99 5speed tranny oil?
 
Ok so i have looked around here and found 97,98 but nothing on a 99 tranny.

I'm having my tranny fixed tomorrow and dont want them throwing in some crap that came from a 50gal drum in there.
So i told them i would bring in the stuff to put in there...
Now i just need to find out what i need to buy...lol

Thanks

redline =MT 90

Exactly, you can't do any better than Redline MT-90 for your AX-15 transmission. You can get it from Summit Racing - High Performance Car and Truck Parts | 800-230-3030 and read about it at Red Line Oil

just plain gear oil is fine

X3 on the MT-90. I noticed a world of difference when I switched over.

Just plain gear oil like we use in our axles is a GL-5 and the sulphur-based additives in most GL-5 gear lubes are harmful to the soft yellow-metal synchronizers in our manual transmissions. That's why the factory stopped specifying GL-5 for the AX-5 and AX-15 transmissions. :)

is that fluid also the best for an 04 rubicon manual... not for my jeep but for my buddies we doin his fluids this weekend

No, I don't believe MT-90 is the best match for the newer transmissions. They do better with something like Royal Purple Synchromax (a synthetic) or Synchromesh (a non-synthetic) from either Pennzoil or GM.

thanks jerry once again..

Have the dealer do it. That way when it goes out, dealer can put in a new one.

KellyK 10-24-2008 07:00 PM

Well since i couldnt get it in time for them to put it in i will just order it and do it myself...

Obama? and you own guns?.... guess you dont want to keep them that long.
He wants to put a yearly tax on guns. Tabs for the jeep and tabs for the Hk

With the 2000 you should have a NV3550 (assuming you have a manual you didn't state.) You'll need the Synchromesh.

AX-5 and AX-15 = redline MT-90

Correct. Another good alternative for the NV3550 is Royal Purple Synchromax which is a synthetic. Synchromesh from GM or Pennzoil is fine too but is a dino gear lube. :)
