2nd Gen Non-Engine/Transmission Amsoil ATF in NV5600?

[LStanphill]

Just turned 100k. Put amsoil in everything front to back. The amsoil did not have a cross reference for that chrysler syncromesh, so we put amsoil atf in the 6 speed & transfer case. I've put 1000 miles since and no gear clash or any other problems. Can the atf damage my 5600 or am I good to go? Lee

Yes!!! Get that out of there!!!!



The NV5600 takes a specific lube. More like a 10W-30 then an atf.



There is a Penziol lube that is Factory approved. Many have used Amsoil 10W-30. I have Redline MTL in there.



But do not Run ATF in there very long!!!!



I have Amsoil ATF in the Transfer Case. Works great!

ATF is way too light of an oil for the 5600.





Run Red Line MTL!

Amsoil Series 3000 5w30 HDD in the engine, NV5600 and the T-case. Has worked great for many miles. Drain the ATF out of the 6 speed right away.

I agree with Cumminspower. I am running the series 3000 5w-30 in my 6 spd and it shifts easier. The ATF is to thin and does not have the same lubricating qualities of good oil.

I'll change it out to the 5w30 amsoil... Thanks for the replies!
