390BH-60 Fifth gear issue
When I am taking off from a stop or accelerating from 30mph, I have an issue when the coach shifts from 4th to 5th. Once it shifts to fifth, the turbo boost drops to 5-8lbs and the Berk stops accelerating. No matter how much as I press the pedal, it barely maintains speed in the 55mph range on flat ground. Once I go downhill and get to 60mph it shifts to 6th gear and the boost kicks back in. I can manually put it in 4th and get to 60 and then put it back in auto and it does better.
Does anyone have this issue? Have you noticed anything similar?
