Honda Transmission Rebuild Video - Transmission Repair
Honda Transmission Rebuild Video - Transmission Repair On this video we see what it takes to Rebuild a Honda Transmission, what parts it takes and what has been working to correct some of the common failures on these transmissions. Blue Overheated Torque Converters has been a common issue on these Transmissions for a long time and we still see this regularly to this day. Although there are various shift correction kits and special valves out there, all work really good on correcting the issue with the lack of converter feed fluid. I like them all. So if a deciding factor is important to you on which method to use, all I can say is this, They all work. Keep in mind that there are "other" fixes or items that can be added to the rebuild, but it is not really necessary if they're not really needed, I'm not mentioning any but I know some of you will. With that being said I like to thank you for watching this video and liking it and sharing it. Thank you guys for your support. Please Subscribe if you not already. Thanks.





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...

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.

The driving shaft VT25-E/VT20-E. wmv
http://www.avtoakpp-cvt.com The driving shaft. Piston forward is one of the weaknesses in the variator (CVT). Major failures because of it. Rubber deposited by curing on a metal part of the piston - hardens and loses elasticity. Height (thick-ness on) a rubber bumper is only 5 mm, and height of the cylinder in the fixed part of the cone leading shaft is also small. During compression clutch forward, the piston is so out of the cylinder, which creates oil leak on the outer circumference of the piston. Reduced contact area between the piston and cylinder. Falling oil pressure ball valve on the piston does not have time to close. Piston periodically presses, the press clutches. And as a result is obtained: 1. Twitching of the time away. 2. Wear of the friction, they simply burn out. Increased clearances and there is a metal ring. 3. Of clutch friction material are particles that fall into the oil block of solenoid and a valve, which causes them to malfunction - jamming valve (plunger). 4. Wear surface of the cones. 5. Wear metallic belt. 6. Crushing balls in the slots. 7. Chips in the slots themselves driving and driven shafts. 8. As a result - jamming mobile cones. 9. And later breakage of the metal belt. 10. In the torque converter divides the overrunning clutch.





Allison Transmission - LCT 1000 - Teardown Inspecton
Teardown Inspection and Preparation For Shift-kit Installation. Here we see an Allison LCT 1000 teardown inspection and you can also see how this transmission is being used on some heavy duty trucks. Very tough and durable. On part 2 of this video, we're installing a Transgo shift kit to make this unit more heavy duty than it already is. So watch part 2 of this video as well.





Honda Transmission Repair 2
On this video we see the necessary parts needed for a successful rebuild on these Honda units. The main issue is the converter lacking lubrication and burning up. There is a new valve from sonnax to correct this issue. As well as the "O"ring end plugs and TC check valve. SUBSCRIBE above, click the like button and leave your comments bellow. Thanks for watching.





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.

On this video we can see the disassembly of a 2006 4L60E transmission. The most common failure on these units is 3rd. clutch burn up, the reaction sun shell and the 2-4 band. Failure on these transmissions is not necessary the way it is treated, rather is these common or pattern failures. Valve body ware is also another issue and can be corrected installing a correction kit of your choice.
