Re: 700r4 Overdrive Problem
Your system runs on both the ECM and Vaccuum Pressure, if I'm not mistaken
It will kick out of over-drive and lock-up when the engine is under load
It will only stay in over-drive under easy-load situations, mostly, on flat stretches
Changing the fluids will not help
What year is your buggy?
It's a donor drivetrain lookin' for a 'Vert
