If the oil pressure is not within the specified range, check and repair as described in the section "Preliminary Steps If Oil Pressure Is Not Normal" on the next page.
Trouble symptom |
Probable cause |
Remedy |
*Line pressures are all low (or high). NOTE
*"Line pressures" refers to oil pressures 2,3,4,5,6,7and 8 in the "Standard oil pressure table" on the previous page.
|
Clogging on oil filter |
Visually inspect the oil filter; replace the oil filter if it is restricted. |
Improper adjustment of oil pressure (line pressure) regulator valve |
Measure line pressure 2 (kickdown brake pressure); if the pressure is not the standard value, readjust the line pressure, or if necessary, replace the valve body assembly. |
|
Sticking of regulator valve |
Check the operation of the regulator valve; repair if necessary, or replace the valve body assembly. |
|
Looseness of valve body tightening part |
Tighten the valve body tightening bolt and installation bolt. |
|
lmproper oil pump discharge pressure |
Check the side clearance of the oil pump gear; replace the oil pump assembly if necessary. |
|
Improper reducing pressure |
Improper line pressure |
Check the 2 kickdown brake pressure (line pressure); if the line pressure is not the standard value, check as described in item 1 above. |
Clogging of the filter (L shaped type) of the reducing pressure circuit |
Disassemble the valve body assembly and check the filter; replace the filter if it is restricted. |
|
Improper adjustment of the reducing pressure |
Measure the 1 reducing pressure; if it is not the standard value, readjust, or replace the valve body assembly. |
|
Sticking of the reducing valve |
Check the operation of the reducing valve; if necessary, repair it, or replace the valve body assembly. |
|
Looseness of valve body tightening part |
Tighten the valve body tightening bolt and installation bolt. |
|
Improper kickdown servo pressure |
Malfunction of the D-ring or seal ring of the sleeve or kickdown servo piston. |
Disassemble the kickdown servo and check whether the seal ring or D-ring is damaged. If it is cut or has scratches, replace the seal ring or D-ring. |
Looseness of valve body tightening part |
Tighten the valve body tightening bolt and installation bolt. |
|
Functional malfunction of the valve body assembly. |
Replace the valve body assembly. |
Trouble symptom |
Probable cause |
Remedy |
Improper front clutch pressure |
Malfunction of the D-ring or seal ring of the sleeve or kickdown servo piston. |
Disassemble the kickdown servo and check whether the seal ring or D-ring is damaged. |
Looseness of valve body tightening part. |
If it is cut or has scratches, replace the seal ring or D-ring. |
|
Malfunction of the valve body assembly. |

Replace the valve body assembly. |
|
Oil pump gasket or seal ring (2) damaged. |
Disassemble the transaxle itself and check whether or not there is wear of the front clutch piston and retainer inner circumference, or damage of the D-ring. If there is any wear or damage, replace the piston, retainer, D-ring and/ or seal ring. |
|
Improper end clutch pressure |
Malfunction of a D-ring, seal ring of the end clutch or O-ring of the pipe (Refer to the following figure.) |

Looseness of valve body tightening part. |
Tighten the valve body tightening bolt and installation bolt. |
|
Malfunction of the valve body assembly |
Replace the valve body assembly. |
|
Improper low-reverse brake pressure |
O-ring between valve body and transaxle damaged or missing |
Remove the valve body assembly and check to be sure that the O-ring at the upper surface of the upper valve body is not missing or damaged; install or replace the O-ring if necessary. |
Looseness of valve body tightening part |
Tighten the valve body tightening bolt and installation bolt. |
|
Malfunction of the valve body assembly |
Replace the valve body assembly. |
|
Malfunction of the O-ring of the low-reverse brake piston or the O-ring of the retainer (Refer to the following figure.) |
Disassemble the transaxle itself and check the O-ring for damage; replace if there are cuts, scars, scratches or damage. |
|
