This is a good way to identify if you have a 4L60e or a 4L80e transmission in your car. Install the anchor pin for the stationary end of the band and retain it in place with masking tape. Tip it, slosh it, agitate it, and do whatever is necessary to get all you can out of the converter housing. However, the same thing applies here, if your car model came with the 4l80e transmission from the factory, get a driveshaft from one of these models if possible. Clean the valve body and insert the lower body check balls in their appropriate locations. Torque specifications differ slightly between big-bock and small-block Chevy engines and transmissions. These numbers can differ a lot and you will get a lot of different answers of how much these can handle.
There are also differences when it comes to the sensors, mainly that the 4L80e do have 2-speed sensors that are different than the sensor on the 4l60e. When installed correctly, the converter should slide all the way back to the point where it contacts the adapter bell. If you suspect valve body damage, you can remove solenoids and valve spools to inspect them and their bores. Although this transmission is certainly not in production as widespread as it once was, there are still some applications that utilize this transmission. Using a razor blade, remove the gasket from the pan and transmission case.
Use of a professional mechanic is suggested if you do not feel comfortable with the instructions. You have a problem if it gets up to be 250F. Scuffed or damaged spools must be replaced. Even if I had pulled the plug, there would have been that much trans fluid staying in the sump. Prett straight forward, reomove pan probly gonna get some oil spilt on yah, just a fact of life, no oil drain! You can see more details here:. There will be a little metal in pan. Rotating the input drum to help align the clutches makes the task possible, and up to seven plates on a stock clutch you should have counted them need to be aligned to allow full engagement.
Oh, my sump does have a drain plug but after reading here, I didn't mess with it. The 4L60E is differentiated into an early version and a late version. Any wear should be addressed. 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. Inspect the low-reverse clutch steels and clutch discs. Torque the pan bolt to 10 ft lbs or snug with normal ratchet. Reassemble the piston, spring and retainer, then the clutch stack in the order it was removed.
Compress the reverse input clutch spring and remove the retaining ring. The rubber ones are the next best thing. The clutch pressure plate is 35 ft. Install the pressure regulator valve into the pump housing. Lift out the forward clutch housing and spring package, and inspect the springs for damage, distortion, or breakage. Also, is there anything special I should know about doing this? Remember that some points can differ depending on the year and the car model of the transmission and the car you are swapping in.
I think I did cover the most important parts when it comes to the difference and the swapping between the 4l60e and the 4l80e transmissions. How far below the crank centerline does the pan of the 4l80e hang? It was used in both two wheel drive and four wheel drive vehicles. Remove the lock ring for the reverse input clutch, then the backing plate, clutch plates and steels. You can see the pictures of the gasket in the specification above. Using a torque wrench and a tightening in a star like pattern, torque the pan bolts to 98 — 108 lb-ft. Any signs of heavy scuffing or burning should indicate replacement.
It should be on the bottom of the pan a 15mm headed plug. Also when some thing is not right. When installed with the support plate and lock ring, the total clearance of the stack should be between 0. Closely inspect the splines in all locations, specifically the reaction sun shell hub and mating reaction sun gear spline, the reaction carrier hub spline, input sun gear, and the 1-2 planetary ring gear carrier hub. Remove the 3-4 clutch steels and plates, apply plate, and retainer, being careful to maintain their order as removed.
Keep your foot on the brake pedal. Shut off the engine and check the level again. Take some fresh transmission fluid, and using your finger, apply a light coat to each side of the new transmission pan gasket. Remove the lock ring for the forward direct clutch, then the backing plate. Install new filter by pushing strait in.
Model year 1999 and later models require 35 ft. The 4L60E naming also indicates a lot about the transmission. Insert the linkage rod to the manual valve spool, then position the lower valve body and install all fasteners in their appropriate positions. I live in Sweden, and I have been working as a mechanic for over ten years and are a specialist and certified in automotive diagnostics. For the most part, this transmission has been phased out by the 8L90E already, but is still in prodution.
