i noticed today, for the first time in 8 months since i got the truck, that on the highway at a steady 61mph, sometimes the TC would lock up and throw the rpm's up about 300rpms. i did it 3 times today, in no pattern like climbing hills or anything, it just did it. she stayed locked for about 30-40 seconds each time. i've never had it happen to me before, should i just deal with it or is something wrong. the OD light doesnt blink.
