6 Spd Transmission lube change...

Yesterday I changed the transmission lube from the factory fill (Pennzoil) to Redline MTL. I cannot emphasize what an amazing difference there is shifting. Not nearly as rough or notchy. Quiet, smooth and easy to shift, HUGE difference. I have 3K miles on the JKU. I admit to being a fan of synthetics for a long time, I used Royal purple in my last manual trans, the Redline in my opinion is far superior.
Try the Redline in your manual trans, you will be surprised at the difference.
I am not a dealer or employee of Redline, just pleased with it.
Bob

I definitely want to do this in the next few weeks. How many quarts does it hold?

Takes 2 quarts, so far as I know there are only 2 synthetics that meet the transmission spec (MS 9224), Redline and Royal Purple. You do not want others that contain an additive that will corrode the syncros.
I'm going to change the front diff to Redline tomorrow. Rear one is anti spin so I'm waiting for a reply from them on how much if any friction modifier to add. They do make a 75W90 wt. diff lube specifically for the anti spin, i'm just cautious.

I may have to do that as well. I'm okay with longer throws and somewhat rough shifting, but my tranny has been SO clunky that I've already taken it in to the dealer to have them drive it. Of course it was driving perfect that morning, but even since - it grind into gear and just does not feel right.

I know Amsoil also makes a synthetic fluid that meets the Chrysler spec. I know some guys than run it, it is what the local Jeep shop recommends. I don't use it as I have an auto.

You also mention having only 3k miles. One thing I've noticed is when brand new these things are crazy tight. After some miles, the feel of both engine and 6 speed really improve. Shifting gets easier, power delivery is smoother, and it feels happier at high RPMs.

How did you change the trans fluid? Im just curious because I have the same 6 speed NSG370 trans in my 06 TJ and I went to all kinds of places to look for an Allen wrench big enough to change my fluid and couldn't find one anywhere! I guess my question shoud be where on earth did you find an Allen wrench that big?

Wrenches..

I got both the allens required from Sears, order online with store pickup. It takes a 17mm and a 14 mm.
I know the trans would "loosen up" but I want better shifting with as little wear as possible. I want this thing to last, so synthetic works right away. If the Redline does as much for the diffs as it did for the trans, I'm gonna be a happy guy!
The LSD does take the 75W90 without modifiers....

mang318, changing it is pretty easy. I suggest picking up some kind of small hose while you are getting the fluid that is a couple feet long. I am running an 05 unlimited right now (only cruising these pages because I am gonna get a four door when I get back to the states for the new little man in the family) and changed the fluid in mine a few months ago. The reason for the hose is to put it through the cap or on the bottom of a funnel to get it in. Where the fill is for the tranny is pretty tight and can be a pain getting it back in. I ran the hose down through my shifter boot and to the fill hole. Super easy.

Royal purple is garbage transmission fluid. Redline is pretty good, but for your next change, try amsoil. Redline is great, but doesn't last and the shifting degrades after 5000 miles or so. Amsoil is like having your tranny lubed with double cream.

IF anyone wants to know, the best diff fluid money can buy is LE607 (has been renamed to LE1605). Nothing else comes close, including Amsoil (and Im the biggest Amsoil fan.)

Water Separation of LE 1605 Duolec Gear Lubricant - YouTube
So, it just means LE1605 is much less polar causing it to separate faster. This test is no indication of deterioration in lubricative properties of the other oil. If anything, it says that in the presence of water LE1605 will tend to blob together and your gears will be lubricated with water. Also, what about the fact that metal surface is phobic for polar molecules? That would again indicate that the other oil is a better lubricant!

Yeah, Amsoil is also compatible with Chrysler's MS-9224 standard for manual transmission: AMSOIL Manual Synchromesh Transmission Fluid 5W-30

As for Royal Purple, if you look at their transmission lubricant cross-reference sheet the Synchromax is equivalent to an ATF. ATF is less viscous. If you want to run ATF in your manual gearbox go ahead and use Synchromax, but I am not doing it for sure.

Royal Purple's Max Gear 75W/90 is rated to meet GL-4 and GL-5. Keep in mind, that GL-5 are lubricants intended for differentials where there is no copper or brass. GL-5 is bad for manual transmissions because it corrodes synchronizers.

Redline is great stuff in the manual .Thought my sons TJ had a bad tranny shifter felt like a broomstick in a bucket and as a last ditch effort put in the redline and it shifts like new going on 10k miles now and still shifts great.

I did not notice any degradation in the shifting in my last jeep at 20K miles, difficult to believe Redline will degrade in less than 20K. That said, I do change the trans lube at 20K unless I go through deep water, then all lubes get changed.
