2006 chevy silverado hd diesel with allison trans-- transmission cooler lines leaking, dealer said there has been no known problem. I searched online and found hundreds of similar complaints. So I was forced to pay $700 to have the lines replaced, which will probably end up leaking again. This is obviously a defect, as I have 3 other chevy trucks, none of which have ever leaked from the trans lines, and some are over 10yrs old.
Transmission coolant line leaking.
Leaking transmission cooler lines. Lines consist of a flexible section swaged to section of hard line. There are 3 lines total. All 3 have a history of leakage where the flexible section swages to the hard section. This has been a very common occurrence reported by other owners which can be easily verified through numerous online forums. I. . Read more...
My Chevrolet 2500 has a function called grade braking to assist the brakes when towing a load down hill. It has quit functioning but the dealers cannot figure out how to troubleshoot the problem. They said since no codes show on the computer I have to wait until I have a trailer behind it and am near a dealer that is near a steep grade to test it. The whole point of the system it to keep the truck from running away on a steep grade. Doesn't sound like the place to test it. There are no steep grades with in 150 miles of me. There should be a simulated test run by their computer.
My 2006 durmax diesel 2500 truck has transmission hoses that run from the transmission to the radiator. These hoses have aluminum pieces on each end and they seep oil at the joint where the aluminum joins a piece of rubber hose in the centre. They continuously leak transmission oil on the ground at this crimp join. The colder the weather, the worse these hoses leak. I feel because of the damage this oil causes to our fish stocks and the environment these hoses should be recalled and replaced a Chevrolet's expense. To date so far, all attempts I've made to correct this problem, at kelowna chevy or head office have failed. They are now interested. Please give advice.
2006 chevy Silverado 2500 hd w/allison trans. Transmission leak. Took truck to deal, deal fix 1 out of 3 lines under warranty. 4000 miles after dealer fixed first line, 2 other started leaking, deal would not fix other 2 lines stating truck was no longer under warranty. GMC should recall the vehicle base on possible fire.
The allison automatic transmission cooler lines are leaking. This poses a fire hazard. Gm needs to redesign the hoses that connect the transmission and transmission cooler. Many others are having this same problem and have had the lines replaced multiple times.
Starting 4 days after delivery of this new light duty truck with diesel engine and 6 speed heavy duty automatic transmission, the transmission has almost continually malfunctioned, causing what I believe are dangerous conditions putting myself, my passengers, other drivers, and pedestrians at risk. The malfunctions include acting like in neutral when starting from a full stop, causing the engine to rev, and then the transmission suddenly engages causing the vehicle to lurch, similar problems at the transmission searches for higher gears, even at highway speeds; the engagements are so hard I believe I am at risk should this occur on low traction roads, or on curves. Most disturbing is that moments after coming to a full stop (foot off accelerator), the transmission suddenly (on no fewer than 10 occasions) sends a surge of power to the drive wheels causing the vehicle to lurch. I am fearful that this malfunction may cause the vehicle to be propelled into a vehicle in front of my, or worse, pinning a pedestrian between this vehicle and a fixed object. Also shocking is that upon the vehicle being returned to me for the 3rd time on August 11th, within an 1/8 of a mile form the dealership, as I approached a stop the vehicle wheels suddenly locked up for a moment. I returned to the dealership and the service manager drove the vehicle. He repeatedly duplicated the problem and experimented by shifting into neutral, shockingly, while in neutral, the transmission still seemed to engage the drive wheels as we approached a stop. Only 42 days since delivery, and the vehicle has been at the dealer for service for 13 days, and has also continued to malfunction while under my control another 12 days. I believe the dealer, auto manufacturer, and the transmission manufacturer (who is said to be providing direct instruction to the dealer on diagnostics and repair) are placing me and others at serious risk of injury.
