Torque convertor rumbling when 1000-1500 rpm and 40-45mph.
2007 Toyota Tundra 6 speed transmission torque converter rumble strip and failure.
When stopping for a traffic light/stop sign from 40-50mph, the truck stops normally. After about 1. 5 seconds when at a complete stop, the truck gives a kick. It is severe enough that it feels as if you had been rear ended. The whole truck shutters. I took it in to the dealership who gives the, "I can't duplicate it" spiels. My tranny fluid was low due to a leaking rear seal so they blamed it on that. They changed the aluminum front driveshaft as they stated it caused the leak. Problem never went away. Does not happen at any other time. Suspect the first gear clutch packs are releasing and re-engaging. Could be mechanical but it is also a possible problem with the transmission ecu. Similar issue with the 2007-up camry which was determined to be the torque converter.
