Well , changed the solenoids tonight , no difference , still no TC lockup. o/d works fine, have not gotten to try the manual lockup switch with the new solenoid yet because I took the switch back out and I am too grumpy to put it back in tonight and try that.


any more thoughts or suggestions? Anyone know how to test the brake switch and see if it went bad?

 

Me too...

Gonna have to get inside the pan. May as well freshen up everything as long as I'm in there.

 

when i bought this truck the TC wouldn't lock, had the trans shop put in new solonoids, and nothing, they had to change the VB to get it working, so with that in mind, im making a call to goerends tomorrow unless someone has a better idea for me....
