Transmission fluid type?

[blnewt]

Thanks. So the ZF 8HP50 is the same thing as the Torqueflite 850RE?

Not sure, it may have been renamed going over to Chrysler but ??

It's in all the JLs AFAIK. There may be different model numbers but they're all ZF 8 speeds that require the same ATF.

^^^^ this ^^^^

ATF+4 is NOT the correct fluid. Either Mopar 8+9 speed fluid or ZF Lifeguard 8 fluid.

The ZF8 also has a special process for refilling after a fluid dump.

Hello Brother, may i know if i can use ZF Lifeguard 9 fluid instead ?

I want to dig into that, because I have heard "rumors" that Lifeguard 8 is being phased out. Hard to believe that it is given that Lifeguard 6 is still around.


@PeterKH - I have opened a ticket (ZF Services Request #961736) with ZF asking if LG9 is compatible with a 850RE transmission. I will post the answer here when received.
