Are you totally set on limiting your issue to the tranny?
Hows boost? look normal? have you checked you up pipes, intercooler hoses etc?
My experience has been:
low boost, poor fuel mileage, and loss of power= either boost leak or exhaust up-pipe leaks.
If it's more of a loss of power ordeal, the tranny is the last place I'd look.
How about fuel filter? Clean fuel bowl? Smell any fuel up under engine which would signify possible bowl drain orings.
How's the engine valley on top? Dry?
just my $.02 worth.
