my car has been sitting for a good six months because of engine problems. well i just got her up and running again. the car is a 700r4 with a transgo shift kit setup for full manual shifting, so there is no need for a TV cable. anyway, i took it for a ride the other day and shifted into 2nd gear fine, but when i went to 3rd, it stayed in second. i had to put the shifter into OD then pull it back to 3rd for it to work. i havent checked the fluid level yet, but does anyone have any clue whats causing this?

 

Plugged passage maybe.
