Question on manual transmission additive- newbie owner here

So this is my second TJ, and I got a 2005 rubicon this time and in finding it a little difficult to shift compared to my 05 X.

I have this tube of JB gear oil treatment that I have used in a couple of motorcycle transmissions, and wondering if anyone here has used it before and if it would harm my trans in any way? This stuff has worked well in my other vehicles, but I thought if ask the pros on here before I stuff it in my jeep.

Thanks!

have you tried changing the tranny's fluid with approved fluid, synchromesh compatable ?

Yes. I just changed the fluid about 1000 miles ago.

Exactly/specifically what lube did you replace the old lube with?

When you have a choice, buy American.

There's other threads about the 6 spds being difficult, the fix is often Royal Purple Synchromax or equivalent.

I used Kendal versatrans full synthetic ATF ( equivalent to dextron 6 I guess) based on what was recommended to get by my local off road store.

Wrong stuff.

Your tranny requires synchromax/synchromesh compatable fluid.

I would put the correct fluid in before trying any additives

You have several choices to choose from, some synthetic, some non synthetic.

Ok. After reading a bit that's the thought I had. Yikes. Hopefully the stuff in there hasn't caused any harm. Is the fluid capacity correct at 1.58 quarts?

Maybe you should visit the "sticky" section.

Redline MTL is one of the very best synthetic transmission lubes made for your particular transmission. You can get it from www.summitracing.com. Our Jeep transmissions are fussy about their lubes, don't use just any "transmission lubricant".

Mine's the NV3550, not sure what the OP has. When I notice mine shifting difficult I've found instant satisfaction after draining/filling it with the proper fluid. Happened 1st at about 50k miles, put the Royal Purple Synchromax in and it was smooth for 30k miles and then was acting fussy so I changed it again and was happy again. Been about 15k since. Always kind of wondered if the factory stuff being that it lasted 50k might be better than the Royal Purple, or my jeep just got to an age when it might be needing a fluid change every 30k? Guess I'll know in another 15k or so. I wonder if there is much of a difference in longevity/function between OEM, Synchromax, or the Redline MTL?

Thanks guys. I just picked up a couple quarts of the RP synchro max and am going to change the fluid tonight, providing that the trick-or-treaters let me get it done lol. Thanks for the help!
