Tranny not shifting out of 4th gear...PLEASE HELP!

Last weekend my tow/haul light started flashing and the check engine light came on and the truck wouldn't shift out of 4th gear. The codes that came up are P0766 and P02703 both Shift Solenoid D codes. I just replaced the solenoid and put new fluid in, tonight, and it still isn't shifting out of 4th gear and is bringing the same codes up w/ tow/haul light flashing and check engine light on. I replaced the solenoid with the Direct Clutch Solenoid from GoGo Diesel through Holderdown Performance. I am at my wits end with this truck, instead of nickel and diming us is thousand and more thousandsing us. I keep my tuner set at setting #1 which is 25hp over stock and fuel economy mode, i don't beat it, I treat it damn good with only amsoil oil and fluids besides the coolant. Any input would be great. VERY FRUSTRATED right now.

Thank You!

Post what they find. Might wanna think about getting rid of the Mach7 and going with SCT and custom tunes to make new trans happy.
