Transmission Service March 22, 2010, 04:11:31 pm Yahoo Message Number: 111197It has been awhile since I had a transmission serviced on any vehicle. But the last time I did I used someone other than a dealer who used some device to extract the fluid without dropping the pan. They claimed that it actually removes more of the fluid than just a pan drop. I have called a Ford dealer or two and they apparently don't do that and put the rig on a lift. I have to admit I don't cherish the idea of them putting this on a lift. Does anyone know if the method I described is a better way to change fluid or not? If so, are there any shops in the Scottsdale, AZ area that you would recommend?Jim C

The "machine" changes out all of the fluid as it starts at one end and pumps clean fluid in until all of the old fluid is out. Down side is that unless you also drop the pan, you can't change the filter or clean the screen. Or, for that matter inspect for parts/sludge in the bottom of the pan. A pan drop only changes about 4 quarts, but you do get to change the filter and inspect. I do both one time and just a fluid change the next time.
Re: Transmission Service Reply #2 – March 22, 2010, 07:41:11 pm Yahoo Message Number: 111199When I changed our 2003 LD's transmission fluid, I flushed the transmission, after replacing the new looking filter. The pan holds about 7 quarts. The old oil was removed by disconnecting the transmission's oil cooler return line and using it to dump the oil into a bucket. The oil is pumped out while the engine is idling. 4 quarts were dumped at a time and then the engine was shut off while 4 quarts of fresh fluid were added. The engine was restarted and the process repeated until the oil being dumped turned clear and bright red, indicating the old oil had been removed and replaced with new fluid. It took 22 quarts of transmission fluid to fully flush the transmission. The commercial flush machines work in various ways. Some back-flush with solvents, other filter the oil and return it to the transmission. Find one that just replaces the old fluid with new. I use the Factory recommended change intervals and replace all of the fluid each time, instead of just draining the pan. Like Dan, I change the filter every other time.Larry
Re: Transmission Service Reply #3 РMarch 22, 2010, 07:49:25 pm Yahoo Message Number: 111200You might want to check with Ford on this. A month or more ago, on TV news, they had one of those expos̩ things on fluid flushing services and claims. Seems that the auto manufacturers are specifically recommending against them, claiming they can do damage by dislodging any debris that may have settled in the pan etc. This is especially true with higher mileage vehicles. In any case, they say there is nothing to be gained and a lot to lose.bumper
Re: Transmission Service Reply #4 – March 23, 2010, 11:51:34 am Yahoo Message Number: 111216As usual I didn't include all the information in my original post. Our rig is an 06 model with 22,000 miles. The 3 year 36K warranty will expire at the end of this month and I was thinking that it might be a good idea to have it checked for gears sitting in the filter So obviously, the power flush makes no sense, at least this time. I called a few Ford dealers in the area and got my first lesson in learning that many can't spell RV. Called the Ford 800# and they referred me to Camelback Ford in Phoenix. Camelback wanted to do the power flush. Found Sanderson Ford in Glendale, AZ which has a heavy duty truck/RV service department and actually spoke with someone who seems to know what they were talking about. They mentioned that there are two filters on this years model. So will likely go to them.Thanks for the responses.Jim

Here is a link to a web posting showing the whole process done on a Ford pickup, which has the same transmission. Only difference is the E450s use about 22 quarts, instead of 20. http://www.ford-trucks.com/forums/1222821-4r100-automatic-transmission-flush-pics-and-video.html A see though bucket is essential, an automatic transmission funnel is useful. http://www.summitracing.com/parts/aaf-all40108?seid=srese1&gclid=CLWGtoe3z70CFZSPfgodLUQADA While flushing, make sure to put the gear selector in each gear momentarily, once or twice, to flush the valve body. Do block the wheels and set the parking brake.Larry
