ever think of using a dodge sprinter engine with a zj tranny like in Europe

Aren't you using a TPS adapted to it, so you retain the TCU as it is?

Hi Jeep-dsl, thanks for doing the aw4. I had mailed you about it I guess a year ago. Are you doing anything for a pilot bushing for the nose of the torque converter to the MB crankshaft? Or am i missing something? I assume you are using the AW4 torque converter?. I hope to convert my '96 xj 2wd. If I buy your oil pan how much if any lift will I need

thanks

Bump
 
Did this build ever get finished?

I bought Jeep-dsl's adapter he started making and I did complete the swap. I made a bracket to hold the TPS sensor and the AW4 worked just fine. My engine, on the other hand, spun two rod bearings shortly after the install and I have not found a crankshaft for a reaonable price. When it first failed i was so disgusted with the whole thing I ripped it out and bolted an AMC 304 out of my CJ-5 to the AW4 and our little cherokee has never been more fun! (The CJ-5 got a 401!) I still have the OM617 and adapter if I can ever find a good crankshaft I'll put it together for something else, maybe. It could also be for sale. I'm still a fan of this idea and I would have kept the OM617 in there if the one I bought wasn't junk, it came from a wrecked car and I'm betting they ran it without oil after the front end collision killed the oil cooler.

Oh wow that sucks about the 617, I was hoping to find out how it did cruising on the highway, there's a slim chance I may know where a crank is I'll have to talk to a guy first though

Mine has 4:10's in the axles and 32" BFG's, It cruised at freeway speeds fine until it started tying up like a 2 stroke. I never got any mileage numbers out of it, didn't run long enough. It did move along ok though. Not fast, but adaquate, I wouldn't plan on towing much with it or anything like that. I'm interested in the crank if it's cost effective... mine would have to be machined .030 or .040 under and bearings aren't available. Machinists locally here are affraid to weld, regrind, and re-nitride it.

Towing is definitely not something I do with my Jeep ever since I had a bad experience towing with it, and I use to drive a 83 300D, those engines definitely ain't for speed, I just don't want to have to be revving it high to maintain a highway speed

Hey guys, a little personal experience here. I had an XJ with the OM617, was talked out of using the AW4 and going with the 700R4 because of the TCU. Big mistake, I had a love/hate with the Jeep mainly due to the 700R4. I always regretted not trying to keep the AW4. Sold said Jeep and later did another XJ but this time using a Kubota 2.2 along with the AW4, way better trans. Wish I could have gone with the AW4 with the first jeep, probably would have kept it. Once you get the TPS dialed in it's a SWEET trans. behind a diesel.

So you didn't use a stand alone trans controller?
