Any one can do transmission work.

Thirty+ years ago I had a cherry Olds '63 F-85 Cutlass (it's purchase for $150 was a lesson in how stealerships work) with the 215 aluminum block V-8 (later used by Rover) and a transmissions from hell (it didn't have a torque converter). Specific only to the '61 to '63 Olds F-85, GM quit providing parts around 1965 for the transmission.

Five years and 40,000 miles after the purchase the tranny acted up.

I bought a non-working F-85 transmission for $10, about the value of the aluminum case and swaped out parts until it worked. When you are 24 in grad school, time is costless.

Considering how totally ignorant I was at the time (not claiming I'm less ignorant now), it proves anyone can rebuild a transmission.

The car went out of my life in 1984 when my ex-wife1 took it to work against my protest about projected hail storms. Instead of hail, the car got hit by a tornado. It ripped the hood off, breaking the windshield, creasing the roof, and taking out the hinge mounting area of the body.
