Amsoil Transmission Fluid in ZF 8 speeds

[RodRamCar]

Has anyone done a full trans fluid replacement using the amsoil recommended fluid for the ZF 8HP70? Whats your experience snd did you do a full drain and fill x3 to get 90%+ OE fluid out? Always makes me wonder how one fluid can react with another. There must be enough similarities that they are equivalent although ZF will never admit anyone else makes a safe fluid for obvious reasons.

When i have enough mileage, ill be changing over to amsoil trans fluid, everything else has already been changed over.

Yes at 10 k with a OEM pan. 20 k now checked it once at the specified temp and was a little over but it handles boost and abuse just fine

While I used Redline in my tranny, I did a drain and fill 3 times to get most of the old fluid out and switched to a PPE pan, it is much easier to access the drain plug.

Nice stash you got there. Right now I have Valvoline Full Synthetic front and rear diff with LS additive and Mopar BW 44-44 xfer case fluids with Redline 5w30 and RP 20-820 filter. Probably will go to the -500 part number next. But I'm wondering if 5w20 will be good oil if using Amsoil as it's impression the Redline having the high ZDDP will provide better upper cylinder protection

Mopar trans fluid is over 2x more expensive and amsoil is the one company besides redline and Ravenol I would trust to put in my vehicle

All I can say is amsoil works for me in everything except the Procharger And archoil that I add to everything at 1.2 oz per qt.

Redline in the 8 speeds doesn't have a great rep,it's to "slippery" .It's one of the fluids alot of the better 8 speed tuners reconmend staying away from,as it contributes to more clutch slip.Not sure about AMSOIL's fluid though. If Redline is working for you,you're one of the few it is,but don't say you haven't been warned.I'd use Valvoline Max Life before i'd use Redline in the 8 speed

I haven't noticed any slippage of any kind so far but when doing another change am thinking of using Maxlife as many have said they have good results with it and the price is much more attractive.
I also used the same Redline in my 2011 Ford Fusion as it specs the same fluid and am happy with the results.

For those that can get it to work it actually would be a great thing to run with those operating temps, but yeah a significant number of ram guys have not had good luck with it.
