Okay, my boyfriend owns a 2000 ford f-250 super duty and your prolly wondering as to why im asking about this instead of him ... well im more mechanically inclined then he is lol funny huh... okay heres the symptoms... turbo kicks in and out when it wants, more so when you've been driving a steady 70mph for about 30-45min , transmission acts up in 2nd gear, so at take off you have to drop it into 2nd then when at 30mph throw it into drive for you to.... well move at a decent speed lol..next off, the brake lights dont wrk, passenger side window has a mind of its own, you cant start the truck with the key, you have to start it with the solenoid using a screwdriver... yea not cool when its raining..., its an automatic so the shift column ( i think thats what its called) is slightly loose, so kinda tricky to find the right gear sometimes, and the steering column has slack in it..... give me a rough guesstimation as to what might be the problem.. im leaning more to mostly electrical.. like in the steering column due to the fact its loose and fords are notorious for that or possibly a bad wiring harness....

It sounds like the shift tube bushings are worn out. There are usually 2 u shaped clamps that have nylon bushings that hold the shift tube to the steering clumn. If loose, that throws off the shift position, could be btween 2 gears at once, and throws off the park - neutral safety switch. Fix that first.

I have a 2000 F250 superduty 7.3 Diesel. I had the same issue with the horn blowing and then stopping if you opened the door. I was told that Ford trucks had a issue with the windshield not being sealed and the water would run in and end up on the GEM module shorting it out. They told me to get the windshield resealed and let the gem module dry out. Just depending how much water got in the module you many have to change the complete unit. The GEM module is located on the back of the fuse panel so if you have to change it you must remove the fuse panel and the two wire harnesses at the bottom to get it out. This unit controls shifting, security system, lights, Horn etc
Hope this helps
