T/700
- 4 speed hydraulic transmission ( GM )
Well this is what most
of them look like in the beginning 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 shot above shows
almost everything that is used to build the EXTREME 700 with only the
convertor and heavy duty sprag race missing. As you can appreciate we
tend not to itemise the contents.
From left to right we
have a second hand set of frictions, a brand new set of STD frictions
and on the far right is the treated heavy duty set of frictions that
are only used in the EXTREME transmissions.
This photo shows some of
the machine work that is done during the construction of the EXTREME
transmissions.
Machining and resizing
the front pump half. These are another item that never seem to be nice
and flat.
Here is a shot of the
two pump halves with the new high Volume 13 vane pump assembly with
slide and the heavily modified o'ringed valving units that are used.
Notice the newly machined surfaces on both halves.
Machining the valve body
flat is possibly not one of the most important tasks that we undertake
with the EXTREME transmissions but it is certainly part of the Blue
Printing process that is undertaken.
This photo basically
shows the valve body after it has been completely stripped down and
made ready for the machine work and valve body updates that are added
to bring the unit up to scratch.
The 2 - 4 band servo on
the left is the STD 553 unit and on the right is the imported 093 unit
that we use, it has almost double the clamping force of the STD unit.

The final assembly of the newly modifies
servo unit with new servo piston and internal modifications done
This is a T/700 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.

We stopped machining this case half way
though to show why it is so important to machine the bottom of the
case. You can see the centre section that is yet to be cleared, about
another 5 thou should do it
This shot shows a T/700
case having it`s forward mounting surface ( Bell Housing ) machined
square to the alignment of the transmission tunnel. The lathe that we
bought to do this job weighs over 7 tons and is over 14 feet long.

Another photo but from a different angle
of the transmission case being realigned
This shows what our
T/700 hydraulic unit looks like with the remaining electronics removed
and our EXTREME valve body fitted.
It take's two days just
to paint the transmission with two coats of under coat and two of
gloss black.
This is a photo of one
of our EXTREME T/700 hydraulic units that has been fitted with a
Nissan Patrol adaptor unit.

Another photo of one of our Extreme 4
wheel drive T/700 adaptations but this time we picture an 80 series
Toyota Landcruiser transfer case bolted up to one of our T/700
with our new inhibitor switch kit mounted to the side
of the transmission.

All of our Extreme transmissions come
standard with Kilm Bronzed and Micro Balanced convertors
EXTREME
T/700 convertor that has been double kiln bronzed, heavy duty
bearings and balanced.
We have both a lock up and non lock up
version of this convertor.
