Ok...
My dad owns a 94 Oldsmobile Achieva (4-138 (2.3) MPFI) and he needs an automatic transmission. I checked on car-part.com and there is two possible for his car.
TH125
and 4T60E
The TH125 is it the same as the Fiero... if it is... I just thru mine in the garbage last week

and for the 4T60E is it the same as in the 3800 car?
Also, how to find out witch transmission he needs? will the vin code tell?
Thanks
