Fluid for nv5600

[RV2]

What type of fluid should I put in my 6 speed and how much?

 

[RV2]

nobody can recommend trans fluid for me?

Chrysler Part No. 4874464 (Specification MS-9224), Pennzoil Synchromesh fluid.
Even better get Amsoil.

Redline MTL is a great choice, worked very well in my 2001. Avoid Royal Purple.

Over fill with amsoil. As expensive as they are to rebuild or replace don't cheap out on fluid. IIRC you can over fill by 2-3 quarts if you remove the shifter.

why avoid RP

Thanks for all the answers!!!!!

why avoid RP

I tried it and from experience dont do it. It ruined my 3 gear syncro. Never had a problem till I put that junk.

Ordered 6 quarts of amsoil today!

I put amsoil in my NV4500 and even a sub-zero temps still no problems with shifting.

Why would you suggest that you over fill it?

Why would you suggest that you over fill it?

it's been said that if you tow or pull alot of hills the oil will not lube the front bearing very well and it is prone to fail then.

I drained the fluid in my 5600 and added 6 quarts through the shifter opening, but looking into the trans I could still see the top of the pto cover and the top bolt, should I add more fluid or is this sufficient?

pull the fill plug from the side and if it runs out it is good.

 

[RV2]

It is above the fill plug on the side

Is the truck siting level? How far below the top PTO bolt is it?

I am just wondering for a sight glass I may add.

You are 1.25 quarts over the factory spec, unless you are pulling tons of wieght, you ought to be fine.

I would put like 8-9 quarts in it they shift much better. Had a 5600 that would grind in 5th and 6th if shifted fast with 6quarts. Was told to fill it up all the way and it shifts fine now.

 

[RV2]

The truck was sitting level and it was about 1/2 to 3/4 of an inch below the bolt hole.

I've never had issues with my tranny. Fluid is Factory from 2004 with 121k miles. But when I do change it, I'll go with amsoil and over fill it above factory spec. I've read great things about amsoil and only plan on changing it once and let it go...
