trans cooler

Thanks for all of the great info on the bypass for the trans cooler, I have never heard of one either. I also had not considered the moisture problem in the trans from running too cold. I have seen many tubes that are rusty, I just never put two and two together! That's why I love this board, I always learn something new. I also appreciate the different opinions and view points that others have.

Does this mean that the placement of the aux cooler either before or after the radiator cooler is over!? Or is this used when only using the aux cooler?

The thermostat completely bypasses everything past it. All it does is loop the output line into the input line.

As for how big a cooler is needed. That is a guess in any situation. Go the biggest you can fit and afford. Use two in series if you want to. The principle is like a big engine coolant radiator. The thermostat maintains the minimum temperature, the radiator size limits the max temp. If you have plenty, then the thermostat will keep it warm enough.

To answer your question: Why put heat into the radiator coolant if you don't need to?

OR..... leave the trans go through the radiator tank and then install the thermostat on the output line using it to connect an aux trans cooler. If radiator cooling is not a problem... that is what I do.

Hayden coolers recommends a thermostatic bypass if you operate in areas where the temperature drops to 20 Deg. to 30 Deg. below (zero) 0 Deg. ???

All irrelevance aside the subject here is not enough cooling and what is a figure to go by for enough?

.
Recapping: I mentioned that the dipstick was rusty above the oil level.

Yes it was Little Rock, Arkansas, in the Spring, and the severe rust showed up in a week! One time it wasn't there, then it was!

It was on a Ford high performance 2.3 turbo AT that came with a factory aux cooler after the radiator tank, and I had added another cooler in series.

After mentioning this, I found a couple other hot rodders that had experienced the same thing. So we all went thermostats.
