1989 f-350 idi E40D transmission
Could anyone tell me if my computer is bad? My tach is not working, and trans only has high and low. (limp mode?)
I have done research, looks like 3 main components, Ecu, tach sensor, and speed sensor. I put in a new tach, sensor, and my speed guage works. This is the only other thing i can come up with besides wiring, which could be possible.
I have attached some pictures, any help is greatly appreciated.
(see the off color blue, and the brown)
