ATF LIGHT 89 LC (1 Viewer)

[Captain Ron]

Had a major transmission failure which activated the ATF temp light. Had the trans. rebuilt and a new ATF temp sensor installed.
Transmission works great now but the light is on always. The rebuild guy says it is electrical and not his gig. I see what looks like a small circuit board in the shift box on the floor where the light is. I cannot find it on any wiring diagrams. I'm guessing this is my problem. Is it replaceable ? And how does it come out ?
Thanks

I had a rebuilt trans installed last year, obtained from one of the top suppliers on the forum. Same issue. Installer took the harness off my old trans and swapped it out. Problem solved. Sent harness back to supplier, never got an answer as to why...
