There is a band adjustment. I don't have the procedure for it, but you could find it if you looked.

I heard about that torque multiplier being more badass than a manual truck for towing. Pretty damn sweet if you ask me. Could that torque be matched with a man trans, if I had it in 1st gear aka granny and in 4 wheel low?

Plus, you won't be doubling the torque very often. The torque increase on a dyno won't be a whole lot. You will get the most multiplication when you are moving at a low speed with a lot of throttle. Like for spinning tires, but the stock converters aren't good for that; they are designed to slip less throughout the rpm range. A transbrake shows the true potential of an automatic.

I will look into it.

BTW, this is the transmission I was talking about wanting to get. Around $970 including shipping. Probably looking at about $1100 or so to get the trans, new TC, new fluid...ain't looking quite as good now, but oh well...lol
