700R4 won't shift up.... - Third Generation F-Body Message Boards

I have a 700R4 gearbox attached to my 305 Crossfire.

The box shifts keenly into reverse, drive,overdrive etc. But, it won't go up to 2nd, 3rd....

There is fluid in the box, fresh fluid too.

Is there a cable, pump, electric gizmo that could be causing it or is it time for a new box/rebuild etc?

is this a suddenly new issue? or is this a new car to you or new tranny install?

check the governor gear

while you have the gov. out make sure the valve moves freely. with the gear pointed up move press the butterfly weights and realese a couple times. if the valve doesn't move you have a hung valve.

I had that probleam once and it turned out to be my TV cable just needed to be reset. i would try that and see if it helps.

Just had this problem with my transmission. I replaced the governor gear and it fixed the problem.
