904 with Turbo Action shift kit, no 3rd

first thing is check your throttle pressure linkage..also called kick down linkage...if it not adjusted correctly it will not shift into 3rd...

simple test...remove the linkage at the carb..and drive the car around the block...the transmission should/will shift really quick from 1-2 and 2-3....if it shifts into 3rd the linkage is not adjust correctly...
