included a table with several automatic transmission ratios in case you don't remember yours. If
you don't have a Lockup Torque Converter, then you will need to add an additional 200-300 RPM to
the chart numbers.
If you want to be dead accurate, then download the Excel spreadsheet file and fill in your particular

charts are done at 70 MPH.
