87 comanche Posted January 17, 2009 Share Posted January 17, 2009 I just bought an 87 comanche 4.0 5spd. It grinds when I down shift to 2nd every thing else is fine. Should I rebuild the ba 10 or swap to the ax 15? It came with a 3inch lift and I plan on putting on rubicon wheels with 31s. I am not going to really be offroading it light fourwheeling. Would it be worth the time and money? Thanks Link to comment Share on other sites More sharing options...
BLHTAZ Posted January 17, 2009 Share Posted January 17, 2009 Swap it...rebuilding that tranny is like rebuilding a broken D35 :shake: . The BA10/5 is hard to find parts for and they are expensive to rebuild. You could probably do the AX-15 swap for less money. :cheers: Link to comment Share on other sites More sharing options...
87 comanche Posted January 17, 2009 Author Share Posted January 17, 2009 Thanks. The ax 15 mounts up preaty easy? Are you going to end up changing yours over? Link to comment Share on other sites More sharing options...
BLHTAZ Posted January 17, 2009 Share Posted January 17, 2009 Yes, the AX-15 is a pretty easy swap. There are a lot of write ups on doing it...some on here and many you can find with Google. I will change mine when it goes bad, but for now it works like a new one and my truck is strickly show / street so it never gets any extra stress on it ;) . I have a 32RH tranny laying in my shed out back that I was thinking of putting in our YJ, but it may go in the MJ if needed. Link to comment Share on other sites More sharing options...
