i have a 1992 Mustang LX with a turbo 4. It has a 4 speed auto. I am having a problem with the shifting. It dose not slip in any gear or have an problems shifting into any gear but 4th (or overdrive). No matter what i do i will not shift. Could it be a computer chip?.Any help would be great<edited><editID>tootasf_2005</editID><editDate>37892.8381365741</editDate></edited>

 

Its probalby your clutch. I would have it looked at. Try some Lucas for the transmission that might help to. its only 7 bux. hope this helps.

 

Since when do newer automatics have clutches? They don't....they have torque converters (lock up to increase gas milage)
