Ax-15 OR NV3550 manual trans
I have a 97 Tj Sport 4.0 5 speed with the Ax-15 tranny in it, with 80K miles, only shifting problems ive had with it is Reverse is a pain sometimes (which from my understanding is common).
Buddy of mine has an 03 Tj Sport 4.0, 5 speed, with 60K on it but has the NV3550 trans.
anyway i drove his the other day, and his trans seemed A LOT quieter, and quite a bit easier to shift than mine (his shifts like butter, where as mine takes a little push into gear..doesnt take an excessive effort tho), and others have said the same exact thing
so just to start with the basics before i go on a wild goose chase... i changed the fluid in my trans to the recommended grade and weight. no change..
So My question for you guys is
Is his NV3550 a quieter, smoother shifting trans.
or is my AX-15 just a little old and tired causing the harder shift, and the bit of extra noise.
What do you guys think? interested to see because if the NV is better than the AX im considering a swap. if not im just gonna rip the AX apart, see if it needs anything (possible rebuild) then put it back in.
