Weird tranny vibration When I first started looking into the problem the car would vibrate excessively at 90-105 with 3.42 gears. A while later I put in 4.10s and the vibrating came down to 80-95 mph. The wheels, axles, and driveshaft were balanced and found out the driveshaft was twisted. After I got a new driveshaft and switched back to 3.42s the vibrations are now between 75-95. Does anyone have an idea as to we're the vibration is coming from??

What kind of driveshaft are you running? I had a LT1 (steel) driveshaft and it vibrated horribly! I switched to a LS1 (aluminum) driveshaft and the thing is perfect! Maybe that is your problem. LT1's had some problems with the driveshafts coming out of balance some how. All my weights and everything were still on and it was so bad it felt like the car was going to shake apart at around 100-120

Chasing about the same thing,gonna replace the differential bearings in one of the next wks cuz it seems like I have a lot of wheel play!! Hopefully that'll cure it once and for all!!
