I pulled the non lockup converter out and put a stock one in. I didnt change anything over for switching to lockup because I wasnt sure what they had done to the tranny to run non lockup, but it looked like they only did it electronically., but lockup actually happens in certain conditions. Only when its been on the road for awhile, and it will lockup tighter and tighter depending on the amount of throttle, and in any gear but 1st. Its really annoying. Plus it wont downshift once this is happening. It will also lockup when Im going up a steep hill. So either this is lockup happening, or my clutches are doing something funny when the tranny gets hot and the line pressure gets high..or something. I wonder what would cause this to happen only when its hot. I noticed the more notches I have the TV cable adjusted out, the worse it is. But too few, and it never locks and slips and shifts sloppy. The whole electronic circuit checks out perfect.
Your issue more than likely is being caused by a sticky TCC lockup solenoid. Replace it with the 7004-r unit. I dont know what has to be done to make it work in the 200, but plenty of people here could answer that. Try adjusting your TV cable a little. Push it in 1 click (so you have less notches showing). On the drivers side of the throttle body, on the TV cable bracket, you push hard on that brass D shaped button and push that related cable towards the front of the car. That D shaped button is what locks the cable in place and keeps it from moving. Be careful cause its easy for it to go farther than you want. But if it does, no biggie. Just adjust it back.
