Guys,

Double checked the shifter is not touching the hole. No part of the trans is touching the frame or anything else except the mount. Eng mounts and trans mounts still tight. Driveline angels are; pinion = 0.9 deg up, trans = 0.5 deg up, driveshaft = 7.9 deg down. Driveshaft runout at the pinion end is .006" and the same in the middle. I couldn't get to the trans end to measure runout.

The vibration is not heard or felt; it is seen. The shifter moves back and forth about 1/4" and the speed is related to rpm. If I put my hand on the shifter I can calm it down some. This is in 4th gear only and only on accel or cruise. No shifter movement present on decel.

Wayne - did your shifter move as described above? Any movement on decel?

The U joints have no noticeable play. The car has 1000 miles so I don't expect a U joint problem. When I swapped yokes, I inspected half of the U joint that had to be removed. It looked like new and I reinstalled it with the new yoke. I did grease both joints on install.

The trans did slide all the way in without using the bolts to pull it in. That does not mean the input shaft did not bottom out.

I spoke with Kiesler tech support today and they suggested checking driveline angle and driveshaft run out.

I plan to call ERA and speak with Doug tommorrow and then decide on a plan of action.

John
