Add on trans cooler in parallel?
I am adding a B&M 70266 transmission cooler and i am toying with the idea of running it in parallel to the in radiator cooler by teeing the lines. I am thinking it would reduce flow restriction and slow the fluid through each. Any experience or thoughts on this.

Unless you drive it on a roadcourse, I would hook it up in series, trannyto radiator to cooler and return to tranny. Hooked up in this way the 70266 can handle the street or the strip, even with a high stall converter and the transmission will warm up quicker when cold.
If you don't mind the slower warmup, then bypass the radiator for even lower temps. If you plan on taking it on a roadcourse then you would probably need a bigger cooler, especially if you have a high stall converter cheers:

My tranny cooler is hooked up as a stand alone. Temps during normal driving here in South Florida stay at 153* When I drag race the temp climbs to 160* - 164*

It appears from the info above, hooking up the cooler as a "stand alone" would be the way to go. How do the majority of A4 people do this install? I'm curious, as I'm thinking of doing this install...

My cooler is B&M 70266 and is mounted to the lower left (if viewing by standing in front of car) of the radiator. All steel braided lines and russel fittings.
