Step 3.
Check clutch pressure (Appendix F, Transmission Pressure Tests, Section 7.3).
If clutch pressure is below 135-155 psi (930-1068 kPa) at 650 rpm, go to step 4.
If clutch pressure is 135-155 psi (930-1068 kPa) at 650 rpm, clutch faulty. Notify
DS/GS maintenance.
Step 4.
Check converter inlet pressure (charging pump pressure) at regulator valve (Appendix
F, Transmission Pressure Checks, Section 7.3).
If converter inlet pressure is not 150-195 psi (1034-1172 kPa) at 1800 rpm, drain
and flush hydraulic tank and screen (Appendix F, Transaxle Maintenance, Section
7.1).
If converter inlet pressure is between 150-195 psi (1034-1172 kPa) at 1800 rpm,
charging pump faulty. Notify DS/GS maintenance.
32.
TRANSMISSION LACKS POWER.
Check converter inlet pressure (charging pump pressure) at regulator valve (Appendix F,
Transmission Pressure Tests, Section 7.3).
If converter inlet pressure is not 150-195 psi (1034-1172 kPa) at 1800 rpm, drain
and flush hydraulic tank and screen (Appendix F, Transaxle Maintenance, Section
7.1).
If converter inlet pressure is between 150-195 psi (1034-1172 kPa) at 1800 rpm,
charging pump faulty, notify DS/GS maintenance.
33.
TRANSMISSION OVERHEATS.
Step 1.
Check level and condition of transmission fluid.
If transmission fluid level is low or fluid is burnt, replace transmission fluid (Appen-
dix F, Transmission Troubleshooting, Section 7.2).
If transmission fluid is OK, go to step 2.
