PFP:00001
ACS004NF

Do not reuse transmission oil, once it has been drained.
Check oil level or replace oil with vehicle on level ground.
During removal or installation, keep inside of transmission clear of dust or dirt.
Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts they are applied to.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
Be careful not to damage sliding surfaces and mating surfaces.

Precautions for Battery Service

ACS004NG

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

When control lever assembly is shifted to each position, make sure there is no binding or disconnection in
each boot.
●
When shifted to each position, make sure there is no noise, bending, and backlash. Especially when control lever assembly is shifted to 5th, 6th without pressing downward, check for bending.
●
When control lever assembly is shifted to 1st, 2nd side and 5th, 6th side, confirm control lever assembly
returns to neutral position smoothly.
●
In any position other than reverse, confirm that control lever assembly can be pressed downward.
●
With control lever assembly pressed downward, confirm that it can be shifted to reverse.
●
When shifted from reverse to neutral position, confirm control lever assembly returns to neutral position
smoothly with spring power.
●
