If the trans is over full it may cause it to slip do to the craetion of air bubbles. Is the fliud burnt or a brown color?

If your transmission is slipping then you need to replace your transmission. How many mileage your car has? Better to change your fluid and internal filter.

Fluid level does not go up by itself. Something got in there. Water? Antifreeze? Some oil change guy added oil to the wrong place?

Agreed...there is no "mystery addition" to the fluid level. I would drain and refill to the correct level, then report back.

I seem to have the same problem with my 02 silverado 208K miles, tranny starting to slip and fluid over level
also, fluid is reddish but not real bright.
When it rains it pours, when I brake when wheels turned left or right truck is hard to stop, pedal goes almost to the floor and the abs kicks in. One guy I talked to said he had similar problem and it was a cracked cylinder in the dual cylinder caliper. sound right? any ideas on the tranny. I have not looked at the calipers yet due I have 3 kids 5 and under and momma works nights.

Take it into a shop and have someone qualified look at it. The only way fluid will get in is if cooler in rad tank has a hole (coolant into oil and oil into your coolant) transfercase front seal leaking (but normally would overfill transfercase instead of going into transmission)

well if you really think about it your transmission is always overfull if you dont check it running and warm so there for if your tranny pump is weak it may show overfull not %100 sure just my two cents

trans is bad in my opinion due to coolant contamination, you will need a radiator too becuase the cooler is made in it, bonding material on the clutches break down from glycol in coolant, its the only explination for fluid overfull, SORRY!
