“My truck has 69,755 miles when the transmission went into protection mode. Jerry smith garage of anacortes wa. Found loss of prime of fluid due to poss sticking lube regulator valve in pump cover. This was at cost of $5849.87 I feel that this truck a 2500 heavy duty trany should last longer than 69,755 miles. It was being driven on the street”
NHTSA complaint #11063576, filed 2018-01, 1 miles“My truck was diagnosed at the dealer with all of the transmission cooler lines leaking, at the crimps. Nearly everyone I know that has a 2007-2009 has had the same issue. If undiagnosed, this could lead to transmission failure due to fluid loss, loss of pressure, etc. Clearly a manufacturing defect, no diagnosis of cause due to elements or driver error, etc.”
NHTSA complaint #10447363, filed 2012-02, 44,000 miles“I have replaced transmission cooler lines twice (2 times), since purchasing this truck with 59k miles on it. Both times with AC delco parts. Both times the transmission cooler lines leaked, not an installation problem. 11/21/13- I first noticed it when driving at 25 MPH picking up my kids from school, and I had transmission fluid spraying out from underneath my truck, causing it to smoke/smolder on my exhaust pipe. (transmission fluid is flammable). The crimp has separated from the hose. This is the first time I replaced with genuine GM parts. …”
NHTSA complaint #10667383, filed 2014-12, 61,500 miles“2008 chevy SILVERADO 2500, gas engine, 34,600 miles. Transmission is having issues that dealer cannot seem to fix. New pump put into trannie, still having problems. Usually happens in tow haul mode, hauling approx 5,000 lbs. Transmission will not shift up, holds and revs to 3500 or 4000 rmp's. I take foot off gas and it bumps into gear. Most often happens at 35mph and 55 MPH. When slowing down transmission slams into lower gear and revs very high. At 55 MPH on I-435 in kcmo during rush hour, trucks tires locked up and squealed when trannie down shifted. Has a major issue between 30-40 MPH. …”
NHTSA complaint #10352345, filed 2010-08, 500 miles“This is a 2008 chevy silverado hd z71 4x4 well taken care of. And the transmission goes into limp mode on fast stops. This is extremely dangerous due to the fact that if a load is on board and it goes into limp mode this could be dangerous for all behind the vehicle and around. Which could be a threat to all unexpectedly causing undue harm to other while in control of this vehicle. And vehicle sends out a code.”
