revving during 3-4 shift 4r70w
hi, i have a 3500rpm stall edge converter, with a PA valve body.
when i'm driving, the 3-4 shift always revs a little, about 500rpm. this is barely on the throttle. if i turn OD off and on, sometimes it will rev, sometimes it wont.
is this a major problem, or should can the chip fix this?
btw, never WOT'd the car yet, hasn't been on the dyno yet.
also, a little off topic, should the line pressure be raised even though i have the valve body?
