i thought it looked kind of weird, some of the internals had surface rust on them. the "mechanic" that installed it said it was a "good" transmission

That is prob why it died, that will eat your trans up quick. You can always get another and do a rebuild and it will prob hold up fine

Your probably right, do you think it would be a lot of work to convert it from a manual to a automatic?

Do you still have the original saginaw? If you do, Why not swap the input shaft/bearing (if it's the same model) and get that thing up and running again? Shouldnt be too difficult to do. Clean the "new" housing out, pull the "old" input shaft and bearing and change them out. But one other word. The back end of that input shaft should contain some roller bearings. pack them good with some wheel bearing grease.

Crossmember will prob have to be moved. Which IMO is the biggest pain on these trucks as they never line up to any hole once taken off. Clutch and brake pedal assembly have to be changed and you need to wire up the vacuum switches for the lock up converter. Driveshaft may or not have to be swapped or changed. You will need to unbolt the the flywheel and add a flex plate

Def not a day project

So both transmissions failed cuz the oil looked weird and the internals had surface rust? Did you/they put new oil in when they installed it? Just seems odd that weird oil would cause 2 transmissions to fail....
