Selinoids in truck replaced. resets using battery disconnect in past. Flash codes indicate a host of related failures from something VSS buffer??? or R W AL BRAKES ???? TRANS SENSOR??? DIFFERENTIAL SENSOR??? Truck has 160k transmission was replaced with a jasper before I owned it. former owner had ABS ground wired to plow lights. Should i stop trying and take to the dealership for diagnosis????

If you like large bills with no fix, sure - the dealership will be perfect.

 

What solenoids are  you talking about? Transmission? Under hood fuse box?

 

What is the problem you are having? Speedometer not working? Service engine light on only?

Inside transmission pan shift selinoids were replaced. speedo and rpm gages flat will get me around in like 2nd gear. I replaced eprom box. a while back . temp fix then same as shift selinoids. it seemed to get worse over time. the frequency and not resetting itself after battery unhooked. thanks you.

I'd be looking all around the transmission for broken, or chaffed wires, green crusties inside connections, or bad powers & grounds to the TCM. Also make sure the VSS wiring isn't shorted to ground, or internally shorted.
