Im sure mine doesnt have one because it doesnt have a towing package. I just looked at some pics of them on google. Didnt know if this was a money wasted item or not. Being that you live in a hot climate, I would recommend a cooler even if you dont tow. If you are not familiar with the way this transmission is designed in the F150, refer to the diagram below. I removed the heat sheild but there is no room to turn a wrench.
You knew that you didn't have one and that it was a good idea to have one from reading about others adding it. Immediately, look below the truck at the bucket and wait for the transmission fluid to begin flowing. If you don't have the additional trans cooler, I'd strongly suggest adding one. This part is where having a partner is helpful because someone can watch the fluid filling the bucket. 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. This will allow the new fluid to cycle through the system. Note that Mercon V is not a brand, but a lubricant characteristic specification created by Ford Motor Company.
Anyways, how do you know if you need a trans cooler? Is a hose plugged or restricted? I have a F150 4. Keep the brake pressed when you are in a different gear and only stay in gear for about 5 seconds. The pan itself has some weight, but will be considerably lighter since it does not contain an entire 4. You have now emptied the bulk of the transmission fluid in the pan. The factory heat exchanger cooler that comes in the radiator doesnt really cut it. Hex fitting on the radiator. Route the tubing around so it does not kink anywhere.
Oh well, i will know next time. I dont pull anything over my towing capacity and usually nothing close to my trucks towing capacity. Is the voltage 10 volts or greater? Heat kills automatic transmissions, actually it kills automatic transmission fluid, which in turn kills the transmission. You need to take it out either way. Dont know if my transmission even gets hot to begin with.
I believe that anyone with a general knowledge of automotive handywork should be able to do this job on a weekend afternoon. When you begin removing the last few bolts, the pan may want to start dropping, so keep it supported. Position the bucket so that you can easily see the quart markings point the markings toward the driver side if you are working solo. On some gears, you may experience a slight delay in movement while fluid fills the valve body. I would say if you are asking about it then you already know that you should have one. 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. The Bottom line on the radiator is the In Line Hot from the transmission.
Add some fluid if needed, but only a little at a time. No, i think you got it backwards. Not good, but no harm done. I read alot of posts about guys adding transmission coolers to their trucks. 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. I would try not to extract more than 3 quarts at a time. Always expect the first time to take longer.
Is the resistance less than 5 ohms? Match the size of this bucket or containers with the number of new quarts of Mercon V that you plan on using. I know they can help the life of an automatic transmission, but is that the only reason? Is the voltage reading greater than 10 volts? If this were in the truck you would be looking at it from inside the drivers seat direction. My point was that you knew enough to be asking about it. Didnt know if this was a money wasted item or not. Under normal circumstances, approximately 4. As Bucko said, look at your radiator, there will be some lines on there that are more than likely for your trans cooler that is in the radiator. The holes in the gasket will line up with the pan only one way.
Does the vacuum control motor hold a vacuum? Im asking because i saw in a post that someone had added one to their truck. Since my truck is a 2002, I was not able to access a drain plug in the torque converter. I am not sure which transmission you have, so I will list the lines for the 4R70 and the 4R100. Even tried a pivoting flare wrench but no go. Is the connector correctly attached to the blower motor switch? There are lots of aftermarket parts out there to buy for an F150. I have a F150 4. Before we proceeed, I should explain what exactly is being done in this procedure since I am not simply regurgitating the information in the Haynes manual.
