How to Install a TransGo TF-3 Manual Valve Body Kit in a A-904

Maybe you should wire that lever back. :)

Super easy. Takes like, 2 minutes under the car.
Or....You could mount a pull cable ( like a throttle lock cable on a 4WD) To adjust the Kickdown leaver in, out or somewhere in between. That way you can manually change the line pressure to soften the shifts around town and then firm them up when needed by simply pulling the handle ;)
You really need a pressure gauge to dial in the pressures to where you want them. I've got an electronic line pressure adjustment in the works at the moment.
