GENERAL INFORMATION
(1) The combination of highest-precision electronic and mechanical technology heralds a new era in
automatic transmission performance.
(2) The gear shifting clutches use a hydraulic balancing mechanism to enable gear shifting at extra-high
engine speeds.
(3) The number of shafts has been decreased to two, increased use has been made of metal plates
and the one-way clutch has been abolished, which all contribute to reduce the weight.
(4) Increased meshing ratios and improved rigidity of the gear supports and casing result in less noise.
(5) The number of oil cooler feed tubes is increased to two.

DISASSEMBLY
Caution
1. Because the automatic transmission is manufactured
from high-precision parts, sufficient care must be
taken not to scratch or damage these parts during
disassembly and reassembly.
2. The working area should be covered with a rubber
mat to keep it clean at all times.
3. Do not wear any cloth gloves and do not use any
rags during disassembly. Use nylon cloth or paper
towels if you need to use something.
4. Parts which have been disassembled should all be
cleaned. Metal parts can be cleaned with normal
detergent, but they should be dried completely using
compressed air.
5. Clutch discs, plastic thrust plates and rubber parts
should be cleaned with automatic transmission fluid
(ATF) so that they do not become dirty.
6. If the transmission body has been damaged,
disassemble and clean the cooler system also.

REASSEMBLY
Caution
1. Never reuse the gasket, O-ring, oil seal, etc. Always
replace with a new one when reassembling.
2. Never use grease other than blue petrolatum jelly
and white Vaseline.
3. Apply ATF to friction components, rotating parts, and
sliding parts before installation. Immerse a new clutch
disc or brake disc in ATF for at least two hours before
assembling them.
4. Never apply sealant or adhesive to gaskets.
5. When replacing a bushing, replace the assembly
which it belongs to.
6. Never use any cloth gloves or any rags during
reassembly. Use nylon cloth or paper towels if you
need to use something.
7. Change the oil in the cooler system.
