What tranny comes stock with a 93 Buick Roadmaster? Only thing I can see on the ID plate is DRM.


Asked by Sep 20, 2014 at 10:47 AM about the 1993 Buick Roadmaster 4 Dr STD Sedan

Question type: Maintenance & Repair

I needed to replace front seal, O'reilly said it was the 700r4 and I used the seal they sold
me, but after reinstalling the tranny the thing is still leaking profusely out the front from
around the torque convertor shaft.

OK, I had some conflicting information, but the 4L60 and 700R4 are the same transmission. Now this is copied and pasted -----:1992 was the last year of widespread usage of the 700R4 (4L60). 1993 Camaro, Corvette and Typhoon were equipped with the last production 700R4's. In 1992 electronic controls were added, and it became the 4L60-E. The 4L60E went into service in trucks, vans, and SUVs in 1993 and in all RWD passenger cars
