long story short, I had my '00 f150 trans (4R70W) serviced back in Sept. at the dealer . this week it starts acting funny almost like it is slipping but not, just takes forever to get out of 1st then shifts hard to 2nd. So I figure low fluid right?, no the fluid in 1/2 inch up the stick above the plastic tag that says "do not add" .
Now I havent touched the tranny for this whole time. I call the Dealer he says "bring it down, we will look at it "" no excess fluid would not cause it to act this way", but this will be on my pocket if its broke 'cause I am 500 miles out of warrenty. the truck now has 725xx miles on it .

you mechanical wizards have any ideas on what is wrong w/ it ?
I am dropping it off for the look see to night, maybe I can do it myself if I know what is wrong w/ it .

Thanks and Regards, Roy
