Help with a GM piece of ****

[Bigstang1]

Hey guys i feel bad even bringing this up in a ford forum, but i know u guys and feel like i belong so instead of starting new in a gm forum i figured id ask here first. My 88 cadillac brougm (ride while the stang is getting the T5 swap) started makeing this really loud whinning sound when in gear idleing but not in neutral or park. Im pretty sure it is a bearing in the torque converter. If u let the car idle down the street as soon as it reaces the speed where the car is going as fast as the engine is idleing the noise oges away. Anyway does anyone know what this could be? if it is the converter are they hard to swap out? Do you just pull the tranny back and pull out the converter and put in a new one? Im trying to make sure that that is the problem b4 i spend more money one somthhing other than the stang. Sorry for the long post and for asking a GM question

it's hard to say without really hearing it.sounds like one of three things. low fluid level, clogged filter or the pump is going out. that whirring sound is the pump hunting for fluid. thats what my 74 t a did before the pump went out.gradually will get worse and makes that whiny whirring sound all the time. course it could be something else but i'm not a gm tranny pro.
