Just ask @cosine he knows!
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 ??

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.
