Don't be surprised if there is rust and junk in them. Ã¨ P … lastic petcocks easily bind. Having a bed on the back to haul around your belongings was only a bonus. . It offers faster engagement, quicker shifting, smoother operation, and increased service life.
Step 1 - disconnect the battery, negative first. Coupled with the electronic throttle strategy, the transmission computes the output torque required to maintain the vehicle speed, and chooses the correct gear and converter state accordingly. I've done enough of these that I can replace the plugs in approximately 45 minutes but don't be surprised if the first time you do it takes a few hours. The Ford F150, equipped with the 4R70W transmission. Before opening a plastic radiator petcock, spray it with some penetrating lubricant. Frequent fluid changes, especially when used for towing, are the single best method to prevent shudder.
Use a combination of extensions, swivels universal joints , sockets and ratchets to get at them. If there is a real need to change the transmission fluid, one simply unscrews the drain plug on the bottom of the transmission. Until Step 6 is complete. The plugs are to be tightened to 13 lb-ft. The Ford F150 came with the 4R70W transmission. Similar to most automatic overdrive transmissions of that time, this transmission incorporates a case of aluminum construction, a fully electronic valve body and a lockup torque converter.
Customers could order from a number of different cab designs, including an extended cab that could hold up to six people. Many of these trucks are purchased solely as work vehicles, and many make their living on these trucks, relying on them to perform day-in and day-out. Step 7 - Using the 10mm sockets, loosen the four bolts of the fan pulley. Make sure you jack it up on completely level ground. Loosen the bolts that hold the transmission cross member to the transmission and vehicle. The project was shelved with a design that lacked a dampener in the torque converter but after the project was revisited a dampener ultimately made its way into the final design.
Newer transmissions that are referred to as 4R70E or 4R75E have modifications that compliment Fords switching to throttle by wire. Next remove the brace from the power steering reservoir to thermostat housing. Once on the ground, slide the transmission out and away from the bottom of your truck. Next remove the air intake tube from the throttle body to the air filter housing. This transmission uses a first gear ratio of 2. Excessive heat is the number one killer of all automatic transmissions, regardless of the make or model. A list of tools needed includes the following:.
Finally back out the 4 bolts to remove the pulley. You need to use some common-sense here since the engine is aluminum, but a crisp shot from the left then the right then the left will eventually free the water-pump. The transmission was introduced when Ford started to downsize its full size line in 1979. Not getting the transmission fluid changed: Over time, the transmission fluid will become contaminated from normal wear and exposure to outside elements. Remove the drive shaft by loosening the straps that hold it to the rear end. If the vehicle is 4x4 the transmission pan is alittle larger and will take close to 18 quarts.
You can also get it in two-door regular cab, and four-door Crew and Supercrew models. While there is some speculation that the 70 can be multiplied by 10 to indicate the ft-lb of torque this transmission is capable of handling including torque converter multiplication, i. It makes it possible that the friction material can slip or the transmission could overheat. I take an old piece of seat foam and put it on top of the radiator support to the engine to allow me to lay on it without hurting my tummy. Drain the cooling system completely. Exceeding the maximum allowable payload: This can be compared to the issues you encounter from towing over the maximum limit. Once this occurs, the fluid will lose its ability to properly lubricate the internal parts of the transmission, resulting in accelerated wear and eventual failure.
This helps both low speed acceleration and durability. Trucks that are used for work are also often over-worked and abused. Step 10 - Look how pretty! The plugs are way down in the hole which is why I use the extension then the swivel. This transmission unit includes a transmission case, valve body, tail shaft and housing, torque converter automatic only , and all internal lubricated parts. The new water-pump installed and bolted tight.
