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

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.

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!

Saturn Transmission Line Pressure Control Solenoid Replaceme
This video chronicles the process of replacing a Line Pressure Control
Solenoid (inside the valve body) on a 1999 Saturn SL1 A/t w/80k Miles.
The symptoms were that the transmission was slamming into gear when
The solenoid was purchased from the dealership.
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.
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.
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 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
