I just installed new motor and trany mounts on my car , on the road test found it sounds like the exhast is louder and I have a stronger vibration throughout the higher RPM range , it vibrates in neutral and while driveing .
I feel like some how the engines not lined upor rubbing on the exhuast .

Has anyone installed new mounts and had this problem ? mabey its something I did or dident do?

Thank you

Is the tranny mount polyurethane? IF so, thats your prob. I have one in my V6 cmaro after the V6 hydraulic tranny mount took a dump on me. Everyone that gets in it, wants to know what performance mods have been done and mmany people ask if it is a V8 LOL

Put the rubber trans mount back in (its easy to change out) and see how it is.

 

I have poly tranny mount do you think thats the problem because if its normal i will keep it . I had all 3 mounts in my mustang and it wasent this bad of a vibration

 

Yup. If you still have the rubber tranny mount, try putting it back on. See if there's a difference. I won't be transferring my tranny mount over, I'll be using the rubber T56 mount when I do my conversion.
