1989 Justy 38,000 miles CVT. At 3500 Rpm while accelerating there is a driveline shudder in the car. Back off the gas somewhat, the shudder goes away then even back at 3500 RPM it is gone. If you cruise at 3500 RPM in D it is not there. When accelerating thorugh 3500 to 3800 RPM it is there. 3500-3800 RPM in Ds and R there is no shudder. Rev the engine in neutral no shudder. NO check lights are on. I may look at the brushes again but when I inspected them a few years ago they had very little wear (34,000 miles). I may change the CVT fluid but i think it is more in the clutch then anything else. Tis car is a blast to drive and I hope this isnt a big problem to worry about.

It happens at exactly 2500 RPM. Keep the car at 2000 RPM no shudder. 3000 RPM no shudder. Accelerate through 2500 rpm no shudder. Cruise at 3500 RPM and about 30mph shudder. Slightly back off the gas it goes away. Doesnt always happen.
