i have a 1997 1/2 regal gs 3800 series 2 supercharged motor...milage 112000../ tranny was slipping in first gear...brought the car to buick(have aftermarket warranty)...buick sent car to aamco...picked up car from aamco and have had nothing but trouble...at first tranny had real soft shift, brought it back to aamco they said valve body gasket was no good and replaced...after a few days had more problems...no 4th gear or lockup and car was hanging in 2nd gear around town...went back to aamco and was told there was low voltage to tranny from engine which affected shift...picked up car again to have the same problem but worse, service engine soon light came on, had the mechanic check the code and was told it was o2 sensor.....i have not brought it back yet, and am afraid they will cause more damage to my car...all documentation i recieved from aamco suggested my tranny is a 4t65e i know my tranny is a 4t65e-hd, used for L67 motor...can anyone tell me the difference between the 4t65e and the 4t65e-hd transmission? i heard 4t65e-hd has a longer valve body shaft, is there any difference w/ the gears or clutches or torque converter?
