700R4 WOT throttle problem
Hi.
Some time ago I had an upshift sleeve installed in my trany. This was to allow the trany to shift at WOT from passing gear to OD.
The problem is the trany now shifts back and fourth at WOT.
Besides the sleeve, the trany has never had any work done to it and has allmost 100k miles on it.
Any ideas

I took the car out and ran it. Trany jumped up and back. Let up on the pedal tell it went back to OD. Foot back on the floor to WOT and it stayed in OD. got it to 135 mph then ran out of,traffic free, road.
Only change is the ported plenum.
It does pulls better at highter revs now.
