Welcome to the Chevy forums.
Yeah, been here, done this.
What you're dealing with here is a transmission ignition interlock solenoid.
All they do(Supposedly, that is, besides aggravating the crap out of the driver)
is lock up the tranny in the event somebody tries to shift the car with the
YUP, the weekend, YUP, extremely inconvenient.
It's a dealer part, so what you do is have a mechanic take it out, then do the
right thing, LIE.
Sweetly smile, say "May I have that? I can't wait to go to the dealer and
spend 238.79$ special ordering one of these beauties! I'll bring the new one
ri-ight back for you to replace it."(CAR RUNS FINE WITHOUT IT)
Then drive away. Once you're out of sight, THROW THAT POS RIGHT IN THE
We did, and the car never ran better. And we've never been happier.
