This part is where having a partner is helpful because someone can watch the fluid filling the bucket. 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. Dont know if my transmission even gets hot to begin with. Follow up procedures should go a lot quicker. Sorry about the incomplete previous post, hit the wrong key. I am not sure which transmission you have, so I will list the lines for the 4R70 and the 4R100. This will allow the new fluid to cycle through the system.
This saves some time at the end of the procedure. If you don't have the additional trans cooler, I'd strongly suggest adding one. Keep the brake pressed when you are in a different gear and only stay in gear for about 5 seconds. They all look similar to me. I'm replacing both lines right back to the rad and cooler.
Connect the 101 mm 4 inch test heater water hoses with plug and adapter to the core tubes. Get under the truck and leave the vinyl hose connected, but move it out of the way. I have a F150 4. Heat kills automatic transmissions, actually it kills automatic transmission fluid, which in turn kills the transmission. I know they can help the life of an automatic transmission, but is that the only reason? You have now emptied the bulk of the transmission fluid in the pan. Since my truck is a 2002, I was not able to access a drain plug in the torque converter. I see that it comes with a the cooler coil and some hoses.
I believe these are supposed to be used for mixing paint, but they work just fine. This will keep the vinyl hose pointing into the bucket. On my vehicle, almost exactly 4 quarts was extracted before I started to notice air bubbles in the vinyl line. You should be familiar with the terms used in this writeup and understand what is meant when direction is specified on a vehicle forward, rear, driver-side, passenger-side, etc. Some are legit in their usefullness, some are not.
Didnt know if this was a money wasted item or not. You knew that you didn't have one and that it was a good idea to have one from reading about others adding it. Even tried a pivoting flare wrench but no go. In my opinion, every fullsize truck should come with a cooler whether it has a tow package or not. Fullsized trucks are heavy in themselves so a truck transmission generates a bit more heat than most passenger car transmissions. Hex fitting on the radiator. I believe that anyone with a general knowledge of automotive handywork should be able to do this job on a weekend afternoon.
I was ignorant when i bought my F150 and bought one without a towing package, assuming that all 150's towed the same. For additional information, refer to Section 412-02. Route the tubing around so it does not kink anywhere. You can always use the rest later for other automotive maintenance procedures. Is the voltage reading greater than 10 volts? Some are legit in their usefullness, some are not.
The cooled transmission fluid then returns to the transmission where it is utilized in the valve body and torque converter to keep the vehicle moving forward. Im sure mine doesnt have one because it doesnt have a towing package. If this were in the truck you would be looking at it from inside the drivers seat direction. The truck may have warmed up at this point, so you can break until it cools as the exhaust will have gotten fairly hot from the constant start ups. Drain all of the coolant from the heater core. Dont know if my transmission even gets hot to begin with. I got the top nut loose prettt easily.
Didnt know if this was a money wasted item or not. Always expect the first time to take longer. The Bottom line on the radiator is the In Line Hot from the transmission. Position the bucket so that you can easily see the quart markings point the markings toward the driver side if you are working solo. The filter may or may not drop along with the pan. I knew you could get a truck with one but didnt know there was an aftermarket trans cooler until i read that someone had added one.
Please excuse the crudeness of my drawing Basically, the transmission utilizes a closed-loop cooling system where the transmission fluid is pumped forward of the vehicle to the radiator where it is cooled via the engine fan and airflow when driving down the road. Out towards the front of the truck, left side. As long as the fluid meets or exceeds Mercon V, you will be fine. Being that you live in a hot climate, I would recommend a cooler even if you dont tow. I think I had around. If you are not familiar with the way this transmission is designed in the F150, refer to the diagram below.
