Sounds like you got the pesky torque converter lock up. take off your valve cover and check for hamsters. also flush and replace your headlight fluid....:)

just joshin ya. but yea sounds like the torque converter is just locking up and putting you in granny mode.

Do the unlock mod and see if that helps at all. it will allow you to pull andpull and pull.
