There are two places in Northern VA that say they will actually try to repair a transmission: Don Pool, and MB Motors on Pickett in Fairfax (703.534.4222). When I talked to them about my 380SL trans, they recommended a partial rebuild, and they were quite knowledgeable.

The governor repair is tough. You have to remove the driveshaft and tailshaft and get the governor assembly out in a very confined space, clean it and put it back together. Probably $600 at least. There is no guarantee that this will fix the problem. Further troubles could lurk in the valve body, or other pieces that very few mechanics actually understand.

So you could easily go down the road I went with my 380SL. Diagnosis by Don Pool - $396. Rebuilt valve body - $300. Trans service and synthetic ATF - $225. Total - $921. Results - 0. My point is that instead of paying $600 or so to try the governor repair, you might be better off with a $1195 rebuilt unit from Adsit and a $600 R/R charge and be good for the next 100K miles.

I would try MB Motors for a diagnosis and look at the linkage and possible adjustment. If the problem persists, ask their opinion on a fix vs a rebuilt unit.

Good luck - this is s a tough one.
