First check and confirm transmission fluid level, any brunt smell to the fluid.


Any repairs done to the car lately, No OD in that transmission 4th is 1: 1 ratio. Check for a stuck on kick down switch under the gas pedal, Black plastic round piece, push the switch down with your hand it should move and CLICK, when released should return to its off position.

Next possibilities, out of adjustment/ stuck, Bowden cable/ Transmission throttle pressure cable located in the engine compartment on the throttle linkage.
