Engine/Transmission (1998.5 - 2002) Lube Spec for NV241HD Transfer Case

[BT]

The shop manual for the 2001 lists Mopar ATF +4 type 9602, Automatic Transmission Fluid for the NV241HD. I want to drain and change with a Redline snythetic, but looked at the Redline page and they list:



Synthetic ATF

Synthetic D4 ATF

Racing ATF

C+ATF

High-Temp ATF



The only one that even mentions a Chrysler spec is C+ATF, which meets Chrysler MS7176??



Anybody know which Redline to use? I'm wondering if I use the wrong one, if the transfer case won't shift properly on the fly, etc.



Anyone know or has used a Redline oil in the transfer case with good luck??

I use the High-Temp in mine, works great! You could probably use any of the "Mercon" rated fluids with no problem.

Back in 1997 there was no +4. Mopar recommended +3 or Dexron 3.

I used the Amsoil ATF. 100k miles no issues.

The correct Redline for the T-case is D4 ATF. You can use the high-temp if you want something a little thicker, but it might not shift as well.
