clutch popping
 

ive been having a problem recently with my clutch falling out of fourth gear, if anyone can help and throw out some ideas itd be appreciated. ive searched but havent come up with many results with an aftermarket clutch. i had a cc stage 4 clutch and new ap1 flywheel installed at the beginning of the week. this problem never happened before but when i decel in 4th gear between 2500 and 3000 rpms i get clutch buzz harder than ever and the shifter pops halfway out of gear. everytime as long as i start decel above 2500 rpm. has anyone else experienced this after putting an aftermarket clutch in? i tried holding just the shift boot to kind of muffel it w/o forcing it in gear and it still kind of pushes out. every other gear has no issue and starting 1st ive gotten used to and never had a problem. a friend has stalled it but i dont feel this would be associated with the 4th gear popping.
also the clutch buzz occurs in every gear which i expected but seems loudest in 4th decel.

Doesn't sound good,u could try putting some premo tranny fluid in it and see if it makes a difference.Is that clutch buzz or tranny whirring? I'm guessing that is a high mileage tranny.Sounds like tranny problem,not clutch related.Year,mileage and history would yield more responses.Bent shift fork.

I had this happening with my 94 Accord a while back. Whenever 5th gear hit in the higher rpms it would pop right out of gear. Didn't have time to take it in right away and a week later everything locked up in rush hour traffic. Not fun. Had to have the car towed, and it ended up being the trans.

I had a similar issue with my Subaru. Bad synchros were to blame. Could be a shifter linkage issue, but either way it needs to be fixed

If you paid someone to install your clutch I'd start there.

this happened to me with 3rd gear, was a failed synchro, honda fixed it under warranty but did an unbelievably horrible job. have fun
