Hi there,
I recently did an engine swap in this vehicle for a friend. The one that was in had spun a bearing. The engine is the same one that came out. Problem is, now the vehicle won't move anywhere. It tries to creep in 4Low, but nothing else. When I jack up the tires, they all spin, however they spin forward in both reverse and neutral as well. I have tried adjusting fluid level and bleeding multiple times, checked transmission filter and tried a flow test, which indicated no flow. No fluid is running through the cooler. Verified the lines are not blocked. I'm out of ideas.

Engine is an OM617 out of a W123 car, and the transmission is the stock 4 speed mechanical auto box that would come in a 1985 G wagon. I'm sorry I don't know many Mercedes terms, I work more on domestic diesels and took this job to help a friend.

Any help is greatly appreciated. I would rather be able to complete this job rather than having to send him elsewhere to fix this problem
