PPE on Mojave (Oil capacity)

[Rhino35]

Planning to change transmission pan from factory to PPE, for those who have done it, what's the oil capacity once you install PPE pan? Not sure if 8 quarts will be enough as I will order online. Thanks

I just did this. Because the total tranny capacity is 9 quarts, that’s what I bought. I figured the rest would be used on the next change, so no harm. I used around 6.5 quarts with a traditional drain and pan drop. It probably would have been slightly less if the tranny didn’t get too warm during the fill process, causing a bit to drain out. I then let it cool and checked it again. A bit had to be added as a result.

Edit: I should add that the tranny holds 9 quarts with the Oem pan. So maybe 9.5 with the PPE pan and the 3.6.

I´m looking at this option. I have a couple quick questions....1, did you use the Mopar fluid, ZF, fluid, or Valvoline Max Life ATF? I´m seeing a lot of folks running that Valvoline and haven´t seen anyone with an issue. I´m leaning toward the Mopar or ZF, but with extra capacity, the Valvoline would save quite a bit of money.

Second question is, did you wrap the exhaust pipe under the transmission pan to keep it from heating up? I´ve read of people doing that, but I am not sure it is really necessary.

I did all the research before doing this. Absolutely use mopar fluid. Because you’re only draining some of it, and lots stays in the tranny, you don’t want to mix fluids. Fluid is cheaper than a tranny.

I did not wrap the exhaust for two reasons. One, PPE doesn’t recommend it, so their own is built to expect the heat. They made the pan specifically with the crossover in mind. Two, wrapping the pipe will reduce heat around the pipe, but the pipe itself will be hotter due to its new winter coat, and can then crack. If you want to insulate the pan, the recommendation I received was to insulate only the top of the pipe to allow heat to escape below.

I forgot the other thing, I’d plan to replace the gasket. Mopar redesigned these with two sealing surfaces, very similar to the construction of the diff cover seals. Way better design. My original gasket was seeping. This one is doing great after some significant miles on it, and not easy miles.

Thanks for all the info!

Did you need more than 6 quarts to do the re-fill, and do you know the part number on the new Mopar gasket? If not, I can just go to the dealer and give them my VIN. I´ve not seen any seeping, but taking it off and re-using it might just be what starts it. So I´d prefer to have that new gasket, for sure.

Any time. I didn’t save the package, and did exactly that. Dealer with my vin. Mine took 6.5, but it would have been closer to 6 if it didn’t warm up during the fill and quickly overflow some. Watch that tranny temp during the fill and check. You really need two people. One in the cab shifting and watching temps, and one underneath.

Those look very nice.
