where can i find out which auto trans and what size rear end my car has?
this is something i have been wondering about, but all i get online is replacement part results.
 
This link has the most comprehensive information I've found online about Torqueflite transmissions.

For the rear end, measure the axle tube diameter. If it is less than 3", you have a 7-1/4". If it is 3", and there is a cover on the back of the differential housing, then it is a 8-1/4". If the is no cover on the back of the diff housing, then it is a 8-3/4".
 
You should be a 904 trans unless someone changed it. The rear is either going to be an 8-1/4 or a 7-1/4. If you sneeze at the rear and it breaks its a 7-1/4.
 
i romp on it pretty good sometimes, and all i get is a roar, sometimes squealing tires, but never a broken ***...
so i guess its not a 7 1/4...
and im pretty sure it is all original, the guy i bought it from didnt tell me he had a new one put in, and he bought it from a kid who's grandma had died and he was just trying to get rid of it, so i think im 3rd owner...
 
Its most likly a 904 trans and ether a 7 1/4 ora 8 1/4,youd be surprized the 7 1/4 can hold its own mine did pretty good in my car i never broke it but ya my gears where only 2.73's so that didnt help the hurt and the tire was only like 4 inchs wide :scratch:
