Got an automatic 91 f350 (460) that needs a new t case. Wondering if a 7th or ninth gen might be interchangeable? Or maybe any f250s?

 

Sometimes it is cheaper to repair the original problem than to install another unit that could have bigger problems.

Can we ask what appears to be the problem with the present unit ? Some problems can be corrected without removing the unit..

 

Previous owner left hubs locked and the case is split in half

 

Have you tried any salvage yards ?
