Toyota Landcruiser 1991-01

Well this is what The 80 Series
transmission looks like before we start to dismantle the unit. The
whole process from this stage to the final coat of paint will take
four days working flat out while a STD unit can be built in one day.

This photo shows the Landcruiser
transfer case being removed from the transmission before we start.

This photo shows the
transmission completely striped and coming out of the hot wash just
before being taken to the rebuild room for inspection.

This is a 80 series A442F having is
lower case machined dead flat as they are NEVER flat. The machine used
was specially built for us as the surface is so large on many
transmissions, milling such a large surface area will always distort
the case as it builds up heat.

The end result of the machine work shows
that this case has a large bow within it. After machining is finished
the case will be completely flat and free from any distortion it may
have received over the years. There has been many times that we have
found quite large bows within the case, some as large as 40 thou (
1.00 mm ).

Machining and reseizing the front pump
half. These are another item that never seem to be nice and flat.

After cleaning the front pump half and
installing the new pump bush and seal the depth of the gear crescent
is measured and checked against pump gears.

The width of both the inner and
outer pump gears are checked for tolerance after being wet blocked
flat.

The complete pump assembly with new
bushes, end float thrust bearing, drum rings, pump gasket and outer
pump D`ring. End float thrust will no doubt be changed during case
assembly.

This is the new look 6 friction
third clutch pack replacing the standard 5 friction clutch pack with
new radial ground steel plates and heavy duty treated frictions.

Once again we see a new look 6
friction clutch pack, this time the second clutch replacing the old
5 friction unit. Adding extra frictions to any clutch unit will
always increase the load capacity of that clutch.

Part of the process of adding extra
frictions to the 80 series transmission is to get the job done without
having to resort to using thin steels so the machining of the clutch
piston is one way we get the room.

This photo shows a second clutch piston
being modified to help eliminate the 3-2 bind up that we quite often
find within these transmissions.

On the left we have a A442F rear pump
bearing that has lost all of it's hardening and left the skid plate
badly damaged. This is why when we build an Extreme 80 Series
transmission that every Torrinton bearing is replaced. On the right
the new selective skid plate and Torrinton bearing.

This is a close up photo taken though a
magnifying class to check the bearings for case hardening problems, We
will always inspect the old bearings before replacing them to get an
idea on how the whole transmission has been wearing.

This is what the last photo was taken
though. Just thought I would add this photo in just to prove that
we do use a magnifying glass during the building of the
Extreme units.

The main case assembly is finally
complete after disassembling and reassembling for the umpteenth time
to get the end float exactly right. This can take me a couple of
hours by itself using selective skid plates to get the end result just
right.

One of the two new accumulator dowels
that are used as part of the recalibration of the Extreme
transmission. The Extreme Valve Body and accumulator set can be
bolted onto a standard transmission while still in the car giving you
quite a remarkable performance change within themselves. The Extreme
Valve Body kit is available as a separate unit.

We add the accumulator pistons and
springs and where ready for the valve body. Notice the newly machined
case surface.

The valve body goes on and where almost
done but even this has to be done right. An inch pounds tension
wrench is a must.

With the transmission assembly now
complete we enamel coat the transmission before the top coat is added.

The final product has taken a total of
three days to build and another day to paint but the Extreme 80 Series
A442F transmission is now complete. This is when you know you got what
you paid for.

Although only one halve is shown here,
both the convertor impeller and turbine are Kilm bronzed for added
strength. We are often asked to change the stall of the convertor to
accommodate personnel preferences during the building of our convertors.

This is what our custom made Toyota
Landcruiser 80 and 100 Series A442F Kilm bronzed convertor looks like
once it is balanced and painted.
