Curious on what this may be? Once shifting into 4th gear and sometimes 5th as well there is a lound clunk/thump type of noise around the floorboard. I'm unable to tell whether it's the front or rear area. It would seem that it's a transmission issue since it seems to be gear related.

Any thoughts?

This noise occurs once the clutch pedal is released back up and from what it appears not durning actual shifting into gear with the shifter.

 

turn your radio up.
then if it breaks get your tranny rebuilt

 

ya it's just things like this annoy the hell out of me!

gonna flush the tranny fluid and bleed the clutch and see if that changes anything
