Len - Next time you hear the "trans roar", check your engine temp using the CCU display. The idiot dash gauge has a designed dead spot in it somewhere between 90 and 100C where it stops reporting until coolant temps exceed the 100C mark. The digital readout on the CCU always reports correctly. At low speeds the Aux fan will come on around 95C and once moving agian the fan clutch will begin to lock up. The fan clutch does sound kind of like a 747 taking off; hopefully that is what you werre hearing.
