Old guy here too, and I'm here to tell you it's sketchy AF. I've been around engines and transmissions my whole life, and I've seen what a transmission looks like inside when you ignore it for 100K miles. It's not pretty.
As wonderful as those pairings would be, this sentiment about sums up my thoughts on the likelihood of them coming to fruition.
Right on Michael. I honestly believe all these bologna extended service intervals the manufacturers and oil bottles/flters are suggesting is an EPA thing.
Either that or these service depts are so busy fixing engineering blunders that they just don't have the time to service vehicles on a more timely basis.
Ram HD 6.4L has been using the ZF 8HP75-LCV since 2019
I guess I mean behind the Cummins....
I have a JL Unlimited Rubicon MY2020 with an 8 speed auto gearbox and a 2.2 diesel engine (European version) and 60k miles on the clock. When running cold engine and moving from 3rd to 4th gear I was getting a jolt, which obviously I shouldn't be as the jeep has a double clutch. Took it into service and the Jeep dealer they put it through the ODB computer and no error showed up. The dealer mentioned that although Jeep says that gearbox fluid is lifelong, obviously this isn't true as no oil or liquide is forever. Depending on the type of driving you do, you should have this changed every 60k miles at the most. If you do a lot of off roading, then the dealer suggested no later than 30k miles. It's not cheap though.... I paid 700 USD just for the liquid and the gasket. Huge improvement on the gear changes I have to say. New liquid and updated gearbox software did the trick.
I paid US$185.00 for seven quarts of Mopar 8&9 Speed Transmission Fluid (equivalent to the ZF-branded fluid) and the Mopar filter, 68417054AB.
Did you go with the deep version or the normal one?
Deep, I had to notch out the more skid (a stiffener than runs across the top) a little but other than that, it fit like a glove.
