Well I just bought my Tacoma, 58K miles an 2011, 4wd, double cab, certified truck, And the Automatic, is like surging at 40MPH, like not locking up Torque converter or, what?, and when you let off the accelerator, it's like your putting on the Brake, feels like it's in a lower gear as it decelerates rapidly, So what does any one make of Theae Symptoms,? Tyranny was probably never serviced even though it was a certified Truck!!
