Sensors built into both the motor and transmission send data to the computer, and the computer uses this data to determine when it is the best time to shift gears. This is a junk transmission. Install the backing plate and lock ring, and check the clutch clearance as previously described. Under the wrong conditions, the plastic coating can melt, allowing the bare wire to make contact with a segment of wire further down the coil. This transmission can still be found in light-duty van applications as well as in the overseas market in the Holden Commodore. Remove the lock ring for the reverse input clutch, then the backing plate, clutch plates and steels.
But you can go to the teardown video for reference on where each bolt goes, since they're different sizes. I'm still driving, but will echo the broken record of symptoms, 2 days ago engine starts revving at high rpm's, won't shift to the next gear, have to let up on the gas to get it to eventually shift. Luckily they are easy to diagnose, easy to replace and fairly inexpensive. Took it back to the same dealer. Assemble the low-reverse support plate and clutch stack on a flat surface and check the overall thickness of the stack at its extreme outer edge.
Use the ohm meter test as described above, and if you get a reading below 20 ohms you can assume that there is an internal short in the solenoid. If it has not already been done, drain the torque converter completely. The magnetic field in turn moves a plunger that is connected to one of the valves in the valve body. It was 100 out that day. Press or drive a new pump bushing into the housing with a suitable tool. Guess what, I was over the mileage for the coverage! Although this transmission is certainly not in production as widespread as it once was, there are still some applications that utilize this transmission.
Notice weird down shifting feeling, told my mechanic, he said he's not noticing anything weird. In preparation for installation into the vehicle, it would also be good to clean the cross member, lines, and vehicle wiring harness. They are garbage and the maufacturers do not care and will not help at all! Pass the transmission main electrical connector through the hole in the case and fold the wiring harness out of the way. Fixing transmissions is a bit like plumbing — you have to recognize your limits. In 1993 the 4L60 was updated to add electonic controls and it was designated 4L60E. This is not an area to be overlooked.
Can anyone explain the process of how to do that? I am attempting a 99 into a 97. The 3 pieces are the bellhousing, the main case, and the tailhousing, all 3 are made from cast aluminum alloy. It was also available in luxury cars like thed and the Escalade. In either case, you need some point of reference- something that will show you how to proceed when you are not sure or have no idea whatsoever , and that is exactly what this book is designed to do. What a piece of junk this 4l60e is. Turning the input shaft counterclockwise will be more difficult, and should result in an opposite rotation of the output shaft.
Does the truck have any trouble codes? The shop who did the work stated they touched nothing but the trans. Install the reverse input drum by aligning the clutch plates and rotating the drum as necessary to engage all the plates on the inner hub, as well as the outer fingers into the reaction sun shell. The transmission weighs 146 pounds dry and 162 pounds with the fluids installed. Install the clutches into the case. Remove the 3-4 clutch steels and plates, apply plate, and retainer, being careful to maintain their order as removed. I'm new to tranny's but because of these sights, my first total rebuild is almost done!! Scuffed or damaged spools must be replaced.
The 3 Most Common Problems With The 4L60E Transmission Posted by on Monday, April 29th, 2013 The 4L60E is probably the single most popular automatic transmission currently in use by American consumers. Most instances these providers have sometimes unfinished or inappropriate diagrams that will perhaps cost the shop lost cash moment if not possibly a lawsuit. Also the speed sensors must be in good working order. Inspect the steels and clutch plates as described above, and replace any parts as necessary. Core Information: Buyer is required to swap a good core for this transmission otherwise there will be a core charge in addition to the above price.
We live here in Alaska 250 miles from town. Test the reverse sprag clutch operation. Mornings or when it sits are the worse, you actually have to put the car in Neutral and the vibration stops that's how bad it is, sounds like it's going to fall apart. I do not know if it has ever had work on it in the past. Once the current is disconnected, the magnetic field disappears and a spring is used to return the plunger back to its original position.
Lightly lubricate the pump rotor and vane support rings, and pack the pump cavity with TransGel or Vaseline to insure fluid pickup once the transmission starts to operate. You didn't mention that both were 2wd or 4wd. That can completely lock the transmission depending upon which valves are involved. Once removed, clean up both the plunger and plunger bore with a fine grade of emery cloth. I opted for the Trailblazer. After about 30 miles it settles down some, but I can still notice it. Snap the wiring harness conduit to the valve body bolts.
Gas to the floor and 25 mph. If no reading is returned, you can assume the wire is broken. Aside from rebuilding the valve body, the solenoids should be tested, along with the temperature sensor and pressure sensors. If the steels are intact, they can be cleaned and lightly honed, stoned flat, or ground to break any surface glazing. Just wondering if I will run into any issues. There are two splines to be engaged, and one drive lug the double slots on the main converter hub to engage with the pump. Something that will never happen again.
