Disassembly
1. Remove the torque converter assembly.
2. Make sure all the oil is drained from the casing by
removing the drain (4, Figure 7-26) and screen (2).
NOTE: Stay clear of the transmission when removing the
strainer. Oil will gush out when the strainer is
removed.
3. Remove and discard oil filter (5).
4. Remove pressure switch (6).
5. Remove the speed sensor (7, Figure 7-27).
6. Remove the plastic water seals (8, Figure 7-28) to
reveal capscrews (9). Unscrew capscrews (9) and
remove reverse high/low clutch solenoid valve (10).
7. Similarly, remove the mainshaft/layshaft clutch solenoid
valve (11).
8. Similarly, remove the forward high/low clutch solenoid
valve (12).
9. When the solenoid valves are removed, remove and
discard the four O-rings (13) from each valve body.
See page 7-70 for solenoid valve repair.
WARNING
Certain seals and gaskets may contain fluoroelastomeric
materials such as Viton, Fluorel and Technoflon.
Fluoroelastomeric materials subject to high temperatures
can produce highly corrosive hydrofluoric acid. THIS
ACID CAN SEVERELY BURN.
New fluoroelastomeric components at ambient
temperature require no special safety precautions.
Use of fluoroelastomeric components whose
temperatures have not exceeded 300°C (572°F) require
no special safety precautions. If evidence of
decomposition (e.g. charring) is found, see the next
paragraph for safety instructions. DO NOT TOUCH
COMPONENTS OR SURROUNDING AREA.
Used fluoroelastomeric components subjected to
temperatures greater than 300°C (572°F) (e.g. engine
fire) must be treated using the following safety procedure.
Make sure that heavy duty gloves and safety glasses are
worn:
• Ensure that components have cooled then remove
and place materials into plastic bags.
• Thoroughly wash contaminated area with a 10%
calcium hydroxide or other suitable alkali solution, if
necessary use wire wool to remove burnt remains.
• Thoroughly wash contaminated area with detergent
and water.
• Contain all removed material, gloves etc, used in this
operation in sealed plastic bags and dispose of in
accordance with Local Regulations.
