tranny help

My 2M6, auto keeps stalling when I go to put it in gear. If I rev the shit out of it it will sometimes work but takes off right away. I was told it was something with the o/d.

I have found an 84 4cyl fiero. Is the tranny the same as my 2M6? Are there any other cars who would have tranny's that bolt up to my 2.8L?Same or different I don't care as long as it's not too much extra work.

Thanks

I'm assuming its an automatic. Sounds like the kickdown cable is causing issues. When the automatic shifts gears, theres a cable that slows the engine down making for a smoother shift.

Just do a search for cars with TH125 transmissions, there are a plethora of them out there.

I did some more searching and I think it might be my ttc that is causing my troubles. Does anybody know what the difference is between a th125 and a th125c tranny? Some sites say the fiero has a th125 and some say th125... Are there other tranny's that will directly bolt up to the 2.8L, possibly better than the 2.8L? (just curiouse)

Thanks for your help

The issue could be your torque converter clutch is locked on and won't disengage. This means reaplacing the entire torque converter, but you won't need to replace the transaxle itself.

Your Fiero probably has a TH125c but could also have a TH200c. Look under the hood (by hood I mean in the front of the car, where the engine is NOT located) at the driver's side inner fender. Here you'll find the Service Parts Identification label. If you find the code MD9, you have a th125c, if you find MV9, you have a th200c. If you find MX1, you're out of luck because I have no clue which one it is.

Some drop the c and just say 125, but they're still talking about the same transaxle.

The TH440-T4 is a 4 speed overdrive transaxle that will fit the 2.8, and is a worthy upgrade. This transaxle was later renamed the TH 4T60 in the 90's, but remained , for the most part, the same.

The 4t60-E Introduced in 1995 is computer controlled (the "E" is for electronic valve body) and should be avoided.

the TH125 is a 3-speed unit, there is no OD
