Matt and parrothead:
The more I think about the shifting complaint, the more I think it could just be the throttle valve cable for the transmission adjusted too tight. Worth checking if there is vacuum to the modulator, another simple check. Unless Parrothead is the original owner of the car, I kinda doubt the trans fluid has never been changed (possible I guess, but doubtful). It should be done every 30,000 miles though, so if you know it's way over that,i'd get it changed.
