So out of pure frustration, I'm posting this in here, yes it's also under engine and trans, but it's an electrical issue I really need help finding, please!

here's the story, kinda shorthanded. 2000jimmy, 4.3 vortec automatic trans. Everything was fine and dandy when I purchased it, then one morning ABS and parking brake light comes on, speedometer didn't work and it wouldn't shift out of 1st unless I did manually. About 1min later, lights shut off, speedometer began working and it shifted just fine the rest of my work day. Til I left work. It all started again only it lasted longer this time. Like 5 minutes. Then all shut off and started working just fine. Now it is just stuck with the 2 lights on, no speedometer, and won't shift out of 1st.

I've looked inside electrical connectors, even if I thought it had nothing to do with it, I see no corrosion or water damage. No bad grounds. No blown fuses. My CEL isn't on so I didn't throw an engine code, so I don't think it's the vehicle speed sensor. I am about out of ideas here and just trying to get more eyes on my situation to maybe resolve this. Please guys, gals. Thank you

 

Nick,

I've followed your other thread. Research why insurance companies total flooded vehicles.

 

I understand why flooded vehicles get totalled, but this was a solid 4 or more months ago and I had it for a good month or so before having this issue. I feel like it's something simple I'm overlooking. Im not seeing water damage in anything which is why I'm kinda thinking this doesn't have to do with the water exposure, it's not like it sat in a flood, he drove through a flooded part of a road. Idk I'm ring to exhaust my options before junking it, it's my backup vehicle and I can't afford another. My toy needs a new clutch which I have just trying to get this one to act right again.
