r(For the details of lubrication points and type of lubricants to be applied, refer to the illustrated index and various work Dro-cedure (such as Assembly/Reassembly, Replacement, Overhaul, Installation. etc.) contained in each section,
*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper addtuves.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.*3: Always use Genuine Honda DOT 3 B.ake Fluid, Using a non-Honda brake fluid can cause corrosion and decrease thelife of the system.'4: Always use Genuine Honda Power Steering Fluid-V or S. Using any other type of power steering fluid or automatictransmission fluid can cause increase v,/ear and poor steering in cold weather.

Select the prcpe( 72 mm thrust shim from the chart
by using the formula below.
NOTE: Use only one 72 mm thrust shim
Shim Selection Formula:
From the measurements you made in steps 4 and 5:
- 1. Add distance @ (step 5) to distance @ (step 4).
-2. Frcm this number. subtract 0.93 (which is the
midpoint ot the flex range of the clutch housing
bearing spring washer).
-3. Take this number and compare it to the avail-
able shim sizes in the chart.
