In doing all of the routine maintenance on the new-to-me '04 DII I seem to have stripped the transmission drain plug (the allen portion, not the threads into the pan). Any advice on how to remove this without causing permanent damage to the DII (i.e. preferably not drilling it out)?
Already ordering a new one from AB.
Guess this means it's been a long time (if not ever) since service...
Since your dropping the pan anyway, start with a drill that just goes in the stripped out allen key hole. Then use a screw extractor and it should come right out without damaging the threads in the pan.
