any suggestions on a specific brand tranny cooler and shift kit?

Here's a MTX conversion for sale, if you're still undecided.

look at the following link for the shift kit and transmission coolers

you can also buy a B&M transmission cooler from summitracing.com. Long Tru (whats on IPTs site) and B&M seem identical to me. Both should work great, just which ever one you prefer.

So no one ever really answered my question about the TCU compatability. Any insight on that?

First of all, there are no different ones. If you want to use your TCU with a TT ECU, then you will have to give up "pulling timing" during a shift.

ok, your N/A ECU allows feedback from your TCU which tells the ECU that when the transmission is about to shift gears, that it pulls ignition timing. This creates smoother shifts, and "supposedly" makes less wear and tear on the tranny due to less stress. The wear and tear part is debatable. I believe that if it does, its not much. No one has broken a tranny yet due to it.

In a TT ECU, there is no input for feedback since all TT's were manual, therefore the timing does not drop for shifts, so your shifts aren't as smooth. Personally, I like the harders shifts because it shifts much quicker.

mk, so that would be part of the reason for me needing to beef up the tranny? But other than that I should be set right?

No, you beef up the tranny because you'll be making more power. The tranny cooler is to obviously keep the tranny fluid cool, because heat is the #1 killer for auto trans. The shift kit is to lessen slippage between gears, aka make your shifts quicker and firmer.

You could use your N/A ECU if you wanted to, you would just need something to compensate for the larger fuel injectors, such as Apexi AFC or Greddy Emanage. However the TT ECU has been dyno proven to give extra hp.

Do all of mankind a favor and do the conversion. An auto tranny in this car will make you look and feel like a poseur. props to girl with fast car and the knowledge and dedication to make it fast. Leg humping complete. Mission accomplished.

ROFL! Thanks I guess

I prolly will end up going that route. Since I re-enlisted i wont need my car to get around, so It'll be ok to just sit for awhile until that gets done since I wont be driving it.

I already have an APEXI SAFC and a TT ECU but I guess If I just do the ATX -> MTX conversion all of this is irrellevent. Good to have an understanding of it all though anyways. Thanks again.

The other option is to tint the windows so dark no one can see in, never ever let anyone see inside, and roll backward occasionally at lights. Ricing can be very economical. Don't take what I said about being a poseur too seriously. The fastest WRX in the world has an auto tranny.
