TH400 making a "laser beam" sound when shifting from first into second. Second to third is fine. All downshifts are fine. Fluid is fine, although there is an undiagnosed slow leak. I really don't know squat about transmissions, but I haven't been able to find any info on the net about this specific symptom. Any help would be appreciated. Thanks.

As for the leaks...check the pan gasket, the place where the speedometer cable connects and that freakin tailshaft seal...that damn thing.
