What happens if you put in too much tranny fluid?

According to the '03 service manual:

"DIAGNOSIS AND TESTING - EFFECTS OF
INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air
along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal.
If the transmission is overfilled, the gears churn the
fluid into foam. This aerates the fluid and causing
the same conditions occurring with a low level. In
either case, air bubbles cause fluid overheating, oxidation
and varnish buildup which interferes with
valve and clutch operation. Foaming also causes fluid
expansion which can result in fluid overflow from the
transmission vent or fill tube. Fluid overflow can easily
be mistaken for a leak if inspection is not careful."

SMACK!

Well, I got the long Mercedes dip stick and the ATF fluid along with SIKWANS fluid filling instructions and now I'm afraid to try it out. I even bought one of those little replacement filler caps!

:hmmm::cry:
