Just in case someone was looking for a transmission controller upgrade.......

I have one. They are a very nice piece of kit and offer a lot of customization features. But they are designed as more of a standalone system. To make everything continue to work in D2 (like gear indicator), it required an additional conversion box. Currently working on a writeup.

They have been out of stock for a while, but I hear they will have more at the end of January.

 

cool! I would like to see that writeup!

I have installed a few Haltech ECU systems, but never a TCU.....(well...because they were all manual cars)...
