Hello,

I changed my engine out for a lower mileage 2JZGE and now I'm getting a whole car vibration in 1st gear on acceleration/deceleration from idle to 1100RPM. It's a W58. Doesn't happen in neutral. Also happens in 2nd but is less noticeable because less torque applied / gearing.

Only things I can think of -
1. Does the drive shaft have to be connected back on the same rotation that it was taken out of in the center? I know it definitely does on the side with the rubber insulator / propeller, but what about just the 4 bolts in the center split drive shaft area?
2. The engine mounts are Supra NA mounts instead of SC300.
3. The trans mount is new and was put in before the engine swap.

Do you have a pilot bearing installed? Also, yes, you should verify that the driveshaft halves are bolted together the same way as they were before. The u-joints should all line up. Finally, Im not sure what kind of mounts the NA supra uses, but the encased turbo mounts make for a good bit more NVH over the lexus parts.

check the flanges on the transmission and make sure those are super tight.. also as mention, check the driveshaft and makes sure the u-joint line up correctly with the yoke. also check the u-joints itself if its tight and not wiggly. its not lifted or anything, so you can eliminate drive shaft angles..
