This sounds wrong. It should be about 3500 to 3600 at 70 mph. Tachometer
may need recalibration.

Works in 2nd, 3rd and 4th, but not 1st. Not really 7 forward gears: OD 3rd
and 4th are very close. You can drive around the suburbs in 3rd and OD 3rd
and on the highways in 4th and OD 4th without changing gears as often.
