Fifty150

It looks like the 8F35 uses 8.5 liters of ULV. Most likely, it's 4 liters for the drain and fill. It has drain plug. You can fill through the vent port. It's almost like the 6F35. Service procedure looks the same.

The fluid specification and fill capacity should be in your owners manual.

My environment is not as harsh. There's no snow here. I might get 10 days of rainfall in a year. My average temperature is 55 degrees Fahrenheit. The coldest nights may be 45, with the warmest days around 65. I've had wipers last 3 years, plus. In my climate, I could get away with buying the least expensive wiper blades, and it would not make a difference. The same way that I can use the least expensive tires. From what I recall, the difference between the left wiper and the right wiper, is some sort of wind spoiler design. I guess if you use the right wiper on the left, or left wiper on the right, then the wind will blow on the wiper the wrong way. There are not many options for 29". There are more options for 28". I don't know if anyone will miss the extra inch.

As was the case with my F-150. OEM Ford Motorcraft lasted 9 years. AGM Optima lasted 6 years.

If it's the new version built by VW, then I know nothing. In 5 years, you will be the person giving advice.

Motorcraft wiper blades are not known to be great. Nor are they inexpensive. For each of us, we have to determine if there's value to a $30 item, vs a $9 item. I have bought $5 wiper blades from Amazon. They worked. But maybe in my climate, I don't battle harsh storm conditions. I also want longevity. I don't want to replace deteriorated rubber flapping and a plastic frame scratching the windshield, every year. Nothing worse than spending $5 every year, when $20 blades can last 2 years?

Costco sells an Interstate Battery with a 3 year replacement warranty. That may be the best option for me.

My Transit Connect is 2016. Battery still seems fine. It starts without hesitation. But it's on my mind. Sooner or later, a new battery will be needed. The Motorcraft battery is a size 40 or group 40 battery. A size 96 or group 96 battery will fit. Ford has a group 96 battery, which offers no advantage over the group 40 battery from Ford. It's just an alternative, if for whatever reason, the group 40 battery is not available. Ford even has battery spacers so that you can install the group 96 battery into the Transit Connect battery box. For daily driving, without anything like a refrigerator, aftermarket sound system, a rooftop refrigeration unit..... I don't need anything more than the OEM battery. The OEM battery on my F-150 lasted 9 years. The Optima battery I replaced it with only lasted 6 years. The Transit Connect is 6 years old. I'm hoping that the battery has a few more years left. In my case, the OEM Motorcraft battery from the dealership may be the best option. 3 year replacement warranty. 100 month limited warranty. Less than $150, compared to spending twice that much. And depending on the mood of the service writer, or if there's some sort of coupon online, there may be a discount on pricing or free installation. The other buying option for me, is directly from Interstate. Interstate Battery has a shop right by the airport. They have a good warranty, and provide service. In my case, I will also check with Costco for pricing. Costco may be able to sell an Interstate Battery for less. But I doubt that it will cost less than $150 Ford Motorcraft. The Odyssey AGM battery looks nice. As does the Duracell. My only problem with buying a battery online, is when they charge a core deposit. It's ridiculous to think that I'm spending $50 or more, to send a 50 LB used battery back, to get a $22 deposit.

I like performance exhaust also. On the Transit Connect, that's not available. No aftermarket performance exhaust. You can fabricate. Cut out the resonator, and replace it with a straight pipe. Cut our the muffler. Maybe add a glasspack. You'll make noise. It may not sound good. But it will be loud.

Ford sells 2 separate 29" blades. One is for the driver side. One is for the passenger side. Ford also offers a 28" wiper blade which will fit both driver and passenger side. You can use 28" or 29". You won't notice the difference. A lot of the wiper blade companies do not have a 29" blade. Sears sells a 29" wiper blade.

It would be strange if all that fluid that was suppose to be in the transmission torque converter somehow wound up in the sump. More likely scenario is that someone else poured in 4 quarts. I could imagine that a tech who didn't know what he was doing, added 4 quarts. Then the shop manager decided not to do anything or say anything about it. Because it would cost them more money to drain out 8 quarts, and refill with another 4 quarts. Probably one of the two shops in December 2021.

You do not need to do that. There is a tool. It's called an o2 sensor wrench.

I can't wait until I get my recall notice. Then I can get the van fixed for free. I almost paid out of pocket.

It may or may not help. I would do the complete transmission service. A triple drain and fill. That would accomplish 2 things. 1, you would know that you now have clean fluid, not partially diluted dirty fluid. 2, with every drain, you will know that 4 quarts of fluid is coming out, and that you are replacing it with 4 quarts. And it will also let you know that there's something else going on, if you just added 4 quarts of fluid, drove it around, and then 8 quarts of fluid comes out when you drain it again. Makes you wonder if some tech at one of those shops decided to pour in 4 quarts, maybe accidentally, and not say anything about it. Then the service writer at the shop just decided to tell you that the fluid was fine, because they were too lazy to drain it out and fill it again. it may, or may not, make a difference. But the fill specification is 4 liters. Not quarts. That's actually 4.227 quarts. So that's 4 quart bottles, or 1 gallon container, plus 7.560658 ounces. As I recall, I bought 3 gallons of fluid, plus 1 quart. On the first 2 drain and fills, I only filled with 1 gallon. I figured it wouldn't matter, since I was only using it to dilute dirty fluid, not driving 100,000 miles with less fluid than specified. Then on the third fill, I used a measuring cup to add the correct amount - or as close to the correct amount as I could possibly get within an ounce or two.

Mercon LV is a specification. The conventional wisdom is to use a fluid which meets specification. In the case of a dealership, they will use what the manufacturer recommends. A Ford dealer will use Motorcraft Mercon LV. The next option is using a licensed product. The wording is where it gets tricky. Some brands actually say that it's a licensed product. Other brands simply say "approved for use"., or "recommended for". And then there are ATF formulations which are suppose to be "multi vehicle". Multi-vehicle formulations are typically used by lube shops, where they have to service all sorts of different vehicles. These formulations are not specific to your transmission, or anyone's transmission. That doesn't make it better, or worse. Some people report that their vehicles run fine with a multi-vehicle ATF. Look around. Do your own reading. Then decide for yourself what you want to do. GBL has reported good results with Triax. My own history of various ATFs include using boutique brands, and "house brands". I cannot with any certainty say that any brand has outperformed another brand. Royal Purple, Redline, Lucas, Wal*Mart SuperTech, Motorcraft, O'Reilly's........and more. All of these fluids have gone in and out of my transmissions. With automatic transmissions, just like engines, regular fluid changes will yield better results than trying to see how long you can keep using the same fluid. You really would not want to use motor oil for 15,000 or 20,000 miles. You really would not want to use ATF for 100,000 or 200,000 miles. What I can say, relevant to Ford Transit Connect 6F35, is that my van currently is using Valvoline MaxLife without a problem. Just check out what's available. Read the data sheets. Read the reviews. Notice how Valvoline is licensed by GM, and recommended for use with Ford, but not licensed by Ford. And Phillips 66 lists the licenses and license numbers. Whereas Peak says, "recommended for use" with the license numbers, but doesn't actually say that it is licensed. Maybe it means something. Maybe not.

This is the unit I bought a few years ago. https://www.amazon.com/gp/product/B07MQ8GHG3/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

Post a few photos of your issue. Sometimes it helps to see it. You narrated description has left our imaginations to run wild.

Sometimes, that's all that it takes.

ForScan recommends several. It's right on the website, with links.
