2001 ford f350 7.3 diesel automatic transmission started no drive or reverse

SOURCE: transmission problem with 2001 Ford Escort

Sounds like a problem with the shift interlock.Here's how it works:You put your foot on the brake pedal,the brake pedal switch sends voltage to a solenoid mounted on your shifter.The solenoid unlocks the shifter,and you remove it from Park.When the interlock doesnt work,it's usually the interlock solenoid mounted on the shifter malfunctioning,however the brake pedal switch,or wires to and from can also be at fault.

this is the speed shift solenoid and a possible faulty transmission filter as well. the best thing for this issue is to pull the tranny and check for filter clogs and change the shift solenoid.

how too check transmission fluid on audi 100s 1994

SOURCE: 2001 Ford E250 transmission has no reverse gear,

I would check the shifter and the linkage. Even though the shifter lever is moving, that doesn't mean it's moving the linkage on the transmission.

about 15 if you have a flush machine do it. If you do a drain and fill you'l only drain about half of it out. so your not really gaining anything by doing it yourself
