I hate to see you give the old girl up. I think you and I are the only two Metro buses that are out there running. I got poked at constantly at the Branson rally last October for running with the DOT bumpers.

I am still using the ECU you gave me for the Voith Tranny. I have 2 other spares, but neither will release the retarder action without shifting to neutral and back into gear, otherwise they work fine. I use the Voith retarder extensively when driving through the mountains. That tranny has worked flawlessly for me for 21 years.
Hope you sell fast. Good luck.
