i have a rebuilt 95 4l60e behind an lt1 that is making a whining/whirring noise.i just got the tranny in yesterday.it isnt loud enough to hear outside in idle but driving it ,its very noticable.it has a s10 v6 converter that i believe is one of the higher stall factory units. it seems to be driving fine just the noise worrys me. could this be a problem in the pump? maybe the converter?
