Anything besides Redline MT90 to help smooth shifting in my AX15?

Just received my second jug of MT90. First time I used it, tranny got flooded with water somehow. So I drained it and put some 10w30 in it to help flush it out. Is there anything else I should add to the MT90 to help smooth shifting? My 1st to 2nd grinds and my 2nd to 3rd catches most of the time... 160k on motor and tranny, and the clutch is fine. Just hoping this MT90 helps the synchros chill out.

MT-90 is excellent stuff & my #1 choice for the AX5 and AX15, but it's no miracle treatment for a transmission. Try it, it might help, but whatever you do don't add any additives. There are no additives that would help and most would only reduce its effectiveness.

I use MT-90 and have 107k on the jeep. I have a lead foot and shift like a gorilla and its smooth as butter but when its cold outside reverse is hard to find sometimes.

By "hard to find sometimes", do you mean Reverse sometimes grinds when you try to shift into it?

Jerry, I just drained my fluid and found water in it AGAIN. The only two places it can get in is at the breather tube and the shifter boot that is directly mounted to trans, not the interior one, correct? I think my shifter boot is ripped. How do I install a new boot? It looks like this boot is in here permanently...

Hahaha no. I'm thinking when I was pressure washing after my last wheeling trip water got in through the ripped boot ontop of the tranny. Any idea where to get a new boot? This 10w30 I drained out of it was basically white lol

I'm sure you already checked e-bay and even googled it, right?

Well never mind, I guess that gasket above just keeps heat out of cab. I looked down in there and it looks like the gasket that is in there is fine... Not sure how water keeps getting in my tranny...
