But its interesting to note that there is a very low cover/piston failure rate for the 4L60-E TMBX converter. Production Began 2017 Electronic challenges exist when mixing and matching the 6L80 as they must be matched to their particular engine. The 6L80 / 6L90 uses three-way solenoids and variable bleed solenoids for improved shift quality. As such, Sonnax has a good view of both sides of the pump, so we are intimately involved with engineering solutions to both trending transmission AND converter issues. To achieve this flip-flopped damper orientation in the JMBX, the profile and shape of the piston is radically different from the TMBX. Helping transmission shops achievesuccessful and profitable operation. The bottom line: The very thin (.020") woven carbon friction material cant survive the way the JMBX piston applies. I use this vehicle to tow a 20 ft 10k trailer that I use to carry a 5500lb tractor. var d=new Date(); And Sonnax doesnt even offer a forged clutch piston for the TMBX there just isnt any demand for one.
