Don't think any of those old trannies would hold up to the torque of a diesel in today's pickups...I believe all of them are now rated over 1000 lb-ft of torque. If I remember correctly the new Superduty is at 1200 lb-ft of torque. I think the GM Turbo 400 you mentioned was supposed to be the strongest of them all back then - but it is rated to handle only 450 lb-ft of torque.25 years ago transmissions were better. Think about a C-6 ford or the GM TH 350-400. As long as you changed the juice every 70k+/- they would last forever.
As I type this I'm thinking about today's HP also.....
never mind, maybe.![]()
