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

with this trans. There is a valve body update to lower the pressure that is
applied to this snap ring. That failure lead to the rest of the damage in

The Basic Parts of an Automatic Transmission (Part 1)
Visit me at: http://www.ericthecarguy.com/
This is part one of my front wheel drive (FWD) automatic transmission
dissection video. In this video I cover the operation of clutches, bands,
accumulators, clutch drums, the oil pump, the valve body, valves, check
balls, seals and 'o' rings, as well as the construction and function of
many of the internal hard parts of an automatic transmission. To be honest
a rear wheel drive transmission isn't much different as many of the basic
components are the same. I guess what I'm saying is that you could use the
information in this video to have a basic understanding of a rear wheel
drive automatic transmission also. It is just a basic overview of the main
components. I don't get into theory and operation so much. Just the
general operation and identification of the parts. I may make more videos
on this topic based on the comments I get so feel free to ask questions and
perhaps I'll answer them in a future video on this topic. There will also
be a separate video on the parts and operation of the torque converter as
well. When that is posted I'll post links below to that video.
