I took my bus to a mechanic today (first checkup!). I told him that when going up hills I can only reach about 40 mph max. Straight, level roads I can easily get up to 60.
It has an E350 with a C9 (?) transmission. He said it's a 3 speed, and it is shifting into 3rd going up hill and that it was 'geared low' and normal.
Is it really normal?
