They told my neighbor it'd be about 4k for his 8-spd. You sure your power train warranty is only 60k? It's not the same as the bumper to bumper... Mine is good to 100k and I'm at about 86. Sent from my SM-G892A using Tapatalk
Well, hopefully if it does come to that your power train warranty will cover it. Mine paid for a 4k AFM Lifter job about 10k miles ago. My transmission worries me a bit, too. I've noticed that if I get on it from a stop I sometimes get at least a full second of slip on the 1-2 shift. I'm worried it's gonna give up the ghost one day while towing my camper. Good luck. I hope the warranty covers you if the tranny is bad. Sent from my SM-G892A using Tapatalk
My neighbor has a 17 and says he has the same thing. He paid for some magical flush and it helped but they said if it comes back, that he'll need a transmission. Sent from my SM-G892A using Tapatalk

My first thought was u joint, but you said you covered that. You don't have anything rolling around in the bed do ya? ;). Sorry I'm not much help. Sent from my SM-G892A using Tapatalk
Did you have to change the cluster or anything? There's a note about that on their site saying that you lose the steering wheel controls if you don't.
If I remember the manual correctly it says you can change I to 4hi or 4auto at any speed. I do so all the time without issue. I don't always coast, but I'm not into the throttle either. Basically, just steady speed or off throttle and I've never had a problem. For 4lo, you have to be basically stopped or moving less than 1mph. The truck won't let you go into 4lo at anything faster.

My '15 has about the same mileage and the older it gets the more concerned I am about it's longevity. It's already had to have the AFM lifters on one side replaced and the y-pipe with the cats replaced. Both done under various warranties. I'm rapidly approaching the end of my extended warranty and powertrain warranties. I'm afraid the days of the 25 year old chevy cruising around are nearing an end.
Who knows? Could be where we live (hotter climates) or how we drive or just about anything. Mine didn't do it all the time, but it did enough to concern me ... Especially since we were shopping for a camper. Sent from my SM-G892A using Tapatalk
I recently had 2 cylinder's AFM system replaced. I've noticed in the couple months since that my mileage seems to have gone down a bit. It seems to go in to 4cyl mode just as often as before, but when it does many times the MPG gauge doesn't move. Other times it bounces back and forth between 18 and 24 like a clock ticking. It didn't used to behave like this. I'm driving the same roads. Also, (and I believe unrelated) I had the cat coverter y-pipe replaced under warranty a couple weeks ago. At least one core was rattling. I first noticed it after the AFM repair, but it might have been doing it before... I'm not sure. I'm just curious is anyone else noticed anything like that when there's was fixed.
