[T3] Back to my auto trans diff oil change.

[William J]

I know and Ray is so far the only one who ever brought this issue up. I've 
been driving this car since 86 and as far as I know the seal has never been 
changed . As far as I know the diff could have been over filled the 6 oz 
well before I got this car.

 The gear oil I drained out was not thin it was far from trans fluid. The 
failed diff's so far have been way over filled and the owners were losing 
trans fluid with no leaks outside.

 But thanks for the warning. All I can do is keep an eye on it.

I would be concerned that the seal between the diff and tranny has failed, 
diluting your oil.  I’ve read about a failure something like this on the 
Samba, and it can be repaired but do not delay as tranny failure can follow 
if you wait.

Change the seal, gaskets and o-rings between the differential and automatic 
section...every 7 years or 70,000 miles.....or else suffer the fate you have 
most probably suffered.

It is very common that the seal...which is not perfect material for either 
gear oil or AT fluid...but is a compromise......eventually fails. When this 
happens, AT fluid gets into the final drive SAE 90 oil. It can cause 
failure. This is very common. I wiped out two transmissions this way before 
I learned.
