Governor may be stuck ? You can remove the round cover off the side of the trans. I beleve it is the driver side.Pull the governor out and make sure the gear is not damaged or the valve is not stuck.To check turn the gear to the up position.Squeeze the two weights at the bottom, you should see the valve move freely inside,clean and try it again.How much oil do you have in it ? Will hold 8-10 qts if the converter was empty.Good luck.
