Transmissions: Pros and Cons of Rebuilding Continuously Variable Transmissions
Supported by Transtar and TransTec and produced by Motor Age in partnership with ATSG, this training program explores the various CVT configurations, their operation, parts and tool availability to help you determine which repairs can and cannot be made in your shop. Best of all, this program will provide basic tips for the average transmission specialist to determine if the shop can rebuild that CVT profitably or if the transmission will need to be replaced.

CVT Transmission Belt to Pulley Clamping
CVT Belt to Pulley Clamping Get the book here: https://www.createspace.com/4283730 https://www.createspace.com/371853 The key to understanding how a CVT works, is by reviewing how the chain and cone pulley react with each other. All CVTs have one weak spot, the contact point. This is where there is a tendency for the whole transmission to slip, grind and sustain damage. Incredibly enough, this is not where CVTs fail the most, but more on that later. The CVT belt is composed of two groups of metal rings, each of 7 to 12 rings, and a few hundred special metal links. It is these links the ones with direct contact with the cone pulleys, or variators as they're called by the manufacturer. For good clamping force, the CVT needs a specific transmission fluid. To neglect this fact is to ask for trouble, as the CVT will get damaged due to slipping and grinding between the belt links and the cones. There's also another aspect of the CVT clamping force that needs to be reviewed, which is the hydraulic pressure exerted on the cone pulleys or variator. The CVT oil or hydraulic pump can generate as much as 1000 PSI of pressure. but not everything in the CVT needs this much pressure. Because 800 or more PSI is more than most circuits need, line pressure is regulated down to three lower levels, 220 PSI maximum for the clutches and variator, 140 PSI for the TCC, or torque converter, and 80 PSI for the lube and cooler circuits. The CVT also has a few ... Get the whole story right here in this video...

GM 4L80-E Transmission Rebuild - Transmission repair
GM 4L80-E Transmission Rebuild - Transmission Repair Here is a full rebuild video of a GM 4L80-E Transmission. We see the parts that took for a successful repair. Complete overhaul kit with clutches and steels and molded pistons. All bushings as well. There's some items that I personally would've add to the parts list but since this is for a Transmission Shop down the road this is what I was provided with. Items I would add are: Actuator Feed limit Valve, Transgo. TCC Regulator Valve Kit from Sonnax. 1-2 & 3-4 Shift Valve Springs from Sonnax. TCC PWM Solenoid. EPC Solenoid. And Shift Solenoids if needed.





How to adjust bands and change automatic transmission fluid
This is a demonstration of how I tightened the bands of my automatic transmission and changed the transmission fluid and filter. The vehicle is a 1998 Dodge Ram 1500 4X4 with a 46RE transmission. This repair was done after a transfer case repair which required removal of the propeller shafts. With the front shaft out of the way, access to the front band adjustment screw was better than normal. It is possible to do this with the shaft in place, but access for demonstration is not as good. For details of how the propeller shaft is removed, see my other videos on repairing a Dodge transfer case oil leak. Note that the details of how this is done, especially the torque settings and the number of rotations backward after ideal torque, are very specific to the 46RE transmission. Be sure the locknut is backed off enough that it doesn't bottom out when the adjustment screw is tightened. Before ever doing this type of procedure yourself, you should consult the dealers repair manual and verify the specific procedure in your car. This is an amateur demonstration done for entertainment purposes only. The information offered here is given in good faith but with no guarantees of accuracy or safety. Any misadventure you encounter if you decide to do maintenance on your own vehicle is your responsibility.

Driven shaft VT25-E/VT20-E.wmv
http://www.avtoakpp-cvt.com Slave movable cone (pulley) with bearings (only have nine balls) is based on the output shaft of the variator (CVT). Drive shaft consists of movable and fixed cone. Progress is also movable cone is 22 mm. Push force necessary to create friction between the metal belt and pulley cone shaped push-plates and a spring in the control cavities moving cone. Unfortunately movable cone seals can not be replaced, as outer "cup" seamed, so it is detachable. Of course, if you have too much you can try the shaft on a lathe to cut the outer "cup" through the rolling and open. Then after replacing the seals brew.

Merriam-Webster defines transmission as: an assembly of parts including the speed-changing gears and the propeller shaft by which the power is transmitted from an engine to a live axle. Often transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device... Manual Manual transmission come in two basic types: - a simple but rugged sliding-mesh or unsynchronized / non-synchronous system, where straight-cut spur gear sets are spinning freely, and must be synchronized by the operator matching engine revs to road speed, to avoid noisy and damaging "gear clash", - and the now common constant-mesh gearboxes which can include non-synchronised, or synchronized / synchromesh systems, where typically diagonal cut helical (or sometimes either straight-cut, or double-helical) gear sets are constantly "meshed" together, and a dog clutch is used for changing gears. On synchromesh boxes, friction cones or "synchro-rings" are used in addition to the dog clutch to closely match the rotational speeds of the two sides of the (declutched) transmission before making a full mechanical engagement...
