re: chevy trailblazer 2007
Between 1,000 and 2,000 rpm (only 20% of the time) I hear, and feel, a clunk that seems to emanate somewhere near / behind the driver seat. The error code (an 834 ? possibly but I forget exactly…but def in the 800 series) says " transmission component slipping".
Trans oil full, and clear.
The clunk sound happens on any terrain, and is very random. And going up-hill does not bring it on. The clunk’s been happening for about 2,000 miles.
The orig transmission was replaced 15,000 miles ago.With a used one. Total mileage on car now 75,000.
Mechanics give varied explanations, and prognoses (none are good) but no one knows what’s going on for sure.
What’s your thoughts?
