So I replaced the overdrive solenoid on my truck because it worked when I bought it a couple weeks ago but then it stopped after a couple days use. I replaced it just now and it still doesn't want to shift into overdrive. On another note my speedo is starting to jump all over the place which started before I installed the new solenoid today. It will stay then jump and when it jumps it moves the battery Amp meter and it dims and brightens the lights and it also flickers my left turn signal. I have no idea what could be wrong with it. My guess is the vss but what could cause those to go bad? Like would drifting on gravel roads cause it to get rounded off? but I don't know why it affects the lights and stuff.
