After the cam install I now have trans slipping in 1st & 2nd gears. Third seems to hold. It drives fine under 3k rpm, if you get on it above 4-4500 it slips, it seems to grip & then slip but once it hits 5-5500 it will slip up to the shift point. Just had the fluid changed & checked it tonight (was fine), reloaded the tranny tune but no help. The tranny was fine before the cam install & has about 300 miles on it since the cam install, 60,000 on the tranny. Any ideas what this could be? Wifes gonna be bent if I have to rebuild the tranny now!
