I have a 1992 YJ that we bought for our oldest son a year and a half ago. It has the AX15 in it, but as much as I want him to learn to drive a manual it is posing much more difficult than I imagined. He has Aspergers (High functioning Autism) and the added pieces of driving a manual in traffic is posing too much for him. I am now looking into swapping the AX15 for possibly a 30RH. I am not sure what all this would take to do or if it is possible without spending an insane amount of money. Any help or advice would be greatly appreciated.
