WOW !!!!!! JGL1 THANK YOU.....VERY HELPFULL INFO.
if i attemp this at home( i have changed trans fluid on another 97 e320 before).... what about clearing the codes when i have replaced the parts. from what i can understand from other posts is that even if problem fixed still nead to clear the codes....hmmmm maybe i can get the shop to clear it before i tow it.
P.S: CAR HAS DONE 84000 miles and fluid has never been changed. nor sure of metal color etc... will check monday.
