4L80 swap guys
4L80 swap guys 4L80 swap , what did you do for a Trans mount in your ride? Shim or no shim?
I have a crazy harsh vibration after the 80 swap that wasn't there with the stock 4L60 or the TH400 w/ brake. 98 Z28 in sig.
Only after the the 80 swap has this vibration popped up, same torque arm as the TH400 and the same Moser 12 bolt as all the transmissions.
Driveshaft was made by a local shop that's very good at what they do.
Any info you can share will be appreciated , I can't take this beast on the highway it's so harsh.
Thank you in advance

You think the angle changes from the TH400 it had to be 4L80-E? I can get that checked . That's somewhere to start , thank you .
Check your pinion angle and get that straightened out if necessary then if it's still doing maybe have them re check the balance on that drive shaft. It could be off a little.
