Repair Instruction For Automatic Transmission Repair Manual: Precaution

BASIC REPAIR HINT

PRECOATED PARTS
1. Precoated parts are bolts, nuts, etc. that are coated with a seal lock adhesive at the factory.
2. If a precoated part is retightened, loosened or caused to move in any way, it must be recoated with the specified adhesive.
3. When reusing precoated parts, clean off the old adhesive and dry with compressed air. Then apply the specified seal lock adhesive to the bolt, nut or threads.

  NOTE: Do the torque checking with the lower limit value of the torque tolerance.
4. Depending on the seal lock agent to apply, there may be a case where it is necessary to leave ' it for a specified time until it hardens.
GASKETS
When necessary, use a sealer on gaskets to prevent leaks.
BOLTS, NUTS AND SCREWS
Carefully observe all specifications for bolt tightening torques. Always use a torque wrench.

TORQUE WHEN USING EXTENSION TOOL WITH TORQUE WRENCH

In case of tightening by extending the entire length of the torque wrench combined with SST or tool, if you tighten until the reading of the torque wrench reached the specified torque value, the actual torque becomes excessive.
In this text, only the specified torque is described. In case of using SST or extension tool, find the reading of the torque wrench by the formula.
Formula T'=T x L2/(L1 + L2)

FORMULA REFERENCE

T'	Reading of torque wrench {N.m (kgf.cm, ft.lbf)}
T	Torque {N.m (kgf.cm, ft.lbf)}
L1	Length of SST or tool (cm)
L2	Length of torque wrench (cm)
