Input and output shafts of what? I swapped a 999 into a 2.5L comanche a few years ago, all you had to do was remove the pilot bearing from the crank, swap the flywheel for a flexplate and adjust the driveshaft lengths.
-
Are you switching from the 5spd to the 999? If the 999 is compatible with the 2.5L, you have to change the transfer case input from short 21spl to long 23spline.
-
what about the input to the tranny from the engine ? same as the ax5 ?

i am removing the ax5 and putting in the 999

Input from tranny to engine?
-
tranny to engine shaft.
-
I'm not familiar with the 999 tranny, but if it was commonly available behind the 2.5L you'll likely just have to put in the appropriate pilot bushing.
-
The TF999 was the auto found behind the 4.0L
-
Good luck with that.

I thought it was the TF904 (3Speed)?
-
This came out of a 87 with the 4.2l
-
TF999 was also used behind the 2.5L in some cherokees and comanches

YJ from 1987-1991 with the 2.5L and 4.2L engine, and in the XJ in 1991 with the 2.5L engine.
If was originally behind a 4.2L then it isn't going to fit on a 2.5L. You need one that was behind a 2.5L

It should bolt up, just need to change the input shaft. Did they not all use the same bolt pattern ?

Are you talking about the transmission or the transfercase now?
What did the TF999 come out of? If it came out of a 4.2L YJ then it has the wrong bellhousing to bolt to a 2.%L

Tranny. Did the 6 and the 4 not share the same bellhousing ?

Nope, never have.

So did you use a dakota housing or what ?

I'm getting pretty confused, but here's a shot.
I had a 2.5L Comanche.
I used a TF999 from a 2.5L Cherokee
A TF999 does not have a removable bellhousing, the trans has to match the engine.
On my YJ I have a 2.5L
I used an AW4 from a 2.5L Cherokee
-
I see. I was under the impression you used an aw4 from a 4.0L . Hmmm. I might have to make an adapter plate for it if i want to use this transmission.

Sorry, I was confused for a sec. The 909 and the 904 were the same minus the converter.

AW4 has a removable bellhousing, so you can use any AW4 as long as you have the correct bellhousing for your application.
999's are a dime a dozen, not worth the effort to try to adapt a 4.2/4.0 999 to work with a 2.5

The AMC I6's use a different pattern then the 2.5L's for the bellhousing.

Fine.. I see i have been beat. If i cant mate the tranny to the motor, i might as well just swap out the motor. I have sold my blower, so i think its time for a 360. THEN, i can use the 999......
