I got the truck back up and running, that ball bearing turbo spins FOREVER after shut down. Pretty awesome. But it was all short lived as the trans is now doing what it was before. I'm assuming because ambient temperatures are now higher than they were before when the trans had to warm up first.
So trans loses LU, then OD, then 3rd, then 2nd, as the trans temp rises. I'm assuming its because of the fluid thinning out at it gets warmer and leaking past a seal. I was thinking a servo at first, but that wouldn't explain losing all the gears the way it is. And last time I dropped the pan to try to figure this out, I took out the gov assembly and broke it down/reassembled it. That fixed it for a couple month. That leads me to believe it was an oring on the gov sensor/solenoid, or the gasket itself. One of the orings on the either the sensor or solenoid (can't remember, but it's the one that goes into the middle of the governor housing body) was very loose. That worried me, but it worked after I put it all back together so I didn't think about it again.
So my plan is to get new orings and gasket for the entire gov assembly/housing, and see if that works.
Does my logic make sense? Or could I be overlooking something simple? It has been a long day.
