Transmission Repair - AW55-51SN / RE5F22A Transmission Teardown Inspection
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

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

Transmission Repair - 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.
Transmission Repair - Allison Transmission LCT 1000 TransGo Kit Installation.
Trans-go shift kit instrallation.
Here we see step by step on how to install a Transgo Shift kit and the most
common failures that you see in this unit. This unit is built to last and
is very powerful. With this kit installed it makes it more hevy duty than
it already is.

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

Driven shaft VT25-E/VT20-E.wmv
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
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.
Transmission Repair - 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.

Kathys Saturn Vue transmission repair
Saturn Vue CVT transmission removed from vehicle, and disassembled to show
the customer the damage inside the transmission. The worn shaft is only
available as part of the very expensive belt and drum assembly. That part
plus the rest of the damage in the transmission make this transmission too
expensive to rebuild. This vehicle needs a complete transmission
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.
Transmission Repair - Transmission Solenoid Testing (Ohms Law)
Transmission Solenoid Testing. Here I use Ohms Law for testing. I believe
that this is the only way to test your solenoids on or off the vehicle.
Remember that the solenoids fail under LOAD! So just Ohm testing on its own
is not really accurate. Other tests can be done, but if you just own a
VoltOhmeter, that should be all you would need to perform your testing.
Voltage drop testing is also accurate but you also need to put your
component under load.
Ohms Law, Learn it, make it your own.
Voltage Divided by Ohms equals Amps...
The D-Drive Infinitely Variable Geared Transmission
This brain-bending invention could be the holy grail of transmission
technology - it allows you to smoothly move through gear ratios from top gear all
the way through neutral and into reverse without ever disengaging the
engine. Plus, there's no friction drive component, so the power is always
transmitted through gear teeth - there's never any slip or friction losses.
In fact, the D-Drive's main difficulty is that it's so damn hard to
understand that people don't really know what to do with it. So here's a
close-up look, which will hopefully get a few people thinking.

Transmission Repair - GM 4L60-E Transmission Re-Assembly (Rebuild)
On this video we go through the re assembly of a 4L60E Transmission. I
tried to make this video shorter for you so I skipped the bushing
installation and installing the bolts on the valve body. But you can go to
the teardown video for reference on where each bolt goes, since they're
different sizes. I will make a follow up video on bushing installation.
