My 82 diesel Suburban's transmission died yesterday ... flakey behavior for a few days, and now it barely moves when the engine is revved.
It is a 6.2L K10 4x4, 3.73 rear, it looks like a 4 speed overdrive ( PRND123 ).
What type and year of used transmission should I be looking for to replace it? Would something other than an identical replacement be a better idea?
