  1. Transmission Problems (TCC, Shifting)

    OEM Issues
    Hi All, For my first post here, I'd like to get some input on what I might be dealing with. I got my 08 Trailblazer LT (4.2) about a year ago, and ever since I've been dealing with the TCC intermittently locking/unlocking over and over, along with some other shifting issues. The TCC...

The top to our dipstick will not lock into the dipstick tube no matter what. Every time I try to lock it into place it pops out about a 1/2 inch and...
