Yes, it shifts up and down, but tends to stay in 3rd or 4th gear at very low speeds... It's far from refined in my opinion, dont know whether it's normal. It does not jerk, and such, but rather changes at very low rpm. If i floor it does kick down, but stays in that gear until 3000rpm and does not change to the next if i dont ease off a bit. Dont know whether it' normal. Is it dangerous to drive with pump activating at 1 change? What does it indicate? If there is a leak, is it difficult to diagnose and repair, or just check hoses and accumulator? Tnx guys, advice greatly appreciated...
