This video is of a CD4E transaxle. This transmission is used in a variety of applications including Ford Escapes, Mercury Mariner ,Mazda Tributes, and a variety of passenger cars. The CD4E transmission is used because it is a compact design that fits many front wheel drive applications. The CD4E transmission has five sets of clutches, two sprags and one band. Many of the problems we see here at Meenan Transmission that occur with the CD4E transmissions are control related. This transmission has a control solenoid pack that contains multiple solenoids that control shift functions, pressure rise, and torque converter lock up functions. This solenoid pack can malfunction and this can cause some drivability concerns. It can also cause a malfunction indicator light to come on or the over drive light to blink. The other more common control related problem is with the pressure regulator section of the valve body. This occurs over time and can lead to a condition where line pressure can go beyond normal and acceptable levels. This over pressure condition can cause internal parts failure. This will likely require removal of the transmission and disassembly for full evaluation. Some of the parts that are prone for failure the forward/direct clutch drum and the overdrive band. When we rebuild CD4E at Meenan Transmissions we take all steps necessary to ensure that a repeat occurrence of these failures can't take place by performing control system modifications that address the route cause of the parts failure. CD4E transmissions after they are rebuilt and modified have proven to be a trouble free reliable transmission and can provide years of trouble free service.

A machine consists of a power source and a power transmission system, which
provides controlled application of the power. 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 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

VW - 01M Transmission - Solenoid 4 (N91) Open Circuit - Valve Body Repair
On this video we see a very common issue with Valve Body problems on these
Volkswagen 01M Transmissions.
Solenoid problems are also very common as you see here. Depending on the
issue or the gear that is not performing properly, will lead you to the
right direction for diagnosis and repair.
This was a rare instance where it only needed to be repaired without
pulling the transmission out of the vehicle. Normally you will see these
unit with 4th clutch damage, burned up. When you see that, the valve body
needs to be repaired and also the molded pistons have to be replaced along
with the normal overhaul kit and bushings.

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.

CD4E Transmission Teardown Inspection - Transmission Repair
On this video we see how to disassemble one of this units. I also explain
the main issues with this unit as I go along with the tear-down. There's an
assembly video coming soon.
You will find this unit on the following vehicles;
Part 4: Removal Planetary Gear Sets, One Way Clutch, Output Shaft, Servo Assemblys
There is a fibro washer there, just take it out. Next is take out the
circlip, you need some circlips that go inside out, these are an
udjustable set that can do both ways. This is a set which i bought from
snap on, part number is PRH32. I have had these for quiet a number of
years so i dont know if they are still available.. but see your local tool
guy and he will be able to let you know. O.k , so i just remove these
circlips... thats our circlip there then we are going to pull our front
planetary gear out. Thats our planet if you want to come over here Frank.
You have our front planet, our anulus and our washer as well. For a
standard rebuild there is nothing wrong with them, they are reusable but we
are going to be replacing them with an upgraded 4 pinion planetary gear
set. The way you check these planets is by moving the gear side by side and
checking the side washers for excess clearance. 10 or so thou is fine. I
am also checking them for axial movement or any rock. We are checking the
pins for wear. Lets put together the planetary, the anulus and the washer
as a set and set them aside. Now.. this is what you call a shell or a bell.
Others call it bell others call it shell. The 3 holes are were our washer
sits. Next one is another planetary gear, this is our rear planet this
works in reverse to give us another ratio. Next in line we have our rear
band drum. Thats the drum the rear band wraps around, check this for wear
marks or heat spots were the band has been running on. This is quiet good
but if you have a lathe give the drum a polish and create a new surface for
the drum to run on.
Next i will pull the output shaft out. We still have our remaining guts to
go, our rear band and our rear one way clutch ( sprag). Once i remove the
shaft we can check the output shaft bearing for any wear. There is no
washers or any other bearings to check and dont be afraid to loose any
parts from here as there is no more loose components. We have our governor
in tact and our 2 governor rings. Going back into the case now, before we
are able to remove our rear band we need to release our band. We can
achieve this by undoing the band udjustment nut , unwinding the udjustment
and creating enough slack to pry out our rear band. Next we can remove the
one way clutch assembly including all its rollers and ellements. For our
rebuild we will be using a modified bolt in sprag to handle the high horsepower. Finally,
we can flip our transmission on its side and remove our servo assemblys. We
can achieve this by using a G clamp and while compressing the servo piston
retainer we can pry out the retainer circlip. I will remove both the front
and rear servo's and once this is done, we have completely disasembled our
727 torqueflte transmission. It is getting pretty dark here now, we will
knock of work and tomorrow i will show you in our next video how to
rebuild a 727 race torquflite to suit 600 horse power.
