It is true the Lower air deflector and valence deflect air to the trans cooler correct? So in saying that, without it, the cooler in the position its in gets absoulutly no airflow, wich could cause the trans to overheat and reduce the life span of it? Correct? Soo why is it such a hard concept for people to understand on the other forum? Seems pretty straight forward to me.

Also on the TSP garage, it states you need to trim the edges of the valence, why?

The Stock Trans Cooler is nowhere near the front Valence or air damn...

it gets "cold air" cause its built in to the air intake system in the passenger fender.

Jeff M once told me that lack of a Valence or front air damn could have an effect on the radiator and the engine cooling, although it will not have any effect on the trans cooler.

Really? From how i looked at it when i fixed my cooler lines, the Air ducting does right by it, not through it or anything, it would seem how my old broken deflector was shaped air would be deflected over to it

Sort of......but the actual air intake is behind the oil cooler which is visable from under the fender/left bumper.

so the air does pass through the cooler that way.

If you were so worried, just cut the stock cooler lines off where the trans cooler is, and put an aftermarket one in front of the AC Condensor?

No slagin the other forums please, were everyones friends here  :wink:

I know I'm bringing up an old topic, but if I was to put a K&N on the turbo, eliminating the whole plastic air intake/ductwork, would the stock tranny cooler still get air, since the tranny cooler gets its air from the engine's suction?

Oh god don't start this again...... :leaving:

thats actually a good question.. I took the 90* elbow that was under the fuse block, and used it underneath to help direct air to and/or over the trans cooler.

If your really worried about it, its stock location sucks no matter how you look at it, get a bigger one and mount it directly in the airflow.

Ok to clarify something... the stock air box hose that disappears into the headlight bucket area IS NOT connected to the duct work below for the tranny cooler! :icon_exclaim: When I first started on these cars that is what I thought also...but if you look the lines do not connect.

The valance works as a positive pressure devise to help direct air to the least resistance instead of just allowing the flow of air to go under the car. Some of that being the trans cooler duct...the rest up and across the radiator. Some swear the vertical valance plastic piece...NOT THE CHIN SPOILER (people get those confused also)...is a needed item and will not allow proper cooling of the transmission cooler if it is missing. Honestly if you add any performance to the motor you need an aftermarket trans cooler. I have an 18,000lbs B&M trans cooler on the front of the TSTE. It is severe overkill but then again my TSTE is pretty frikin strong! ;) If people would just move the stock cooler to in front of the A/C condenser it would allow for MUCH better trans cooling than the stock location. It is in a space saving spot and it SUCKS (not in a good way!) for efficientcy. Move to to where the fans help in normal driving to cool the tranny and they will last MUCH longer! ;)

EXACTLY, Thanks For Clearing this up.  I've heard a lot of confusion on this.  And Aftermarket Trans coolers aren't that expensive.

Yeah, I just couldn't figure out a way to work in the one member who claimed that adding a valance to his lightbulb kept it from overheating...

its easy but not that simple, and if you plumb and mount it in the right way it will work excellent on an auto tranny. all you will need most likely is a small one in addition to the aux unit. the radiators internal unit should be third in line to regulate the temp.

a 5 or 6 speed would not require all the extra plumbing. and Kenny I am confused are you suggesting the chin spoiler has no role in the scooping of air up and over the rad????

Ok thanks it all makes sense now!  :icon_lol:  Now to buy a tranny cooler!

What is not simple about transmission cooling? So you think there should be the stock tranny cooler, another frontal cooler, and the radiator trans cooler?

I gaurantee that if the vertical valance strip was not in place you would have MUCH less airflow up to the radiator than if the chin spoiler was not there. Just a chin spoiler and no valance = next to no positive pressure on the frontal area of the car. Look at how the chin spoiler is shaped and study some basic automotive aerodynamics literature and you will know exactly what I am talking about.

I guess I am missing what you are talking about with the 5 or 6 speed plumbing??
