the pancake dude is full of bubblegum...just kiddin.
there is an issue with the 540 transmissions, there is an upgrade to the valvebody that is available from ZF transmissions "Kurt Kohller". (800)624-3876 ext 5735 or direct at (616)748-5735 )
thats the first thing I would recommend, 2nd is not to cheap out on the fluid that costs like 10 bux a quart, people have used other and sweared it works but most have dissaperred since.
Dont flush the trans, your askin for trouble.
