Completed swap and was working through DTC's... first time I really drove it on the highway any distance it set P0894. I double checked all my wiring thinking surely I had something wrong, but everything looked fine.

Before the swap, I had the transmission rebuilt at a local shop.

I made these screen shots to take to the shop to tell him it didn't look like it was locking up.

He dropped the pan and said there was metal in the pan(not sure what other diagnosis he did). Said the trans needed to come out. When I got it back and he said he rebuilt it again and replaced all the electrical components and that it had burned 2 sets of clutches... 3rd and not sure the other....

Anyway...I uploaded the current tune and a log file from a short drive.
