Didn’t want to derail the other thread any more than it already was so I’ll ask again here. What do you guys do for service? What intervals? Costs involved with it? Be honest, how long does your average transmission last? I’ll start first. I’ve had quite a few trucks in my somewhat short lifetime at 38 years old. All the trucks I have had were bought used with anywhere from 40-80k miles on them. By no means saying they are the best but all have been GM products. All of them have pulled heavy stuff all over the countryside and we put on lots of miles pulling a 20 foot boat and a 24 foot ice castle. I’m not proud of it but I can say I’ve never got a transmission service on any truck I own and I usually drive them until they have give or take 200k on them. The truck I have now, a 2500HD Chevy I got with 35k on it was the first one I ever had a transmission issue with. It completely fried just shy of 200k miles. I searched around and found a retired local guy that has been rebuilding the tings for ages and it cost me $2800 to get it taken out, everything rebuilt and new what needed it and put back in. To me it almost seems like paying insurance premiums. Is it really worth putting money into something that isn’t broke or just save up for when it does happen? Maybe I just have good luck? I’d like to hear what everyone else thinks and does?
I’m going back and forth on this right now with my 2015 Silverado. Have a 2000 Silverado that I changed the transmission fluid at 60,000 and no problems. 200,000 right now.
The 15 has 130,000 and friends are saying just leave it, truck transmissions are made to not be changed and you don’t want to disturb the metals.
Mechanic of course says to do it and offers tranny and differential drain as a package, or tranny flush and filter replacement. The lifters are supposed to go out before I would need to worry about the transmission? I did the tune to turn the cylinder deactivation off.
