AX-15 transmission overhaul

1584 Views 2 Replies 3 Participants Last post by  Beat95YJ
I have 92 Cherokee 4.0 with an ax-15. I have put on 70k of the 100k currently on the odometer. I just dropped the transmission to replace the throwout bearing.
I am wondering if there is any benefit to me doing any sort of major overhaul on this thing while its out (not myself, but taking it to a trans shop). I can’t say the transmission has given me any problems. Clutch has gone out a couple times. But nothing with the actual trans. But just wondering if it would benefit from some extra routine maintenance before input it back in.

Just put new fluid in it and go. I like redline brand or penzoil synchromesh. I’ve had my AX15 for years with zero trouble. Better than the nv3550 imo.

I rebuilt mine at 110,000 miles. There was no reason to do it but I broke the bell housing and the input shaft was f’d.

If it shifts well and doesn’t grind, I would change the fluid and put it back in. Hell I’m cheap, I’d probably run the same fluid.
