no shifting problems on my 06 for almost 5k now... ... i have shifted it manually as well as let the auto do the work..... I love that it has a TOW MODE plus the O/D LOCKOUT both.
I truthfully have not had any of the issues I read about previous years with my truck such as bad shifting, poor ABS, poor mileage, terrible heater controls in cab, noisy cab, torn weather stripping, leaks, hopping of axle, etc.
I also got on dirt road yesterday and punched it and left two nice tire digs for about 50 yds before my speed caught up to the tire rotation... . in 4wd hi.
I LUV MY TRUCK>. >>>LOL Will love her better after the Nitto Terra Grapplers go on in three days..... I add the Bushwhacker fender flares and decide what I am doing next. LOL
