    Looking for a little advice here. I'm active on some other boards, but this seems to be the place to go for transmission help, something I have no experience with. For a while now, whenever I give the car some power during a turn, I can hear a vibration. I dropped the pan recently, and found what looked like part of a pin and some non-magnetic shavings.

    After doing some research, I'm guessing that one of the pinion gears stuck to the shaft, causing it to spin, breaking the pin. This seems to be a relatively common issue with these trannies? I've never done any burn outs or anything, but snow/ice are issues around here, and I like to take curves fast, so I guess it just happens.

    Does this sound reasonable, and if so, what all would be damaged? Can I just replace the pinion gears/shaft/retaining pin and call it a day? If so, where could I find them? I'm over 100K on this car, and the tranny does have some other issues, but I'm trying to keep it alive for a while longer before I have to swap it out.

    Thanks for your help.

    Edit: forgot to mention, this is a Regal LS, so it's got the screwy 3.05 final drive.
