It feels good and it seems the gears are good. My question is: Is there really any way to "check" that tranny. I would just keep the tc as a spare or whatever. I have a 94 2.5 that 5 gear is gone and the syncros in third are shot. Do I get the collar, clip and syncros for my ax-5 or go with the ax-15. Im I just band-aiding the ax-5. As always thanks alot the help.
ps. I do know for sure that it is out of a wrangler not anything else
FYI your 4 banger is an AX-5. The swap can be made with a bell housing from a Dodge Dakota with the 2.5 in it.
The AX-5 is a weak tranny.
The AX-15 didn't appear in the Wrangler until very late '89 early '90. Before that it was the BA10/5. The spline count is different.
The BA10/5 and AX5 are both 21 spline, and the AX15 is 23, so if you replace the tranny with an AX15, you will need an NP231-J transfer case. Not the np207 or np231/amc. they are both 21 spline and will not work with the AX15.
Hope that helps.
