Note. All shift point values indicated in the above table are actual values. Therefore, if checking a shift point with a chassis dynamometer, keep in mind that there is a margin of error in the chassis dynamometer indication. If checking a shift point against the speed indicated on the speedometer, remember to consider the speedometer correction rate and margin of error in the tester indication.
