Sorry, I know this is an old post, but I didn't get around to flushing the tranny last year, so it's on the list for this Spring. I just wanted to see if it was necessary to drop the driveshaft to flush the tranny with kerosene? I just know that I may end up bustin' bolts or something to do this and I'd rather just do a flush for now. I did pop the shifter off last night, so it'll be an easy pour to get the fluids in, which is nice.
