P38A rpm and autobox

johnnysensi · Jul 26, 2015

Serviced my autobox...got smooth changes but only changes with high rpm....now I'm no p38 wise man but when getting to 5o mph I'm near to 4 k on the rpm,s then it changes gear on a flat road....same when touching 30 mph....this can't be right can it...

Sport button on?

Sports button is the same as it's always been..around 3 k rpm changes if I remember ..I don't often use it but this weekend I chucked it on and far less rpm to change gear than in normal gear...from 2nd to 3rd it fills like next gear up takes such high revs for to be correct timing..4 k rpm before it reaches 50mph change up

If it has to do 50 mpg before it changes up you are going to have a long wait.

Depends on how much throttle you are using. If you are on a down grade or an up grade. On the flat a heavy foot it will change later a light foot it will change sooner.
