Cannot say, and also it will be difficult to argue against them i guess. This sometimes happens to drivers of turbocharged cars, since the sync-ing of rpm-speed-turboboost level-gear can often go wrong in heavy traffic situations? Am NOT suggesting that is the case here, just that it may happen if your habitual sync-ing of the above is too-often 'off' by a bit, suboptimal rather than wrong or bad i mean, you know? Of course there may be some other reason entirely? all the best --- Double Post Merged, Aug 17, 2016 --- I hope you're not shifting up to say third gear, ONLY to have to shift back down, too soon, in the quest for fuel efficiency? The t-jet has, unlike the mjd, a far wider torque spread EVEN in second. One could stay in second in traffic, even as the traffic's speed goes up (or down), for much longer WITHOUT shifting upto third. That workd out more efficient than shifting up and then having to shift down too-soon, again and again. Please disregard these comments if they're inapplicable to your driving style! cheers.
