ms3x with microsquirt transmission controller

Alright so ive got my 98 gt up and running with the ms3x. Its currently got a t45 in it and I want a 4r70w. I ordered a microsquirt kit on friday and will be using it as a transmission controller. I have a few questions though, does this just talk to the ms3x over the 2 CANbus wires? Does the microsquirt require a firmware download like the megasquirt? If so, where do I find the firmware for the 4r70w and how does it get loaded?

If you ordered the MicroSquirt as a Trans Controller from DIY Autotune, it will come with the Trans firmware already loaded. If you have a regular MicroSquirt coming, then you will need to load the firmware. One trans firmware for all supported transmissions.

You can download the trans firmware from:
Megasquirt Downloads Firmware and Software - Megasquirt EFI

I did order it from DIY Autotune but I did not specify that it was for transmission control. I ordered the microsquirt with the universal harness as they dont have one for the 4r70w yet. So I will load the firmware from the page you linked, is the procedure pretty much the same for loading the microsquirt as it is for loading the megasquirt?

Yes, same deal.
If it comes with B&G firmware on it you will need to bootstrap it, on a microsquirt there is a bootstrap wire in the harness.

The TunerStudio firmware loader supports and has been tested with the trans firmware.
