Consumer Reviews for the GMC Sierra 1500
Read recent reviews for the GMC Sierra 1500
Rethink the 8sp trans.
Don P, 06/21/2018
2018 GMC Sierra 1500 SLT 4dr Crew Cab 4WD 6.5 ft. SB (5.3L 8cyl 6A)
18' GMC has the best looks, ride is good, stability in wind is amazing. I love the comfort and they made the cabin very quiet, road noise is not noticed. That said, the 8spd trans clunks, bangs 2nd to 3rd to 4th. Under throttle I hear no issues, city driving idling along, say 10 15mph, roll on and off the throttle and there are serious bangs going on, up and down. Its reminds me of a old … drive line ready to spit u joints at any time, its not in the rear end(ring n pinion lash), seems to be in the tranny. I have parked the truck, sits for +-2hrs, level, on start up the rear tires jerk the truck hard, defiantly gets your attention. Does this about once every 10 15 start ups. Took to the dealer and of course they say there is nothing wrong. Do your homework, look on social media about the 8spd trans, they are a problem. Buyer beware. Such a shame, love the truck otherwise.
