The Band, not the Disease!
Hey guys, on my 97 mark VIII, it feels like 3rd is slipping. All shifts are quick and firm, just when under light acceleration or cruising, in third gear, it will raise rpms about 100 - 200 and then be normal, then raise again, in pretty quick succession. Car has 160k miles and as far as I know, the trans is original. Should I drain the pan and TC, clean out the VB and update the accumulators and fill it with fresh Merc V, or just put that 100 bucks into a new trans? Under moderate and heavy acceleration, there is no "slipping"... it's just under light throttle and cruising it feels like this. Any advice?
