On a smooth slow go from a stop, it winds up as one would expect thru 1st and 2nd gears. Then when it shifts to 3rd, it darn near immediately shifts to 4th. This results in lugging. Very frustarting when it happens. I bouhg the v6 for good mileage but not for limping around. However when it starts lugging, I can depress the throttle a bit and it downshifts and the revs come up and it accelerates on out as one would expect. The lugging always happens under normal/easy acceleration. If I get on it, it winds thru 3rd and on into 4th as one would expect. I want to try and adjust the parameters to make it stay in 3rd a bit longer so the normal driving does not involve "lugging". I understand their thinking about keeping the rpms down as much as possible. But 1500 rpm in a 3.7 v6 with a large body truck just does not get it. Any guidancw would be greatly appreciated.
