Recently I was researching swap options for my 2008 Jeep Commander 3.7L QTI awd. I have yet to see a 4bt WK, let alone an XK. I think it would be interesting and unique to say the least. I’ve recently acquired a 02’ TJ from my grandfather and now that I have a second rig I’m feeling more and more motivated to swap it. The 3.7L is anemic and I love turbo diesels, especially the interesting ones like the 4b’s. I have zero plans of ever selling this unit as it was the first car I purchased myself and it has sentimental value. Do any of you have experience with a swap like this? Or know someone who does?

I wonder if it would be easier to find a wrecked crd WK and swap over the engine harness along with the crd ecu, because I believe it uses the same trans. They made them overseas but we never got a 3.0 Turbo Diesel XK in the states.

Hi
Fwiw. The CRD uses a transmission made in germany by mercedes. Jeep called it W5J400. The 3.7 used a W5A580 made in Indiana. There may be subtle differences that may cause issues, so do your homework. The unit fitted to a Diesel has a different torque converter. If you plan on performing a transplant i would get a crd transmission too.
