Just an FYI, pass through seems to have some issues scanning 5 speed Alli controllers. Just got my trans back in, and I was watching the Pressure Control Switches to make sure everything was engaging and reporting right, but in pass through they all acted like they where disconnected. Fortunately, before I dropped the pan to check that I pligged it back in, I noticed that the TFT was at like 68*, which it wouldn't have been if the PSM was unplugged. Checked with BBL, and they where responding right. Jsut FYI; Let me know if I can provide any more useful info.
