Even though the Banks unit hooks into the tranny connector with multiple wires, I finally figured out that all the Banks unit does is to intercept the wire from the variable pressure regulator solenoid and run this wire through a "differentiator" circuit so as to give a temporary boost in the line pressure while shifts take place.

Basically when a shift occurs the PCM commands a momentary increase in line pressure, and the Banks unit just amplifies this to give a firmer shift. After the shift occurs the PCM returns the line pressure to its steady state level, and at this point the voltage on the variable pressure regulator solenoid is constant so that the "differentiator" circuit in the Banks unit has NO effect because the derivative of a constant value is zero! The only way to achieve the needed steady state increase in line pressure as a function of fueling, boost, etc..., is to reprogram the PCM!

Very nice. I didn't know that much detail about the Trans Command, but now I do. Thanks for the heads up.

Ive had my trans comand for about 4 years or so it is on my Ex that I use to tow a 30' toy box, i never had a issue with hard shifts, or any trany issues, (knock on wood) It was a pain to install I did't like messing with the pins in the trans wire harness. But I have been very happy with it. You do pay for the Banks name, but im ok with that. the product works and thats what I wanted.

Banks does. He loves it and laughs all the way to the bank with your money. Forget the junk and buy a BTS Valve Body and get a tune which will help and be way better.

I had one installed on my truck and liked it until one day I looked under the truck and the box was hanging down. The case rotted where the bolts attach and the unit fell down and was held by the cable. I tried calling and emailing banks and they never provide any helpall I wanted to know was if I could get a new case for it.
