How to identify a non lockup A999 transmission with pics!
OK, as promised for fishy68, here are some pics of the low gear set I have. There was in fact a snap ring holding the sun gear to the shell, same as the regular one. You can clearly see the difference though. Just so everyone knows, these gear sets are from different units manufactured about 10 years apart. The low gear set was from a lockup unit and the other was not. Factory nomenclature for low gears is 'wide ratio planetary gear train'.
In any event Tracy, you were correct that the sun gear spline count on the standard gear set appears to be the same front and back while the low gear set is larger inside the shell.
Here's a pic of the two sun gears stacked on top of each other. The standard gear set is on top and still in the sun shell. The low sun gear is on the bottom, sun shell side on the table.
I'm not sure if the standard set has this spacer that installs between the larger gear and the shell but it doesn't look like it. If there is one, it's nowhere near as thick.
Now that I am looking at it, the low gear set seems to be pretty chewed up. The pinion gears all look pretty worn.
There is also a nice, circular gouge in the planetary carrier thrust face. Who knows how/why this happened. Look where the tip of the pick tool is, that's a pretty good divot.
Hope that was what you were looking for. Kinda glad I won't be using this low gear set.
