My 96 beretta has a 4t60e, it blew the right side diff right out of the trani. i need to what tranis that i can put back in it. i kind of dont want another 4t60e because my car only had 58000 miles and that happened. also there is one at the junk yard with the same problem. but the older, 93 and lower, 3speed tranis have the same gear ratios and so far i havent seen one break. my old beretta had 189000 miles, and i race it every week at the track, the trani never once messed up. so i need to know if i can put one of these in and what i have to do to make the sensor work with my 96 ecu.

only reason diffs blow the pin out is from abuse. spinning the tires on a fwd, no matter what trans or make it is will all have the same result.
your transmission should be reparable without removing it. there are 4 bolts and the diff cover comes off. you will need to get another complete diff assembly and the cover, either from a junkyard or from a transmission shop/parts supplier. i have changed these diffs in less than an hour. i would also recomend pulling the pan off and cleaning the metal shavings out and changing the filter. most of the time the metal just falls into the pan and doesnt do any damage to the rest of the transmissions. would be the easyest and moct cost effective way to fix it.

Yeah for only 58k your transmission should be fine. That's a bad failure and I agree it's probably from one wheel burn outs. I have 200k on my 4t60-e and it runs like a champ. Only work I've ever done to fix a problem was put in the GM seal conditioner.sigpic

no you obviously mis understood me. the dif blew out of the trani and was laying on the ground. when this happened the cap busted and took a chunk of the trani wiht it. when it took a chunk iof the trani it also crack the whole side of the trani itself. no way to fix it. also ive never seen a 3spd auto do this. like i said i had one with 189000 miles and i ran it at the track all the time, inclding one whell burnouts. the trani dosent make a sound and still works great to this day. What i want to know is what i have to mod to put one of the 3spds in a 96 on a 3100. i know they bolt up but the sensors are different. the one sensor is for the torque converter oand wont serve a problem. the other goes to the gear selector and senses if the car is in park or neutral. i was just wondering if anyone knows what i gotta do to make this work. ive never seen a broken 3spd, ive broke a 4t60e and saw em.

Putting a 3spd in a 96 will be a MAJOR project. I don't know if the 3speed is electronically controlled or not. If it's not then it may just require swaping then getting a DHP to delete all the trans control stuff out of the ECM. ODBII is what your 96 is and will throw tons of codes and may even run in limp mode when it doesn't get info from the electronically controled 4t60-e.
If the 3spd is partailly electronically controled then I have no idea if it will be compatible with ODBII ECM. If not then you're looking at engine bay wiring harness swap and ECM swap back to ODBI and converting to MFPI instead of SFI. Sounds like a headache to me. You may even have to swap dash harness and gauges but I'm not sure how the interface to the gauges changed when it went to ODBII.
I've heard of plenty of 3speeds going, (slipping) as the torque rating is way lower than the 4t60-e. And you'll get a lot worse mileage due to lack of OD gear. Instead of running at 2000 RPM at 70mph, it will be 3000 RPM!!!
I guess it really just depends on luck of the draw sometimes too on trans lasting...
5speed swap would be the best route if you are going to change from the factory trans. It requires some work but is the best durable trans you can bolt to these cars.sigpic New 2010 project (click image)

the 3spd is not electronically controlled. i unplugged all of the sensors on it and ran it in my old beretta. the only problem is that the gear sensor thinks that its in gear and it wont start. but if you start it then unplug it its fine.

i would just put in another 4t60e your best bet would be to rebulid a 4t60e
and put that in your car usualy they last a long time mine had 130 k on it be for i rebulit it and i beat the piss out of my car a tranny with 105k on it could also be ready to go out now that my tranny is rebulit i also can take off better then i have in 3 years no slipigeComment
