<VV> Differential pinion adjuster O-ring

[Mike McCrae]

The manual tranny and diff are supposed to share fluid  and maintain a 
common level.
Make sure your gasket between them matches that hole in the center bottom.

Subject:  Differential pinion adjuster O-ring

Does anyone know what happens if the o-ring is missing from the differential 
pinion adjuster? This is a 4-speed manual transaxle.
I just finished reassembling the transaxle and installing it on the engine 
when I discovered that I did not install the new O-ring. As far as I know, 
there is no o-ring on it at all.
It looks like a small amount of oil may seep through the threads until the 
oil levels in the transmission and differential matched. I am estimating 1/4 
inch between the bottom of the transfer hole (between the transmission and 
differential), and the bottom of the pinion adjuster threaded hole. So the 
transmission may drop 1/8 inch and the differential rise 1/8 inch after a 
long sit. Then during operation it should pump back to the transmission 
until proper levels are restored when it starts running through the transfer 
hole.
Even though it seems fairly inconsequential, I will probably try just 
draining both units, pulling the transmission back off, removing and 
reinstalling the pinion adjuster ring (with the o-ring this time) and 
reassembling.
