my instrument and fuse panel is shorting out and causing my transmission to act up. I had this problem a while back . My tach , gas and speedometer quit working and transmission stayed in 3rd gear. I started checking fuses and noticed when i did that when i touched the fuses the gauges would flicker and like theres a short. i got them to stay on and the transmission started working fine. It worked good for about a year. and just now it started doing it again. but it seems worse now. i stop the truck and turn it off wiggle the fuses and it works for a little about 1/4 mile and then starts to not shift at all. does anyone know what the problem is? thanks

 

Bad connection to the fuses in the fuse box. Find which fuse it is and then get small needle nose pliers and try to tighten up the contacts in the fuse box for that fuse so that it makes a better connection.

What year model? I would agree, you need to get to back side of the fuse box and find out why or what is loose causing the intermittent connection(s)....

 

Its a 2002. Would this be the problem to the shifting. I noticed when I jiggle the fuses it starts working again. So I can check the connection on the back of the fuse panel.

 

The electrical short could be causing mixed signals to get to the transmission and causing it to shift differently...it could be causing a voltage drop out and one of the shift solenoids could be that circuit... but yes an electrical issue could cause your transmission to shift differently...
