2007 Chevy TrailBlazer Transmission Problems


Asked by Apr 26, 2016 at 08:45 PM about the 2007 Chevrolet TrailBlazer

Question type: Maintenance & Repair

My TrailBlazer is having a major problem.
When I put it into drive the RPMs fly but
the car doesn't even budge. It does the
same in Reverse and 123. I don't feel
anything when I shift and I read that ur
souppose to feel a jolt kinda feeling that
shows it locked in gear. But it's just
smooth shifting with no jolt. We took it to
the auto shop and he changed the trans
fluid and put a new trans filter on and it
worked great for 5 days then it did it all
over again. The transmission fluid was
unbelievably high. So I undid the trans filter
pan and drained a lot out and it's still too
high. I've tried everything and really hoping
it's not a internal problem. Please help if
you can. It would be very appreciated.

I'd take a prybar with me and pry at your transmission and possible engine mounts...these are fairly inexpensive to replace and the linkage is thrown off....and the thing don't work no more~ can shop for ya and post the link...but you maybe able to get this locally~


Could be the typical shift solenoid problem, I would have it towed to a good transmission shop and have them look at it, they can hookup electronically and test the solenoid functions to see if thet operate at all or if it is the TCM not sending the signals.
