Subject:Gear ratios? was: How to know RPM without a tach
From:Steve Selin

Can anyone tell me what the gear ratios are on a 1981 automatic?

Also, the chart I saw was specific for VW vans, so I imagine the gear ratios
were taken into account in the chart.  Anyone know the whereabouts of this
chart?

Thanks,
Steve
