Auto to Manumatic Trans??

I am totally new here and got my hands on a nice 87 S10. But it has a auto trans which is 'ok', but is there a way to make it manumatic without having to to a lot of modding. I don't mind modding but if its going to be a ton of work i will just swap the trans out with a manual and be done with it. Let me you opinion, Thanks.

I had to google what a manumatic is, so for anyone else wondering like I was, it is an automatic trans with a manual shifting gate that works sort of like a sequential manual trans, bump it forward and back to shift one gear at a time and more importantly, hold that gear till its changed.

that type of trans is really just a fancy shifting program in an electronically controlled transmission, popular in the 00s and 10s. I cant think of a rwd application that has been made that fits any motor in an 87 s10 (Iron duke? 2.8? 4.3?), the only car that would have had something like that is the camaro/firebird and I dont remember a trans like that. your 87 is a mechanical trans, operating on vacuum and cable, so you cant add the programming.

there are sequential manual transmissions that are manual transmissions with servos and electronic dual clutches, even more complicated. again, I cant think of an application besides the corvette, which wouldnt swap over anyway, or the newest camaros. a quick search shows a Gear Vendor application to turn a GM 4 speed electronic trans into a manumatic. sounds cheap haha.

long story short, I dont think it has been done and I think it would be very difficult to do, just because they never made that trans for a rwd application or if they did it would be cheaper just to buy and drive the car it came in.

Re: Auto to Manumatic Trans??

Ok, thanks for the info. Haven't looked at the trans yet. (Yes i am new to cars) but my trans would have a little lever connected to a control cable? So in theory i could put in a ratchet shifter? I don't mind the auto trans but would like to control over shifting in someway.

Re: Auto to Manumatic Trans??

yep, a floor shifter would install easily. should be a 700r4 4 speed in an 87

It acctually has a floor shifter init already. But even replacing that with something like a ratchet-shifter doesn't give me manual gear control does it?

Re: Auto to Manumatic Trans??

well, a ratchet lets you go up the gears in positive steps and holds the gear you are in, a floor shifter should do the same but the danger is popping into neutral or reverse with a standard floor shifter. a ratchet has a lock out.

Re: Auto to Manumatic Trans??

Trying to be honestly helpful here.
Since you don't have a clue on how to do any of this your best bet would be take it to a reputable speed shop in your area and have them explain the possible options for a shifter to fit your 30 year old transmission and have them install what you decide on.
By the way "just swap the trans out with a manual and be done with it" isn't all that simple either. Takes a lot of no longer easy to find parts, a well equipped shop, experience, and time to complete. Oh, and money.
