Transmission Part Numbers April 27, 2023, 05:00:54 pm I'm going to change tranny fluid in a few days but I'm confused on part numbers. The book indicates that I have the Ford 5R110 5-speed transmission. Fluid: The dipstick indicates Mercon SP. Is Mercon LV interchangeable. Filter: The book indicates FT-175. Is FT-180 the same part? Pan Gasket: What is the number for the gasket?Drain Plug: Is there a number for a drain plug o-ring or whatever it has? I was hoping I could just buy a kit off of Amazon or O'Reilly's. Thanks.jor

Very little is unique, but I keep finding things I have never worked on and know little about. The airbag light came on a few months ago. After a couple of hours of reading and investigating, I found the wires going to the seat belt tensioner had become snagged in the seat slide mechanism and torn out of the tensioner's plug and in twenty years, I had never paid attention to the tensioner and its plug hiding under the seat's upholstery.Every day is a new day.Larry 1 Likes

It wasn't cheap to repair!Steve KI was surprised too, didn't expect to see a seat belt pre-tensioner but I was pleased to see this safety feature.A replacement plug wasn't quickly available, we were leaving soon for an extended trip. The plug was then pried out and cut down with a Dremel, exposing the two small terminals that the wires had been soldered to. I enlisted Steve's (aq433) help to solder the wires back into position, he is very good at working on very tiny things...I'm not.Once the plug was repaired, it has worked fine since. I still would like to find a replacement.Larry

Re: Transmission Part Numbers Reply #11 – May 02, 2023, 02:03:32 pm After draining and dropping the transmission's oil pan, you will see that the filter is a fine mesh screen, designed to catch the big pieces. To remove the smaller debris, I use an inline filter inserted into one of the transmission's oil cooler oil lines.Magnafine inline filters can be used for both the transmission and the power steering/power brake system.Ford also sells an inline filter for the transmission.Transmission inline filter 3/8"Amazon.com: Magnefine 3/8" Magnetic Inline Transmission/Power Steering...Power brake booster return line filter m 1/2"Amazon.com: Magnefine 1/2" Magnetic Inline Transmission Filter : Automotive As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
Re: Transmission Part Numbers Reply #12 – May 05, 2023, 05:49:41 pm OP here. Finally got around to changing my transmission fluid.QuoteJor, could you take a few pictures and share your experience changing the transmission oil? I’d certainly be appreciative. Took some photos. It's pretty straightforward. Just have to decide whether to just do a drain and fill or a flush and fill. I went for the drain as this rig, until I got it, never towed. I'll flush it next year. Larry has excellent instructions (above) and I found another nifty way to do it on youtube (flush). Anyhow, the photos are on GooglePhotos at this link: tranny drain1. Get the kit at NAPA for $70 delivered. Again, Larry's info (gotta say, this guy is handy to have around!). Got 12 qts of Mercon SP on Amazon. 2. Drain the fluid (and thank Ford for installing that wonderful drain plug).3. Take out the 20 pan bolts. You can use a wiggle to get a straight shot at rear two but not really necessary.4. Pull the filter straight down (arrow) and drop it into the pan.5. Determine if the O-ring is attached to the filter or if it stayed in the hole. If it's still in the hole (arrow), remove it with a picky tool or a little screwdriver.6. Clean up the pan. Be sure and remove the magnetic washer and clean under it. I use the purple Super Clean from Ace.7. Push the new filter up into the hole and reinstall the pan. Torque the pan bolts to 11 ft. lbs (132 in #) and the drain plug to 13 ft # (156 on #).8. Pour in the new oil. I used 8 1/2 qts).I tried something new that I saw on youtube. The guy called it tinging. Put the pan on nice flat concrete, lay a socket on each hole and give it a whack! Why not!jor 3 Likes

Put the pan on nice flat concrete, lay a socket on each hole and give it a whack! Why not!The bolt holes around the perimeter of the transmission pan distort as the bolts are tightened, as the pan gasket compresses unevenly. There is more force on the metal directly under the bolt heads.It is customary to flatten the distorted bolt holes using different methods, using the flat surface and socket works fine. The same method is used on engine oil pans.Nice work. Some will dump and change the fluid several times to get more of the dirty oil out, changing the filter only on the first dump.I prefer to get rid of all the dirty fluid at once and that is why I use the full flush method.Larry
Re: Transmission Part Numbers Reply #14 – May 06, 2023, 03:54:58 pm QuoteSome will dump and change the fluid several times to get more of the dirty oil out, changing the filter only on the first dumpYea, I'll do a flush next time for sure. Reminds me of the big Allison transmissions I used to have. On the older ones everyone changes over to Transynd synthetic. Those babies take seven gallons for a pan only change so it ain't cheap. Anyhow, If you change it, drive it and change it a second time, Allison considers that 100% Transynd. One thing I really like about the LD compared to the big rigs is how inexpensive it is comparatively. Also, I can handle the tires and stuff which I enjoy.jor

I would assume the five-speed transmissions take about the same.When our transmission was rebuilt several years ago by John Wood, it was filled with Valvoline MaxLife ATF Multi-Vehicle Full Synthetic Automatic Transmission Fluid, 30,000-mile fluid changes were recommended.Amazon.com: Valvoline MaxLife ATF Multi-Vehicle Full Synthetic Automatic...Larry As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
