I was thinking the same thing. I'll have to double check that it got swapped over with the segment, not sure why it wouldn't.

I left my pwm working in my tune. With my triple disk it locks up pretty hard. The pwm helped soften it up.

Also i would set your WoT shift mph and your part throttle (90-100% tps range) alot lower than you want so it shifts based on rpm. Hopefully that makes sense.

It appears that the Force Motor Current table carried over when I did the swap to the 80E segment.

I noticed that there are quite a few differences in the DTC settings for the transmission between the 60E and 80E tunes. Most of the 80E DTC settings are "Non Emissions" while many of the 60E DTC settings are "2 Trips: Emissions Related". Some DTC's are not reported for the 60E and are reported for the 80E, and vice versa.

Should I go ahead and use all of the 80E DTC settings that are related to the transmission?
