Did you get a new or a reman VB
? If you got a reman could be the process missed something inside the VB
and youíre still leaking on your OD circuit. If you havenít torn it down, see if you can determine what temperature the fluid reads when it stops shifting normally 1-6. If itís doing it all the time thatís probably either clutch pack or wiring - more likely clutches though. If itís only doing it at higher temps, itís probably a leaking solenoid piston or bore in the VB
Iíve done a lot of back and forth with revmax, PATC, and suncoast the last couple months trying to diagnose mine. Itíll shift fine 1-6 as long as Iím below 10% load AND below 130* fluid temp on a bone stock, never serviced AFAIK
, 175k mile trans with a revmax TCM. Itíll shift normally 1-5 (limited via ERS) as long as Iím below 20% load regardless of fluid temp. Fluid still bright red with zero burn smell. Iím still pretty sure my OD clutches are shot but the general consensus seems to be the main problem is a worn bore, cracked piston, or split o-ring on one of the solenoids in my VB
Not saying all reman parts are junk but having seen brand new stuff bad right out of the box (sensors, OEM ball joints) it wouldnít surprise me if a reman brand missed a very minor internal fault during QC inspection which led to a recurring problem.
Hope this is at least mildly helpful...
