Transmission Fluid Change Question
We are new owners to a 2002 Itasca Suncruiser 32V. We picked it up last year with 35k mileage and have nearly 40k on it now. Being a Licensed A & P Mechanic, I am no stranger to caring for any vehicle I have. I have done just about everything I needed to do on this unit to maintain her road readiness as seen by the nearly trouble free 5k we have put on it in the past year.
Here is my question: Even though there is considerably low mileage, there is nearly 18 years since sold new. So, I have no transmission troubles I just wanna be proactive. I noticed there is a drain plug on the transmission pan, A Mechanics dream ! At any rate I want to take advantage and replace the transmission fluid or as much of it as I can without dropping the pan. I have researched and found out the system holds 17.7 quarts of Dexron Mercon ATF. So, I would like to drain it and then refill it. Taking into account the fact that the torque converter holds fluid, approximately how much? And also taking that into account how much fluid should I consider purchasing for the fluid replacement?
Thank you in advnce for your assistance in answering my question.
