Thinking about doing a shift kit what's the best? I have already gutted the drain back valve and installed a temp gauge in the hot line.
I'm thinking about GM solenoid and transducer as well have 83,500 mile on her now and need her to last. no sled pulling or hot ******* going on, just all around pulling farm equipment or play toy's (buggy's or boat).

 

I did a write up long ago about installing a Transgo kit. You'll have to search for it.... Well worth the effort to put one in!
