7420L Trans Filler Adapter - Compatible with Ford

1. Fits a 2006-2010 Ford Explorer transmission perfectly 2. This product is sold elsewhere on Amazon for about 3 bucks cheaper so shop around. 3. Many consumers have complained about finding it later on after using it. I'd recommend keeping it in its original packaging and hang it on your pegboard. 4. MOST IMPORTANTLY : Amazon recommends a bottle pump with a hose that screws right into standard quart containers (Plews 55001 Lubrimatic Fluid Quart Pump). It works beautifully but the tip of that hose is a bit too small. You can use a heat gun or hair dryer and heat it up and then wiggle the adapter in there so it's an easier fit when you get underneath the vehicle.

A "must-have" for maintaining your Ford transmission fluid level. It's well made, fits my 5R55S transmission, and the price is right. You need another tool to pump fluid into the trannie using this little "adapter". That's pretty much the end of my review of this product. But, I need to have a little rant at this point... because... the fact that I need this product is frustrating to the max. Somewhere along the line, I didn't get the memo that most everything switched from SAE to metric... and... why on God's green earth was the transmission dipstick eliminated!!!??? That's what started this boulder rolling down the mountain. Why would the average owner want to ever check their transmission fluid? Forward is almost gone and reverse IS totally gone. What's the 1st thing to check? Transmission fluid of course... duh! But, where the #@!! is the transmission dip stick...!!!??? Huh, there isn't one... When a service station opens up - I'll just drive to the nearest one to get it checked out. Except, she (my Explorer) won't move. How much will this process cost? Will my girl get stranded due to lack of cash to cover the worst case scenario of needing a new/rebuilt trannie (over $4k)? How long will it take? Now to check my transmission fluid level (which you can do without this, but, you can't fill it without this - see the attached pic of how to check trans fluid). I have to elevate my Explorer, creep under it, remove a 2-stage drain plug with a specialized driver and if no fluid comes out - it *may* be low. Maybe not... because if nothing comes out, the test is inconclusive. You'll need this adapter to put fluid in until it spills out. Once fluid comes out, then it's full. I spent 3 weeks living under my 2004 Ford Explorer (with 115K miles) - pulling out the transmission by myself after 12+ hour days (working from home of course - I do Amazon AWS cloud architecture/admin) - getting it rebuilt - then putting it back in (mostly) by myself in a hot, humid garage in Austin TX with a normal array of SAE DIY tools (i.e. not metric) - which turns out to be wholly inadequate for swapping out a transmission in a "modern" SUV. In 1981 (or '82), I changed the transmission in my '72 Nova by myself in 1/2 day with a $75 transmission from a salvage yard. It worked great. Doing effectively the same thing for my 2004 Ford Eddie Bauer Explorer (4.0L RWD) - at a cost of over $2,000 and 3 weeks of the most frustrating work I've ever done! But, I saved about $2k doing the work myself. The whole point of my rant here is - if an owner cannot check and maintain their transmission fluid level on their own - the likelihood of proper maintenance goes down, not up. In these busy times, if the owner has to take their vehicle to a dealership to check the transmission fluid level, we can expect there to be more high cost transmission problems, not less. By the way, the best tool I've found to safely look under the vehicle is the jack that functions as a stand also. No rickety ramps or stands that get in the way of the jack when lifting the vehicle. Three weeks living under my Explorer - I wish I had these then…

Worked exactly as needed for 2004 Explorer transmission filling.

works for my Ford 5r55s transmission. (2008 Mercury Mountaineer)

This is a smart little tool. If you have a late model Ford with an unserviceable transmission, you need this tool! I had to replace my radiator and subsequently lost a small amount of trans fluid, since there's no filler tube on the transmission, I needed a way to replace the fluid I lost and this worked like a charm. I highly recommend it for any trans fluid filing needs.

worked perfectly for both my cars

It's the right special tool to fill many Ford and Mercury transmissions that do Not have a dip stick. Actually doing the job takes some time and your expensive transmission is at risk if done wrong.

It worked great

So hard to find anywhere, and for such a garbage transmission.... Fitting works great though!!

This item is very simple really, it has no moving parts, it simply screws in and does what it is supposed to do 'Simple really' but without it the task of filling the auto transmission would be much more difficult, Simple really.

Llego casi 1 semana antes. Falta ver si es la medida que necesito. Gracias.

Exactly what I needed to fill my 5R55S. Does its intended job, what more is there to tell.

Did exactly what I needed it to do. Great product!
