hello everyone i have a 1993 thunderbird 3.8 non supercharged. I bought the car with no overdrive in it, and have heard they go out of alot of them. The car shifts fine 1 2 and to D but when shifts in to overdrive just revs and no go. Was wondering if these is something that happens alot and is easy fix, or am i going to need a new trans. Please help me out thanks
