Transmission Question

Howdy,

I have a 2004 Wrangler TJ X, L6 with a manual trans that I bought at the end of December '17. She has 101000 miles. Yesterday I changed the transmission oil. There was only about one quart of fluid in there which was probably the reason there was a fair amount of noise when the trans was in neutral with the engine running. There were some minor metal chips on the drain plug magnet which I would imagine is pretty typical. There were also some small brass flakes in the drain pan. Also imagine that this is typical for the age of the transmission. Please feel free to comment if my assumptions are incorrect. Big question is the transmission only took three quarts of oil but everything I have read the NV3550 should take 3.5 quarts on a refill. Any ideas of why the trans only took 3 quarts? I let it drain for about 45 minutes and there was nothing dripping after that time.

Thanks - Fonz54

You'll likely still hear that "marbles in a can" noise in neutral after you put in new fluid. It's normal. What fluid did you use? Be sure it's safe for the brass synchros.

Stop over thinking.... fill it up to the bottom of the fill plug and then put your remaining energy into waxing the paint

The marbles in the can analogy is a perfect description of the sound. It has definitely quieted down. I think part of the reason the marbles were excessively noisy was because the fluid was low. I used Redline MT GL4 oil.

Going to change the Transfer case fluid and the gear lube in the differentials this weekend.

MT 85/90 or MTL? MTL is the correct spec for the NV3550. I believe MT is correct for the AX-15 but the NV3550 should only have MTL.
