It could also be a stuck 1-2 valvetrain in the valve body. I had one apart(cast iron VB) and cleaned up the 1-2 shift valve train then added lubeguard red to new fluid and it was fixed. I seem to remember another one with an aluminum valve body that needed to be reamed and an oversized valve installed.

I took it apart and bad news for me.....

I dumped $50 into a new govenor and pulled the pan to find my tranny fluid was black and there was tons of clutch pieces in the bottom of the pan. Now on to finding a good cheap used 700R4

The 700R4 isn't the easiest Trans to start out with if you've never built one. I suggest investing in a Rebuild/Overhaul video and an ATSG Manual to help you along.
One tool that is needed is the rear clutch spring compressor tool and a good set of Lock-Ring pliers. Other things/tools can be used for most parts. Should replace all the Bushings, Trans Shop will do it fairly cheap.
