Time for the Ax-5 to go

My clutch went out in my 95, 2.5L, AX-5. I may as well swap trannys if I'm going through all this.

Is this SM420 that's been modified to fit in a jeep just like mine a good swap?

The seller swapped it out for an AX15, so it must not have been great...

But Muncie transmissions are great especially for people who drag, they are strong, hell offer the guy 75 bucks see if he will take it if not go to 100

I built a muncie 465 for another member on here, It went pretty smooth all things considered. If you can find the post by "ldso" titled "jk dana 44 swap thread for my yj-slowly" At the end is some info on the swap and review. He loves the lower first gear. I did the rebuild, bell housing mods, and what fab work there was. The 420 is a good trany, but I personnally perfer the 465. I'll help if I can. Ron

If it not your daily driver, I would go for it. Worst case is you do not like it and then have to swap in an AX-15 anyway. Just sayin.

Do you have to modify the drive shaft for the Muncie swap? If you do then have to again if you go the AX-15 route I might not.

The 420 is not a good choice for a 2.5l. Even can be not ideal for a 4.0.

The splits in the gears are very very wide. If you do not have the power you are going to be way reving in one gear, and bogging in the next. Also you would be losing overdrive if that matters to you. Also these transmissions shift very chunky and slow, and they make a lot of noise. They do work great behind a v8 though

The swap I helped with has a 2.5, 4.88's, and 33" he does complain about the gear spilt. He is mighty slow on 4 lo and first gear. Ron

the worst split is from 2-3. I even think the ax5 split from 2-3 bog sometimes on big grades and it is a TON less.

Ax5 is
1- 3.93
2- 2.33
3- 1.45
4- 1.00
5- .85

Sm420 is
1- 7.05
2- 3.58
3- 1.70
4- 1.00
