no light except when first starting and goes out rt away

 

check valve
been removed, some wiring repaired on tranny 3 wires going into valve body vertical bt neutral safety switch

 

I have an 86 W150 4spd with granny 318. Good trucks

 

Replaced temp sensor and they had spliced in the grounding part of solenoids for tranny operation. I will scab in to the PCM to see if it’s grounding path is good there. I’ll check the tranny loom connection. I think it had a poor grounding problem for the fools to cut in the circuits as such. The truck hauls *** when all plays together nicely. Thanks for the help on this.
