P1860 code, help please.

[Ger-Fire-Form-93]

Hi guys,
my wife's 97' TA has some trany problems.
last nigth on the track and a WOT , when was time for the 3 rd get in, the "service engine soon comes on" and RPM's begins to fall.
I reset the pcm and the light comes off, but I raced it again and the problem returns.
the scanner gives me code : p1860 TCC PWM Solenoid Circuit - Electrical.
default action:*DTC P1860 will be stored in PCM history
*Inhibit TCC engagement
*Inhibit 4th gear if in hot mode
*Freeze 1-2 shift adapts from being updated

If I set the shifter on 3 rd gear, it works fine, but in automatic mode it dont work as should be.
what can I do?
any experience whit this kind of problems?

sorry for my bad english.

Type in the manufacturer and the trouble code. You'll find that the code refers to:

Occasionally, vehicle manufacturers will use the same DTC across different vehicles and platforms. If the DTC that you entered above returns more than one DTC description below, you will need to match certain digits of your VIN to determine which DTC description applies to your vehicle.

In your instance, it is the torque converter clutch circuit but you'll have to use your vin to get more specifics.
