Re: 7747 vs 8062

Do you have a shift light on the dash?  When does it turn on?  Any
signs that the driveability is off or that the engine responds poorly
after downshifting while coming to a stop?

Auto trans calibrations in a manual equipped vehicle are usually
difficult to drive, but the same is not always true of manual cals in
an auto trans app.
