I have a 2002 Daybreak on a w22 chassis and on my last trip while towing my 8' bike trailer I noticed some slight surging while going up grades. It almost seemed like it wanted to shift down but couldn't. If I gave it more gas I could get it to shift. I left it in the regular overdrive mode since it was all highway driving. Should I be shifting down for hills while towing or just use the normal drive and forget about the overdrive? Any help would be appreciated.

I had surging on hills and it was the fuel filter.

Clutch fan kicking in and out trying to keep the engine cool?

If it shifts in and out of overdrive often the manual says to shift out of overdrive. Surging can be caused by a number of things. Bad ignition wires are one thing to check.

Thanks for the info. I never would have though ignition wires as it seems to be transmission related and only when the throttle is open going up a hill. The engine runs very well but the problem happens under load so it maybe wires?

I was faked out once thinking I had a transmission problem and it turned out to be a spark plug wire that had come off enough to cause a miss under load so I think it is a possibility. There have been a number of reports concerning burned spark plug wires on the 8.1L engine.
