The first thing I did 2/3 of the way home on that homeward bound trip was to replace the Crankcase Filter. I had no record of its previous replacement and it did look a mess. Carefully replaced it and with more attention paid to RPM’s and gear selection, the issues did not repeat on the balance of the trip. Thank you all for your thoughts on this. Dale

We have the ISL425 Cummins in our ‘09 Camelot.

Greetings to everyone! Starting the 1300 mile journey south for the winter season from Washington. We have some fairly steep climbs that I want to understand better about how to climb with the Alison in our 2009 Camelot 42’. Coming home this last June, we encountered a couple ‘Stop Engine’ lights and lost power at uncomfortable spots on the road. This summer I drained the coolant and flushed the system after degreasing and cleaning both sides of the CAC & the radiator. Re-Filled the coolant system with Final Charge (Red) and topped it off after a couple short runs as needed. I also replaced the recovery tank pressure cap. All this in hopes of not repeating the Stop Engine issues. My question is this; I’ve been told by several people I trust with years of diesel driving experience that I’m not driving the transmission aggressively enough if I’m just leaving it in D. Yet I have a very experienced friend on this forum who I’ll call my “Sensei”, tell me that it’s not necessary with the excellent Alison Transmissions we have. Can I help myself avoid these hot engine issues by keeping the RPM’s higher and the torque in a better range when starting up grades? Thank you for your consideration, Dale
