It was whining a little but I know that it was the imput shaft bearing, the T-5 is famous for starving the front bearing by it's design. I would get it apart and get it fixed before anything more goes wrong, it may last week or months, make sure it has fluid. If you can do it your self you can save a lot of money the kits from D&D and Hanlon are around $150.00, if you need the imput shaft I think they are around $150.0 also, don't forget about a steel bearing retainer
