We have a 1990 Ford Bronco II that we just put a new transmission in hoping to solve our problem. It did not. The problem is the vehicle will not shift at all into gear. There is no park, reverse, or anything. It acts as if it's in neutral and just rolls downhill if it's not blocked. We put the new tranny in and that didn't help. It quit on us while driving down the road. We've checked the fluid level. WE even tried shifting it manually underneath and still nothing. Please tell us how we can make it work again asap! thanks!
