Hi, I've been lurking in and out for a while,found a bunch of great info here. Been dealing with Jennings in Essex since my 93 now a 99. Got a price for ATS upgrade, full transmission rebuild is 5600, tc,vb,commander is 3700 hope to have enough transmission left to need just the upgrade. 92000 miles on this thing but mostly highway and light towing. First shudder happened on the way back from vacation, got home, got on the phone got a loan, got heartburn. JC at Jennings says 2-3 problem needs looked into while they're at it. Amsoil since new,warms up in neutral, no lugging in too high a gear, hope I've done enough to save 3 grand. Your advise and concerns welcome... . Mike
