For most of the sub-assemblies, this involved removing a snap ring to gain access to the internal parts, then replacing any clutch plates, seals, or bushings. Perhaps you might consider doing it the first time with an experienced mechanic. Replace any parts as necessary. I then noticed that I had mistaken a large block-off plate that was part of the main shift kit for a component of the gear command kit, an add-on kit that allowed full manual control of the transmission. If the dimension is below 1. Replace seals and wipers as necessary before assembly. The 4L60-E is an automatic shift, four-speed overdrive, longitudinally positioned transmission.
Lubricate the front pump seal and pump bushing with TransGel or transmission fluid, then install the torque converter onto the transmission input shaft. Then connect to the new single-pin connector at the transmission. If the sprag is intact, install it into the torque drum. A strong magnet works well for this. Check for any damages on the case lugs and bolt holes. Remove the pump housing bolts and carefully pry the pump out of the front of the case. Remove the valve body bolts and the lower valve body.
Even if you plan to replace the gasket, it will be easier to remove the gasket in one piece than to clean off all remnants of the gasket from the valve body or separator plate. The first area is the pump rotor and pump slide to top of pump pocket clearance. Sudden grinding noise with no prior warning primarily in 2nd gear, behavior in reverse may be abnormal: sunshell is fractured. There is no spring force behind the support, so the lock ring should disengage easily. You may freely link to this site, and use it for non-commercial use subject to our.
Remove the transmission mounting bell housing. The plate can either be replaced or repaired. The third area is the stator support bushing; this leads to the turbine shaft journal clearance. Finally, once you are done with this, you will have to assemble the unit. That can completely lock the transmission depending upon which valves are involved. When car has been turned off for a bit, then back on it will run normally.
The steels for the overrunning clutch should be 0. The 4L60E transmission weighs 146 pounds dry, and 162 wet. So, it is highly important that you follow the manual and work step-wise. Remove the lock ring for the forward direct clutch, then the backing plate. The reverse drum needs to be checked and cleaned. We welcome your comments and suggestions. Spilling fluid everywhere, I got the transmission ready to run.
Click for larger image Disassemble the input drive shell forward clutch, reverse clutch, sprag, direct clutch and inspect all parts. There are two splines to be engaged, and one drive lug the double slots on the main converter hub to engage with the pump. There will be at least one additional check ball to capture when the plate is removed. I tackled the rebuild process one sub-assembly at a time. Note that a leaking front seal usually means the bushing is walking out. Inspect the forward sprag clutch.
Lightly lubricate and install the input planetary gear set assembly. The socket has four locking tabs which need to be compressed inward to allow the socket to be pushed into the transmission. Try not to run or drive the car or further damage could result. Transmission must be removed and rebuilt. Given enough wear, the balls can go through the plate and render the check system ineffective.
If you suspect valve body damage, you can remove solenoids and valve spools to inspect them and their bores. It is designed to handle much more engine torque and vehicle weight than the 4L60e, but is also physically heavier than the 60. Install the tailshaft housing and seal the end with a suitable cap. The brake pedal arm makes contact with the switch when it is all the way out. These elements usually include — roller clutches, gear assemblies, sprags and shafts.
