Transmission problem

Greetings

I have the next problem with the 3 -speed transmission (and I believe with Overdrive in the turbine) of a Plymouth Voyager model 97, the problem consists that when I go on the road it starts to throw the oil through a vent, the transmission works perfectly to my point of view they enter: the 3 speeds, the speed is not skated and the change is quick. The problem has been bought since I bought the truck, and thinking about protecting the transmission put an extra cooler, but the problem persists.

I am a mechanical technician but the transmissions are not my fort, I ask a partner who is dedicated to the repair of transmissions and told me that it was the turbine that was damaged because the overdrive was not entering causing the transmission temperature to be elapsed, but what I did not like was when I add that I saw that he repairs all the transmission this told me 7 months ago and all this time has worked well except the dump of oil. Have to repair everything.

Thanks for your answers.

When one takes out an automatic box to make a repair, everything is changed since it breaks in the kit and you make sure you never fail again

good
you already looked at the transmission oil carter ???
Does it have a square shape with a diagonal or rectangular shape?

Rather, what you mean with over Drive in the turbine is to the effect Lock-Up but that does not affect the temperature in fact that system can be damaged and you will never give yourself how much until the turbine disarm
if your carter is square with the diagonal, a change piston may be Fuling and the precion releases it by the vent
and if it is rectangular releasing precion for the eye breathtaking: but this transmission does not gut with Over-Drive only the first

note: the turbines do not probate this failure in any transmission; The turbines when they fail cause buzzing or getting completely off

I put some photos of the transmission lid and one of the vent where the strip.

Good
forgive for the delay but I was pfreguiring with several transmitionists and they all gave me the same response
that this breathless is closed and that you have to cover it because in high speeds it will be throwing oil and tells your transfers that it is not an idiot that this transmission does not have over-drive
