Hi.. I have a GHIA with a 5 speed automatic transmission w/ SPORT/NORMAL and O/D....
From one day to another it stopped going any further than 4th,it is possible to switch O/D on/off, but nothing happens other than it HOLDS the gear in when letting go of the throttle slow down.
When starting.. moving the lever into "D" og begin to give light throttle as a normal acceleration, it will only change from 1st to 2nd between 2500-3000 r/min IF I let of the throttle a bit and give it a chance to shift, and then it shifts to 3rd-4th as it always has. If I dont let go it will keep revving.

All this happend over night

Anyone knows anything about this??
