I have problems shifting unless I let off the gas also have a very hard time getting above 50 mph.

Seems to run a litter better starting out cold.

When was the last time the transmission serviced?

Could be a problem with the throttle position and vehicle speed sensors-these sensors inputs signals to the computer as an indication of throttle and governor pressure and in turn the computer activates certain shift solenoids to provide the upshifts/downshifts, lock-up etc.
