full motor mount install.... now have knocking sound

[peter_parker8740]

Well I have all my cp-e mm installed. Had the rmm and passenger side mm in for about 3-5 thousand miles on each. Finally installed the transmission mm last week. I now have a knocking sound when shifting from 1st to 2nd in high rpm. Before its asked yes they are all torqued to proper spec and none of the bushing are bad on the mms. Any thoughts to what else it could be ?

Thank you for your time

I can't speak for having all mounts but when I installed my stage 2 rmm from cpe it didnt take.long for me to notice that since I had to push the Engine forward to install it I had no idea until later that it seemed to keep the bottom of the engine pushed forward inturn I think pulls on the exhaust I looked at my exhaust which is cpe catted Downpipe and corksport three inch catback and found all hangers are pulled forward if there is a solution I would like to know what it is. Not sure if this is what you are dealing with but my exhaust was hitting on the center cross member and at the first turn

Is this with your foot on the clutch? Or before/after engagement?

My story is similar, I'm putting my JBR side mounts, first the TMM till I become used to the noise. Anyhow, after installation I experience what I find to be similar to your description.

I would say it's normal it's normal if the bolt is seated correctly and all the adjacent bolts are tight.
