Suburban / Tahoe third brakelight
Celerity posted a topic in 1999-2013 Silverado & Sierra 1500I'm working on an issue in another thread, but I came across something else that I thought might deserve a dedicated thread. I've been poking around in the rear heater lately, and then I went away for a bit. I guess I didn't connect the third brakelight connector. Anyone know where this is ? I've been looking, can't seem to find it. I'm sure I did something to knock it free or disconnected.
Tarnold posted a topic in 1999-2013 Silverado & Sierra 1500First time poster here. My son's 2007 GMC Silverado single cab, 2wd automatic started having issues last night. He was taking off from a stop light turning right and lost the gear. When in Drive, it does nothing. When manually shifted into 1st it takes off fine. When shifted into 2nd it takes off fine even from a standstill. Shifting from 2nd to 3rd manually will not happen until about 20 mph (could be prevented by the computer). You can manually shift thru all of the gears and get up to speed. When I shift from 2nd to 3rd the engine revs as tho in neutral then slowly catches the gear and engages. I can shift from 3rd to D and it will do the same thing - rev and then slowly catch the gear and engage. I have an OBDII reader but nothing is coding. Don't know if I have given enough info here or if I even sound lucid but I would appreciate any help! Thank you!
I messed up on the rules a bit for posting on the vehicle builds thread. I have re-started this at this link (has my username in the title now): http://www.gm-trucks.com/forums/topic/193187-endurante221bs-silverado-1500-3rd-gen-modifications-to-consider/
