Hey guys, i bought another used K2 recently. This one is a MY 2014 4x4 with a 5.3L mated to the 6L80e. I have been driving it about 2 months now and about two weeks ago when slowing down into a 35mph zone in town, it downshifted at 35mph to 1st gear which jumped the motor to 3,500rpm, threw a CEL and would not shift out of first. Thank my lucky stars I just happened to have my scan tool with me. So I pulled over, scanned the truck and got P2715, pressure solenoid D stuck open. This means a shift solenoid was stuck in the open position and would not let the transmission shift out of 1st gear. I cleared the code and it flashed the solenoid and the trans operated like normal. Checked the temperature, level, and quality of the fluid at home in the shop and the trans was at 75 Celsius (170F) at the time, right on the full mark, and still reddish in colour, not brown. Last night, once again, in almost the exact same place on my way to town, from 40mph, it downshifted to first screeching the tires and revving the motor to 4k in the process. Same code, P2715, same solenoid "D" stuck open. Again, I cleared it to get home (so I wasn't in 1st gear), trans temp around 165f. I have about 6 months left on my powertrain warranty, but have been reluctant to take it in because I have an immobilizer for work installed because we often leave our trucks run on the jobsite. I am willing to uninstall all this to avoid a fight with the dealer. Looking further, I can't find any direct info on this code related to the K2 series trucks. I have found info on the 07-13's having a cracked shift drum and clutch pack issues in the trans (which does not sound good) in relation to code P2715. The solenoid is located in the TCU/Valve body which is inside the oil pan of the trans. I have no personal experience working with the 6L80e, so I am wondering...Is it easy to remove the TSU/Valve body to change solenoid "D" if anyone has done this? Has anyone had the same trouble code on a 2014+ 6L80e? Any insight to help me make a decision would be great. Thanks guys.
