Would you happen to have another ICM with coils still attached handy as a test?

I just checked ou the coils after the car has been running for 1/2 hour.

coil 1 (6,3) - 5,983 ohms
coil 2 (2,5) - 5,995 ohms
coil 3 (4,1) - 5,910 ohms

So the bottom is off by tad compared to the other 2. not sure if this is a big enough difference though

will that actron CP9110 or whatever scan this car with the right adapter cable and give me the information I need?

The scantool will give you data on the TCC slip RPM'*, as well as the TCC Apply percentage... and what gear is called for...

And being the hybrid OBD and a half junk, you also have the Missfire data as well...

weather or not that will aid you in finding the real problem may be another story...

If my friend had a 3800 Module I'd send it to you... Not enought 3800'* blow up for me to strip modules off of... We have seen 1 LN3, 1 L27, and 2 L36'* blow up... Been a while tho...

Hard to say what may be wrong without being there to experience the problem..
