive shaft and go to a one piece, maybe one of the aluminum ones out of the 4wd's? Does the length increase of the t56 help any here?

Re: t56 swap list, everything you need to know!

For the clutch line you can use these to convert the quick disconnect to a 3AN fitting and then run a 3AN stainless steel brake line for the clutch line. I ordered it all from jegs because summit wasn't going to be able to ship my line to later and cost with shipping was $61.

i had one made at a local hydraulic shop for half the price.

plus i have a feeling your going to ahve interferecen issues with the master cylinder line and headers if you run that setup. i have less then a 1/4" of clearence with a 90* fitting on my master cylinder end

Re: t56 swap list, everything you need to know!

The T-56 to 40 tooth reluctor ring prototype that I made from tippmann's box of reluctor parts fits on the output shaft just fine. It is a bit tight but not any worse than the original ring was. The VSS contacts the ring a little now thanks to the larger diameter of the 40 tooth. We will need to experim
