Not that I know of. But with a bit of work you should be able to build a control to turn the TC on and off. Just a mater of knowing which wires to deal with.

TC? I'm guessing you mean Torque converter? or do you mean Transmission controller?

Ok, so I found some info on the whole shift solenoid signal bit. I am thinking about making a mini-controller of sorts. I am not sure about what frequency the PWM to the solenoids is, though I may have a work around for it. I thought of making a pass-through controller that under normal operation the car would run on its own pcm programming, then if I were to flip a switch it would switch to my controller. My thought being that the controller could take the reading from the range switches on the trans harness going to(?) or from(?) [I don't have the slightest clue on this bit] and wire this to a gate IC that would trip the proper combination of pwm outputs for the shift solenoids. The pwm signal can be sampled from the solenoid wires and be manipulated into the combination fitting for the shifter location at the tranny. I'm hoping this idea makes sense. Are there any inputs on this and possibly some help designing this circuit? Some of the info is listed here...

subd. interested but dont have time right now to get into it. anybody know if those signals are 12v or 5v to and from the trans?

SGP358 may have a answer on this. Otherwise, tonight when I get home from work I'll look over the manual and see what I can find.

I am also curious about the signals. From what I can gather they are PWM, though what voltage I have no clue. If I can find out what they are I will post them.

Ok, so what i've gathered on my own the volts to each of the shift solenoids is 12v at 23ohms resistance under normal operation. The resistance is (i guess) the whole PWM bit, so, In order for me to assume control of my transmission'* shifts I will have to make a PWM circuit with an output of 12v @ 23ohms to the solenoids. I will be running this off of the power line to the transmission through a tap. If anyone could help me locate a male and female 20 way connector to this tranny it would be awesome as i dont really want to play with the factory connector any more than i have already or have to in general. I still have more research to do before i mess too much with this, but i will start on making my little circuit board... not like there is much involved...

Ok, so I have the volts, ohms, amps... etc for this little project and thats all in the bag, now im curious about how to wire up the shift unit. I was thinking of using contact switches that would be mounted in the shifter inside the car, then realized the limited space and practicality. I am wondering if the range switch (given the 3 wires in the Trans plug that are labeled for it) can be tapped on the tranny plug to go through a circuit so that i can use them as my signals for the solenoids. If anyone can aid in my brainstorming it would be helpful. I just got back to this project as there were some things that came up.

SGP358 or Billboost may have some advice for this project.
