Trans/converter isn't shot, only 70K miles on it and fluid came out ok. Check out LS1.com and a few other sites and you'll see that Mobil 1 isn't good in any GM Hydramatic tranny, which the 4l60/80e are. Joe

Well my 95 4L60E thats mated to a 4.3 V6 has some torque converter shudder, anything I can/should do to cure it, fluid or addative wise?
