Hello,
I have been a Chevy guy for many years and I’m 99% sure I’ll never buy another one because of the last 12 months.
Main reason for this post is to let you all know if you have a Any Chevy, GMC, Cadillac... etc. truck with the DOD AFM (displacement on demand Active fuel management) Have it shut off NOW! If you don’t know what this is it is a feature on GM trucks that cuts the engine in half down to 4 cylinders under low load via the lifters on the valves.
You can go to any shop and have it tuned off. This will avoid the following.
First of all before I get to the DOD bullshit the new GM digital 6 speed transmissions suck. If you think you can go the recommended 75k between services your wrong. Go every 30k.
Last August at 115k on my 2015 Silverado the transmission exploded. I had done a full service at 70k. POS cost me $4800 for a new transmission.
Then in February at 140k my motor blew a DOD lifter and it smoked the cam shaft costing me $9000 for a new motor!
Now this August my wife’s 08 Tahoe at 147k blew a lifter and it smoked the camshaft as well. Seeing as we owned the truck I decided I was not paying anyone again to do this as I know I could. I pulled the motor and did a full DOD delete on her truck. Lots of work but at the end of the day it only cost me $1600 and a few late nights.
If you have one of these GM vehicles I highly recommend you Google DOD failures or DOD Delete and get ahead of this costly know issue with these LS motors.
