Before disassembling transmission, wash off dirt and other objects on it so that they will not get inside
of transmission during disassembly and reassembly.
Keep component parts in group for each sub assembly and avoid mixing them up.
Clean all parts with cleaning solvent thoroughly and air dry them.
Use kerosene or automatic transmission fluid as cleaning solvent.
Do not use wiping cloths or rags to clean or dry parts.
All fluid passages should be blown out and checked to make sure that they are not obstructed.
Keep face and eyes away from solvent spray while air blowing parts.
Check mating surface for irregularities and remove them, if any, and clean it again.
Soak new clutch discs and brake band in transmission fluid for 2 hours or more before assembly.
