Hi, I admire lots of the work people have done here with aero mods but I do wonder about some of the parts that are not monitored by temp gagues. Auto transmission fluid in power steering and teansmissions gets very hot and its life is shortened greatly by high temps. A quick web search will give many sites that show a direct relationship between temp and fluid life.

My 98 V6 cmary has a trans oil cooler ans a small power steering fluid cooler (this is just a loop of metal tube with the fluid passing through it. It is about 1.5 feet ling and it sits in front of the radiator).

Grill blocks would reduce the airflow over these parts and as there is no temp gague for them I would never know how hot they are.

A gearbox or power steering failure is a huge cost, probably more than a lifetime of fuel saving from the grill block, even more frequent servicing of these things would probably eat up the money saved in fuel.

I have not heard any mention of this issue, possibly with the gentle driving it is not an issue? Anyone had any problems or thoughts?
