Reprogram kit for automatic transmission?

Hey all,
I am about to rebuild the A340H in my truck and am wondering if anyone has experience with one of those reprogram/ shift kits or even if they make them for Toyotas? I checked B&M but it looks like they do mostly domestic vehicles.

 

The B&M unit is a quality piece(s) and changed the character of my transmission completely.
( in a good way)

I used one of their shift kits a looonnnggg time ago on the first vehicle I owned, a '69 Camaro SS350. Worked great. Chirped the tires when hittin 2nd gear. I've no experience with them on Toyotas.

 

Where did you pick up your B&M shift kit? I couldn’t find any products on Holleys website or anywhere else for that matter. Also have you noticed any changes in gas mileage with your B&M unit?
