How far are you from getting the 4.0L back into the maroon XJ? You wouldn’t feel so overwhelmed if you finished one project at a time. When you are looking at multiple vehicles in need of multiple repairs (and your DD is held together by duct tape and wire), it can drive you nuts.

You need a process. Instead of buying more projects, focus on completing the tasks at hand. One project at a time.

It’s an AISIN transmission, not an Allison.
