Interested to see what you find out. Good luck with the repair.
I am too, the truck acts so strangely. I took the line pressure booster off it today, the transmission started to shift so badly that they weren’t really shifts, it’s was just casual RPM movement. It eased itself out, and then all the sudden the clicking in 4th went away for the most part.. The 6th to 5th downshift is still missing, and the 25MPH thing is still there. But hey, atleast it’s kinda shifting well through the gears now.
The truck is starting to click in 5th and 6th, so there’s probably more carnage in the vb than i’m expecting. I can’t wait to rip it apart and see what i can find. Probably an implanted checkball and or a stick 6 to 5 downshift valve, massive piston bore scuffing, and a bad 4th valve which is what i’m expecting. Sounds like that’d be it too, if you decelerate and try to gain speed without fluid pressure, you’re gonna slip until it can gain enough pressure to master a downshift.
Still no metal in the pan, fluid is bright red, so atleast it’s not damaging the torque converter clutch, torque converter, or the clutches/planetary gears inside. But i truly can’t wait to get it fixed and have a truck that shifts like how it’s supposed to for a change.
Still no check engine lights or stored TCM codes, i’d expect atleast a solenoid to set a CEL if it’s slipping so badly in 5th, but i guess i’m wrong.
I will let everyone know the final results this week; whenever it comes in.
