Today, I dropped my truck off at my local trusted repair shop to have my trans flushed. Well, they said they couldn't do it. They couldn't find a fitting to take apart to hook the machine in. They said they talked with the dealer and they said, you may need to replace something if you do this. (I stopped listening when they started telling me this crap).

So, I have a 2007 F150 5.4 4x4 with the tow package. Where does someone break into the line (without cutting the dam thing) and hook the flushing machine in?

My Ford service manual shows 4 connections between at the radiator and at the aux cooler. Plus 4 on a connector block in the lines between the trans and the radiator. And 2 at the trans itself.

I don't understand why they can't figure this out.

Anyone know and better yet, have pics of where you would hook in?

Thanks

 

I believe some places will access the fluid line at the trans cooler which is in front of your radiator. You need to find another shop. There are several places on your rig where they could easily tie into the fluid lines to flush your trans.

 

+1 what he said. I hook in to the top cooler line in the radiator just below the air intake tube. It takes a special tool to take the line out.

 

What is the special tool? Maybe they just don't have that or who knows.

Unfortunately, I have very few shops to choose from and even less that I trust. I'm sure if I can give these guys the right info they'll be fine.

Thanks

 

Why do you want to flush it? are you having problems or just routine maintenance? just curious.

 

No problems, yet. Hoping to postpone the inevitable. Especially since I plow with the truck and it has 95K of rather hard miles on the clock. It's time, heck, it's overdue in some peoples eyes.

 

I recently flushed my '04. I purchased my own equipment to do the chore. I found that the none of the fittings that come with the machine fit this truck. I disconnected at the tranny cooler both sides. According to the flow the driver's side is the pressure side from the tranny and the passenger side is the return. I put the machine in series with 5/8" hose and hose clamps on the tranny lines. Attached quick disconnects to the exchanger. Then I started the fluid exchange. 10 to 15 minutes latter I was done and cleaning the tools.
Word to the wise. Till the fluid gets to temperature the thermal block (#8 in Bridge's diagram) near the tranny that both lines pass through does not engage. Simply put, after you disconnect both lines when cold and put both lines in a bucket to see which is the pressure side they will both push fluid out. When hot and thermal block is engaged (theoretically) only the driver's side will have pressure. I would say about 30 to 40 lbs. I did not measure it.
Next time on a cold tranny I will probably intercept on the tranny side of the block but then that does leave old fluid in the radiator and cooler that you need to purge manually.

 

need help, i have a 2007 5.4 lariat, and the water reservoir is taking in oil, not sure if its atf or engine oil but looks like a redish milkshake. what are the causes of this and how can i repair it. i want to do the job myself but need some info please help!!

 

You simply need to replace radiator and then flush transmission . You can get get a good radiator online fairly cheap . Just make sure the lines terminate exactly like the one you have . Make your own drawing . I would not drive it until you do .
Some radiators do not even have a trans cooling loop . You can change pans on trans for a drain type ,which is what I do then change out mercon V 4-5 quarts at a time over a few days . Only use MC mercon v . I usually run thru about 20 quarts to clean it out . You can buy all this on amazon .

 

svt, maybe you should stop using the term 'flush', as this is generally regarded as a bad thing on a trans. I think what you're after is a 'total fluid exchange' which is done as the others stated. The engine is started and the trans internal pump pushes the used fluid into a cylinder with a floating piston, with new fluid on the other side, which is thereby pushed into the fluid return line from the oil cooler. This continues until all the fluid is changed.
Otherwise, you can simply pull the trans pan yourself, replace the filter and replace the amount of fluid you drained with new - this is simply called a 'drain & fill'. This gets about half the fluid but if you do it two more times, like 5000 miles between, you will pretty much get it all. Then you would do it at about 15,000 to 30,000 mile intervals or yearly to keep it fresh. Its also feasible after the first D&F/filter change to simply use a vacuum device to pull the old fluid out of the pan by way of the trans dip stick tube and also replace it by the tube.
