    Did I burn up my trans? Lets take a poll

    Had my transmission rebuilt around 3 months/4000 miles ago. This is the 2nd rebuild (260k on car, first rebuild around 100K miles). Went shopping and my ingintion switch went out, so I decided to drive home, around 20 miles in limp mode. Got the switch replaced. After switch replaced, its...

    Best place to get a 4L80E installed?

    Does anyone know of a good transmission shop in Central or South Mississippi that would install a 4L80E transmission in my 1999 tahoe? My husband recently installed a new crate motor in the Tahoe and we had a local transmission shop rebuild the 4L60E. It's going out again 6 months later...

    Transmission codes and limp home mode

    We tested Fuse 20 (transmission) and the white wire in the ignition switch. No power in the white wire. Just ordered a new switch, hopefully that will fix the problem. Here is the video below: I will post again once we get it replaced.

    Transmission codes and limp home mode

    Drove my 1999 Tahoe on errands this am. On my last stop home, cranked the car, then noticed the light under the PRND321 wasnt lit, along with the check engine light and the check gages light. Drove home slowly, after reading the forum, it seems like it is in that limp home mode. Got the...

    Driver Window wont roll down

    Surprise, window is working today. Maybe yesterday it was just having a rough day, we all do some days. I guess I will just wait now until it officially dies.... I did order a regulator/motor, but not going to disassemble all that mess unless it is really necessary. Thanks for all the...

    Driver Window wont roll down

    I don't hear the motor activating at all anymore, just dead. My first thought is to replace the motor and regulator with the one assembly. Then I started reading the other posts and second guessing myself with maybe needing to replace the switch.

    Driver Window wont roll down

    My drivers side window has stopped rolling down. Last week it was making a weird noise when it was rolled down and back up, it was a little slow. All the other windows work from the drivers switch. I have read the previous discussions posted, but it doesnt seem like there is a conclusive...

    60/40 rear bench gap in upper seats?

    I didn't replace the top covers, only the bottoms. So I never separated the top seat from the bottom frame.
