Question about 1991 Ford Bronco

1 Answer

My 91 Ford Bronco wont shift on its own, need to manually.

My 91 Ford Bronco wont shift on its own, is the neutral switch easy to fix? I believe that is what they called it. I was told this was previously cleaned and sealed with silicone; however, there was water in it when I took it in, so I am not sure if I have many options aside from replacing the entire switch and with zero knowledge on this subject I just want to make sure I have covered all my options. Thank you in advance if you have any ideas...

I don't believe your problem is the neutral safety switch, that is for not allowing the car to start in any postion, except for neutral and park. I think your problem maybe the transmission modulator, it is at the back of the transmission. It operates from engine vacuum, so it maybe bad or it's not getting any vacuum. If you pull the vacuum hose off the modulator, and you find transmission fliud in the hose, the modulator is bad.

I believe your Bronco has a 4x4 actuator which often fails. Not a cheap part, but pretty easy to replace. Buy a parts store shop manual and it should show how to fix this. Might also check wiring to the unit and all fuses.
