Sounds like the transmission is slipping bad-How's the transmission fluid level and condition if okay -bring it in and have it further diagnosed by a tranny specialist

Hyave you tried manually advancing the gear positions 1 2 d? That's an electronically controled transmision so the problem is likely the range switch or soleniods on valve body. But check the kick down arm that is hooked to throttle also.
