Blowing oil out of trans?

[Kenny Wigington]

Mine has done that. Once with standard dipstick, and last time with locking dipstick. Both were because of having almost 1 qt too much in it, and having the vent clogged. I thought case was busted last time. Drain the trans, refill and mark the new dipstick, with a notch on it, to new full mark, and run it 1/2 qt below that, at most.

"Thinkin with ya dipstick !" Right Jeff ?!
