How? I'm not sure how the underpanel has any effect on tranny tunnel temps. I've got the panel and I love it, but I'm at a loss to explain how it would have any effect on what's being discussed in this thread.

had a early version on my 350Z when they first came out, planning to get one for my 370Z.

this^^^ was wondering the same thing. maybe better airflow through the engine compartment allows it to keep it a bit cooler? i just run my a/c with the upper and lower blower rather than having the blower in auto mode, keeps it much cooler that way but then again, it really doesn't bother me.

its just radiant heat from the exhaust and maybe heat from the transmission. ive been wanting to pull the carpet out and sound deaden and add some kinda heat barrier layer in that entire area. when i drive shoe less in the summer i swear i get burns on my foot!

Has anybody come up with other solutions to this issue? Noticed this heat as well. It was driving me nuts because I knew for a fact it wasn't coming from the vents. I may report this to the service department and see what kind of solutions they may have to offer.

It happens to me too. Usually in heavy traffic. I am MT.

I sent an inquiry to a dealership who is handling after market installs for me. I'll post their response if they have any solutions to this (aside from the "just turn the a/c on" fix)
