I want to confirm that my auto-trans is running at overdrive. Please clock and let me know the correct RPM at 60 and 70 MPH. I want to make sure my trans is shifting correctly all the way to top. The ratios of 4 to 5 gear is small viz. .87:.7, so you wouldn't notice it unless somehow the ECU is tied to it!

    Hey, Heb, this should help you (assuming you have a turbo 850): Third gear Ώ.37 ratio] gives 20.1 mph for every 1000 rpm. Fourth [.98 ratio] gives 28.2. This is with the standard 2.54 final drive.
