Q45 Transmission capacity

[timatt]

I am getting ready to do a transmission flush/screen replacement on my '91 Q45. Does anyone know the capacity of the transmission? How much Mobil ! should I buy?

Thanx

about 14-15 quarts, although I beleive the capacity is around 11 quarts. you will need the extra to top off after the pan drop.

Or just to complete the flush if you pan drop first.

[Q45tech]

When you do a 3-4 quart pan drop use conventional to fill it back up prior to the flush no need wasting. expensive Mobil 1.

OK I'm a little confused, so could someone outline the protocol for performing a transmission flush? I tried a search, but could find nothing definitive.

Hmm, you couldnt find anyhting, Rex where are you???

This is the way you do it...

Pan drop/clean, filter change, then go do the flush.....
