ba10 to ax15 troubles

[keeponjeepn]

i am new hear. just checkn to see if anyone knows if i need to change the inspection plate when goin from ba10 to ax15 transmission? also would a bellhousing from a 87 to 93 wrangler ax15 4.0 work with my 89 comanche 4.0.. the current bellhousing i have is from a 94+ ax15 external slave. but it doesnt line up 100% to the bolt holes on my motor. any help is apreciated

Did the swap last year.  The plate is the same for both BA and AX.

 

For the bell housing, there is no 87 or 88 AX15.  The AX15 first appeared in mid-89 in all jeep lines.  You'll have to examine your 89 to determine if you have the BA or AX.

 

The bell housing for the BA10 will not bolt to the AX15.

 

Later AX15s with external slave will have inter-changeable bell housings with earlier AX15s.

yea pulled the ba 10 out of the truck last week. tryd to line up the bellhousing that came with the ax15 i bought there is a bolt or 2 that just won't line up

[87MJTIM]

You'll need to get a bell housing for an AX15 (not AX5 or AX4).  Preferably an external slave bell housing - 94+.

as far as i no that is the bellhousing i have. 94+ external slave. . there is just one bolt that doesnt line up. and also do i need to change the crankshaft sensor

[87MJTIM]

Do you have a picture of it lining up to the trans?  I swapped a BH for an internal slave and external and everything lined up.  (90 AX and 98 AX)

[keeponjeepn]

[87MJTIM]

this is the bellhousing that is from the ax15 that doesnt line up correctley

[keeponjeepn]

i will try to post a pic up early tomorrow of it sitting on the motor

[87MJTIM]

i am not near mine, but I don't remember the flat edge in the lower right of the picture.  I thought it was rounded most of the way around.

[keeponjeepn]

did they make the ax15 for the 258 motor

[87MJTIM]

The 258 and 4.0 are the same engine block.  I put the 90 AX15 on an 84 CJ7.

You can compare your bell housing to the one in this thread...

[87MJTIM]

If the bolt pattern does not match up, you may have an AX5 bell housing.

Here is a shield for an AX15.  Compare the lower right portion to your bell housing.  Yours has a flat/straight side.  The shield has a more rounded edge to it.

I did this swap in September and it lined up fine

[keeponjeepn]

Ok so its because my truck had the ba10. Theres one hole top center on my ba10 sheild. No hole in ax15 bellhousing but i got it on the truck now. Srry guys this is my first project jeep

[keeponjeepn]

I got a brand new luk pro gold clutch from my buddy pretty cheap. Do i need to change out the flywheel for this tranny swap. And will my crankshaft sensor in my truck work

[87MJTIM]

I kept the flywheel that was with the BA10

 

The CPS goes with the flywheel and the engine electronics.  It doesn't care about which trans you have.

 

Good to hear you got it lined up.

Also i have the ax15 bellhousing internal. I no i should convert to the external but at this time i am very limited to cash for this. My truck originaly had an internal slave with the ba10. Can i use the ax15 internal bellhousing on this ax15

[keeponjeepn]

If i use the cj pilot bushing do i only use the bushing and not the actual bearing?

I used just the bushing.
