where are you guys coming up with 2 quarts of transfer case fluid?

I just changed mine today and I only pulled out 1 quart, and put back in 1 quart of fluid from the dealer. The dealer also told me it shouldn't take more than a quart anyways.

I'm confused.

Dealer is clueless. Factory spec is 3.8 pts. (60.8 oz./1.9 qts.). Average used seems to be around 40-55 oz.

Idk why the dealer would tell me that 1 quart is more than enough.
Do you guys fill those cases up til it starts overflowing and then levels itself off?

I just wanna make sure I don't **** up that transfer case.

Not surprised. They often confuse the capacities between different t-cases (example - the NV140 takes about 23 oz.).

Fill level is 25-35mm (0.98-1.38 In.) below the bottom of the fill plug. You have to fashion a dipstick from a piece of rod, putting a 1.5" or so right-angle bend at the end. I made one and painted the end flat white, as on the rod piece I originally used (from coathanger) the oil would run right off it making it hard to measure the level.

I assume you drained the fluid while it was warm/hot, and let it drain 15-20 min.?

Looks like the dealer put limited slip additive in with the axle fluid.... Besides being inappropriate for our model, is it going to hurt anything staying in there or do I need to get them to replace it all?

Kicking the dead horse to revive it...so it can then be killed again, and kicked more....

I think I know why the dealer is clueless. Besides actually being clueless and inept, the confusion is also in writing...

Dealer gave me printout of something that is labeled:

2010 - WK - Jeep Grand Cherokee - 6.1L SRT HEMI V8

04 - Vehicle Quick Reference/Capacities and Recommended Fluids/Specifications


It proceeds to list out a table including sections for Cooling System, Engine Oil & Filter, Fuel, A/C, Plugs, Trans, T-Case, Chassis, Axles, etc. The table includes descriptions, part numbers, and capacities for a number of items.

In the T-Case section, all three t-case models are listed, however for the NV146 (6.1L engine only) row, it indeed lists 1.4 Pints as the fill capacity. This is roughly 1/3 of what everybody is filling to... I called Chrysler this AM and I'm awaiting an official response on the written discrepancy from their technical group. This must be what the dealer service technicians are following during service and when asked. The lady from Chrysler couldn't track down the answer herself based on the documentation in hand - no wonder there's confusion!

Does anybody out there have an up to date FSM, that calls out the NV146 fill capacity? If so, what's the page/section number, have a screen shot to post here, a pdf, or anything official on what the right answer is? Also, if this Quick Reference section is in there, confirm what it says, and if there's a more detailed description elsewhere in the FSM on the capacities, please post what you find.

I've been referencing the nice write up on wkjeeps and all the posting on this forum for technical information. In this case, it appears the Chrysler Quick Ref docs are wrong??!!

If you have an FSM that covers up through 2010, PLEASE post what you have on this. Thank you.

My Saturday NV146 and axle fluid changes appear to both be botched and I'd like references to walk into the service department with. Unfortunately, wkjeeps printout won't be treated as official...
