Been thinking about what to do with my transmission on my 97 TJ project,it currently has an AX15 with 190k on it. Stock4.0L for now but I plan on swapping in a 5.3L vortec truck motor from an older Silverado or Chevy van. Would a rebuilt AX-15 hold up? If not what transmission should I be looking into, would like to keep it a 5spd if possible.
