Question about GMC Cars & Trucks
My 2005 GMC Yukon just started this week hesitating when the transmission is shifting into 2nd and 3rd gears. The check engine just came on today, so I hooked up a code scan reader and it came back with code (P0757 Shift Solenoid B circuit stuck on). What do I need to do or buy?

The Shift solenoids are located in the transmission oil pan. I would recommend replacing both shift solenoids while you're in there. Also replace the filter and pan gasket. The shift solenoids are located towards the rear of the valvebody and will be identical to each other. They are held in place by a retaining clip which is easily removed with a small screwdriver or similar tool. Care must be taken as parts may fly out of the bore when the solenoids are removed. Hope this helps.
