There is actually 10.5 quarts of Oil in the CD4E.
Here is my thoughts...
I service my original and replacment transmission at the 30,00 mile interval.
BOTH transmissions failed within 2,000 miles of the service.
Both transmissions worked flawlessly prior to the service.
You have over 94,000 miles on your tranny.
If you are financially prepared to pay for a transmission replacement,
you can take your chances and flush the tranny,
but put the money for the replacement in the bank and don't spend it.
If you don't need the money for a new tranny, it will earn some interest.
If you need the new tranny, your car will drain your bank.
So don't do the flush unless you can afford the possible consequences.
