Luxury Coach Lifestyles - View Single Post - 4-speed lockup?

folivier · 05-23-2010, 11:51 AM

On our way home from Desoto SP in northeast Alabama running the hills between Tuscaloosa & Meridian my engine temps are climbing on the hills. Cools off quickly on the downhill side. I'll go from 178 to 190-195, I'm running 62mph. Is there a way to get the 4-speed Allison to shift out of lockup? I'm too fast too shift into 3rd but feel like I'm lugging going uphill.
I did climb a 13% grade for 3.5 miles at 35mph in 2nd gear near Ft. Payne and only got up to 188 so I think my cooling system is ok.
Any suggestions?
