So how many of you have had engine lifter problems in Chevy trucks. My went out on my 2017 at 66,000 miles. Not under warranty. Replaced at Chevy dealer. Went out again 6,000 miles later and was under warranty. Has gone out again 6,000 miles later and under warranty from the last repair. I will now put in the module to keep it from shifting into 4 cylinder. But I talk so many people that have this problem with the Chevy engines. No doubt the only way to go is to add the $150 module to keep it from shifting but it is sad that Chevy is making such poor engines now. Jack it up and put a new Tacoma on it, LOL.

I had an 08 with 240K + on it when I got hit and totaled the truck.
I bought a Diablotune tuner and cut the AFM off at around 80K and never had a problem.
Never had an trasnsmission issues either.
In fact the only problem I had with that truck was the fuel evap purge valve.
I was on my way to get that when the idiot hit me.
Keeping the trannys cool is the key to their longevity.
I'm now driving an 18.
It's out of warranty and I have cut the DoD/AFM crap off on it too using the same tuner.
Just glad bassmaster95 didn't buy it when I offered to sell it to him when I was driving the duramax ... lol
About to add the trans thermostat bypass to it too to make the trans fluid run cooler
Oh, and anything with the AFM/DoD is subject to having the same problem. It's not exclusive to GM
and another Oh yeah, change your oil...All these new vehicles with variable valve timing - I'm looking at FORD owners in particular - use oil pressure to adjust the cam/valve timing.
if that system gets too clogged it can throw the timing off. This. Turn off afm as soon as possible. Change trans thermostat and increase shift pressures on torque converter. This can all be done in about 5 minutes with the Diablo tuner. Except the trans thermostat. That takes about 15 minutes.

I just tore down my 15 Tahoe because of this. Ordering parts this week. Does anybody have a contact in the hoover/pelham area that does the programming part?
