I ordered and tried to install a RWD automatic 3. 9inch deep cast pan from mopar performance parts. DC parts man ordered p#4876444 and stamped on the casting it states P4532881. This will not fit on my GDB coded transmission. It is too tight on the left side. Has anyone installed one of this pans? Should P#4876444 fit? The pan is well made. Any info on this subject would be appreciated.
