Although full synthectic is my preference, coventional petrolium based oils would work as well, and have for years. So im re reading the post and am still a little confused but i think im getting it. Are you sure you don't mean Mercon V? Without this valve you can accomplish the same result by loosening the rear most fluid line from the transmission passenger side, near the transmission support cross-member and putting a hose over the line leading into the drain bucket. I think I had around. Because the Heavy Duty F350 Ford pickup truck is used primarily as a work truck, it is often subject to conditions that it was not originally designed to handle.
Thanks for reading and giving some input. I did some research on some of the more popular forums that discuss the 4R70W , , and found some people mentioning that they were able to use the cooler lines to perform a fluid exchange. Alternatively, you can unscrew the transmission fill bolt and fill it thru the transmission … fill hole, but the bolt is very tight and every time you take it off, you need to install a new pressure washer, plus it's very messy. Position the bucket so that you can easily see the quart markings point the markings toward the driver side if you are working solo. If you tow regularly, I would reduce that interval to every 20,000 miles.
Repeat until you have added 13 quarts with the 4R70W. Or, you can drain the pan and fill with Mercon and run the engine in neutral for 10-15 minutes. Note that Ford does not recommend ever changing the filter. As long as the fluid meets or exceeds Mercon V, you will be fine. Although full synthectic is my preference, coventional petrolium based oils would work as well, and have for years. If i wanted to have someone else do it, it would be done already and i wouldnt be a member here. I have never removed the fluid from the cooler but I would drop the pain and change the filter, if your pan has a bump in the bottom you will have deep pan that takes the big filter that is a real filter not just a screen.
This is a lifetime lubricant and only needs to be replaced if the unit has water invasion. Started engine, watched fluid pump out into bucket until you begin to see first sign of air bubbles, turn off engine. If your Excursion hesitates when shifting gears or seems sluggish shifting from one gear to the next 1st to 2nd gear, 2nd to 3rd gear, 3rd to 4th gear, etc. I am a synthetic fan in my cars - using Mobile 1. Don't forget to run the shifter through the gears at least once, pausing for a few seconds in each gear. Filling is the fun part.
There are myriad web pages on the internet for servicing the 4R70W, as it is the automatic transmission commonly used in Mustangs and in Crown Victorias, but very few resources when it comes to servicing the transmission in a truck. When empty replace plug and remove upper fill plug. I dont haul but i still want the best for my money. Most tranny fluids on the market today meet both Mercon and Dexron specs anyway, and thus they can be mixed. You will be rewarded with a transmission that lasts.
Then fill the dip with as much as it just sucked out? Take it easy and slowly work the truck back and forward. Refill through the dipstick tube with the same amount as you just pumped out. And also Mobile 1 synthetic. It makes no sense at all to me to change the fluid and leave the old filter inside the tranny. Regardless of what the factory recommends for a mileage interval, I recommend changing the fluid and filter every 25,000 miles.
The dirty fluid in the converter will mix with the clean fluid in the pan. Your 350 dipstick should be in the same position as the 150. On some gears, you may experience a slight delay in movement while fluid fills the valve body. Put your drain pan under it. Nothing worse than brand new fluid leaking out due to over or under tightened bolts. I was personally frustrated with the lack of any useful information on performing the fluid change procedure, so I researched and researched and put together this guide. Is this the same for my manual transfercase? This will allow you to have enough to route the other half of the tube into the marked quart bucket.
Check for leaks and fluid level before you take it for a ride. Run the engine for 30 seconds, then stop and add six more quarts. Its about 3 feet long. Unfortunately when I cracked open the manual for our Ford Torqshift transmission, it became apparent that the owner-maintenance was excluded in the design considerations. After all, that's what it came from the factory with in the transmission, power steering system and the transfer case. The truck may have warmed up at this point, so you can break until it cools as the exhaust will have gotten fairly hot from the constant start ups. Written by a Ford Transmission engineer himself.
Am i going about this the right way? Pop The rear diff is lubed for life - unless you ever notice a leak. Remove the plug from the transmission pan and drain fluid. Half the people at prestone will tell you it is ok to use the long life coolant for all engines, but that is incorrect. I noticed a drain plug on the bottom of the pan with a rubber washer around it, can I drain it through this drain plug? Make sure it is dry before reinstalling. Put the top plug back in and you're done! Im glad im getting good advice from fte once again. Any other recommendations, and why? I will be doing that after i replace the anti freeze!! You can always use the rest later for other automotive maintenance procedures. To get the new fluid into the transmission it needs to go down the rather small transmission dipstick tube.
Any advice will be appreciated. Measured 5 quarts exactly, so refilled with 5 quarts. By this time, the engine and transmission should be warmed up, so check the transmission fluid dip stick to see if you are in the hash marks. Being your located in So Cal, and more than likely will travel across that desert just to the east at some point, I would go with a 5-30w full synthetic oil, doesn't have to be motorcraft, any quality brand will do, I just avoid store band oil. I wouldn't waste money on the Chilton book.
