have 1998 3500 2wd auto that is slipping pretty badly in first gear. I have never had a transmission problem and am going to begin searching old posts, but would love to hear my options. I plan on driving this truck for many years and would like to fix it the right way. Would love to do the swap to manual but the price tag of around $10,000 is to hefty right now. Have not updated sig in a while truck has 80k.
