Help guys!
My 71 mustang has a C6 auto transmission. Nine months ago I ramped her to do some maintenance work. I did a transmission flush (7L of ford ATF) and changed the filter. I put in a Transgo 67 1-2 shifter kit too, a new vacuum modulator, a shorter pin and turned the adjustment screw a few turns in. She stayed on the ramps as it was then very wet here and coming up to winter. I was also waiting for a new, correct style exhaust system from the USA which took a while. Fitted now. I then removed the shifter mechanism from the car to insert new bushes into the lever as the action was very sloppy. That's done too.
Problem though now is that she will only shift from Park to Reverse but that's it. Won't go into neutral or then drive.
She fires up so can't be anything to do with the neutral safety switch I believe? And the shift kit, vac modulator and pin should only make a small change in the revs she changes gear at anyway? The shifter mechanism by itself is very smooth with no free play.
Thoughts anyone please! As far as I can remember I cycled the gears when I changed the transmission fluid and she has been dry stored in my barn since. I can't figure out why she won't go through the gears now.
Cheers
