Last week I went to GLD and (long story short) ended up shattering my output shaft. I was hoping to get a replacement shaft installed this week and that I'd be good to go.
Unfortunately, when the shaft broke, it took out a "lube dam"
. To fix that little plastic bearing/washer requires the trans to be removed and taken apart. 
I went online to find out about a "lube dam" and found the following (btw - it was helpful to include the word "transmission" in the search criteria
):
A planetary gear arrangement has one or more planetary gear sets each having a carrier assembly in which a plurality of pinion gears are rotatably mounted on pins supported in a carrier housing. An annular lube dam is attached to the carrier housing and includes a first and second annular sidewall portions extending radially inward and joined by an axial wall portion. The radially innermost sidewall portion directs lubrication fluid to the support pins for delivery to the pinion gears. The axial wall engages notched portions on the pins to ensure the angular orientation of the lube passages formed in the pins. The outermost annular wall portion provides a thrust washer bearing surface between the carrier assembly and an adjacent transmission component to support relative rotation therebetween.
