We have a non turbo automatic 2007 PT with 31,000 miles on the clock.
We have a vibration under light acceleration in second gear from 2000-2500 rpm.
Shift points seem fine and it doesn't vibrate (more like mild pulsing actually) in any other gear or RPM range.
The dealer has updated the control module firmware and has replaced two motor mounts they said looked worn.
At this point the pulsing sensation still exists but - still only between 2000-2500 RPM and only in second gear.
The dealer has been very friendly and seems to be genuinely interested in resolving the issue.
Any ideas ?
Thanks all
