Intermittent Hard Shifting
Hello,
My father has a 2007 uplander 4.9 with a 4t65e transmission and is having problems with the transmission. It is important to note that the problem is intermittent and only reoccurs after the vehicle is parked and then used again. When the problem is present the transmission shifts hard in the low gears and sometimes in the high gears. It is also important to note that he has replaced all of the solenoids and relays as well as the front spark plugs (the back ones were to hard to reach). If anyone has any idea of what could be causing this type of issue, I would be very appreciative to hear from you. Thanks
