i have a 4t60e im afraid to say, would like a 4t65e but oh well, where exactly r these aftermarket parts for my tranny? i wouldnt know where to look since the grand prix stores online i know of only sell parts for the 4t65e
on the subject of this thread though, the '97 grand prix gt's only about 10% had the 4t65e's but '98+ all 3.8 grand prix's i believe have it now, dont know how different the numbers for the regals might have been though
