Of course the transmission temps is another problem that needs to be addressed, as the shifting gets worse and worse over higher temps.

It seems to me upgrading transmission mounts would have a greater effect than changing engine mounts. Have people found this to be true. If you change the transmission mounts how much does the noise go up? I am so far only having occasional difficulty with 2-3 shifts while tracking.

First step we need to monitor temps and see how long it takes, and how hot it gets, next step address the problem, either with additives like friction reducer (there is a product not yet available for public use that is proven to work) or in a higher level, a transmission cooler.

Not significant the amount of noise transmitted to the cabin.
Is a lot less than cup at shifter and cables.

I actually have more of a problem going from 2 to 3 in one particular turn at Road America. Would just not go into gear (no grinding or anything). Would just have to hesitate a second and then slipped right in. Did not do it every time either. Downshift has not been a problem (yet).

"Pedals: The OE pedal arrangement made it very difficult for me to execute proper down-shifts"
Can you elaborate on what is required to lower the height of the brake pedal ?
I completely agree the height differential w/ the gas pedal is too much for heel-toe.
Many thanks,
Matthew

The problem exists, period.

So, to that end I think the first upgrade path is a LSD upgrade, then if you're still seeing black tranny fluid and short fluid exchange intervals, we look into addressing the problem with some data analysis and an uprated oil cooler...
