Just bought 2001 2500 QC 4x4 SB Automatic 2 weeks ago. Already had my low pressure return fuel line break at the plastic quick connect. Now, when I take off from a stop, feels like I'm taking off in second gear. Soft on the throttle and it's like I'm in granny gear, start rolling and shifts back down,better acceleration. After that it shifts fine, between 50 and 60, it takes a while to shift into overdrive and sometimes shifts hard. When I come to a stop, bumps forward right as i come to a stop. Then while sitting with my foot on the brake, it sometimes bumps again. Anyone that has maybe had this problem would be helpful. Thanks.
