I'm going to hit 30K on my 2006 Commander that I bought new, and want to change the fluids. I cannot find the torque values for the bolts on the rear differential, transmission pan, and axel fill plugs.

Also, I have the 4.7 with Quadra Track-II. Is it using the NV 245 transfer case? The manual says ATF+4 but that does not seem correct for the engine and Quadra Trac-II system that I have. I need clarification on what fluid is intended for this system.

I have the MoPar transmission filter already purchased. I need to get the fluids next.

Lastly, if there are any 'tricks' to be aware of, please let me know. It looks like it will be a bit tricky getting the fluid in the transfer case.

Thanks!
Frank.

There might be a TSB out for the NV245 Fluid, or maybe it was just changed in the later owners manuals to use a different fluid, that is available from the dealer. Hopefully someone will chime in with a better answer for you.

I have the NV140 and I just used the AMSOIL Synthetic ATF, calls for ATF+4, read below.

If your still in warranty, I'd only use the recommended fluids in the O.M., experiment with something different and they could hassle you about a warranty claim and even deny it if its related in anyway.

AMSOIL 75W-140 Synthetic Gear Lube should meet all the specs in the O.M. for the axles, thats what I used, Mobil1 makes it also. Remember the O.M. says "Synthetic".

Only ATF+4, that says ATF+4 on the front of the bottle, meets Chrsyler ATF+4 spec. Sure, AMSOIL, REDLINE and MOBIL1 will claim their Synthetic ATF, meets all the specs for ATF+4, but its NOT certified by Chrysler (thats why it doesn't say ATF+4 on the front of the bottle) and technically it doesn't meet all the specs. Sure its great fluid, and judging from I've seen you can safely use those fluids in ATF+4 applications, but when it comes to dealers and warranty, expect them to stick to the line, its doesn't technically meet the spec, its your fault the part failed.

Torques from the 2007 FSM:
NV245 Drain/Fill Plugs 15-25 Ft-Lbs
Front Axle Drain/Fill Plug 44 Ft-Lbs (Non ELSD)
Rear Axle Cover Bolts 30 Ft-Lbs (Non ELSD)
545RFE Pan Bolts 105 In-Lbs (NOTE, THAT IS INCH POUNDS NOT FT POUNDS)
