Air bubbles in transmission fluid?

Hey all,

This may be a silly question, and I may already know the answer to it, but would the fact that I noticed a lot of tiny airbubbles on the dipstick while checking the transmission fluid lead me to believe that there may be a leak in the system?

I did notice a little bit of a stain on my driveway, and have not been able to figure out exactly what it is yet, but I am curious if it could be transmission fluid.

It doesn't look like the fluid is low, as of yet.

Thank you for your ideas in advance! which vehicle is this?

the most common cause of this problem is a overfilled tranny, tho it could allso happen if the fluid is too low. it has to be thoroughly warmed up to get a good reading, and that can take 15-20 miles of driving. once its warmed up real good, cycle it thru the gears and leave it idling in neutral while u check the fluid. make sure its parked on a level surface.

if the fluid level is ok u could have a blocked tranny vent. If this is your Dodge Ram, make sure you are checking the fluid level with the gear selector in Car Repair Talk's forum.
