AW55-51SN / RE5F22A Transmission Teardown Inspection - Transmission Repair
This is a transmission of a 2005 Nissan Maxima. On this video you will see
the common problem that are associated with this unit. Although there is
rumors out there that a simple valve body swap or new solenoids or even a
shift kit will cure your problem, here we see the opposite. I know that 50%
of your shifting issues can be solenoid and valve body related, but some
drivers push their cars to the limit causing severe damage as you can see
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. Click this link to subscribe to Motor Age!
Repair cvt VT25-E/VT20-E, Saturn, Opel.
Demonstrated inside the repair of variator VT25-E/VT20-E (continuous
variable transmission: CVT), mounted on car Saturn Vue 2,2l 2002-2005 and
Ion Quad Coupe 2,2l 2003-2004. Also installed on the car Opel Signum

How A CVT Works by TEAM Industries.mov
TEAM has received a lot of requests to explain how a CVT works, here is a
good video showing the basics of CVT. In the future we will be posting more
videos explaining some of our innovations to the basic design. Take a look
and let us know what you think.
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.

CVT Transmission Belt to Pulley Clamping
CVT Belt to Pulley Clamping
Get the book here:
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
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

Saturn transmission failure. Not CVT :)
35K miles on eleven year old Saturn. Harsh reverse and or slips into 2nd
gear can be a Loose nut, easy fix.
If you have a CTV failure, I would change it over to the regular
transmission if you want to keep the car. Just takes some new mounts and a
different computer and some other things.
Torque Converters Explained -EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/
In this video I cover the purpose and operation of the turbine, stator,
impeller, and torque converter clutch. I hope the explanation and
practical give you some insight into how these parts work to not only
transfer power from the engine to the transmission, but also how it drives
the transmission pump and doubles the torque output of the engine when you
take off from a dead stop. I've wanted to make this video for some time.
In fact I've had the fans sitting in the back of the shop for almost a
year. Now that I have the Automatic Transmission Dissection video under my
belt I thought I would add a torque converter dissection into the mix. I
hope you enjoy this video and that it gets you a better understanding of
torque converter operation. Especially since I killed my air compressor
cutting this one in half.

Yes this is indeed 'take 2' of this video. I changed a few things to make
the information more accurate. I am going to be posting the old video for
Premium Members at EricTheCarGuy.com just for fun. Here's a link to more

4L60E Transmission Teardown Inspection - Transmission Repair
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.

We specialize in the diagnosis and repair of these transmission series no
matter in what vehicle are they in.
The driving shaft VT25-E/VT20-E. wmv
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
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
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.
