Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.

Line Pressure TestS7RS0B5104016
Purpose of this test is to check operat ing conditions of each part by measuring fluid pressure in fluid pressure line.
Line pressure test requires the following conditions.
• Automatic fluid is at normal operating temperature (70 – 80 °C / 158 – 176 °F).
• Fluid is replenished to proper level (between FULL and LOW on dipstick).
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks against wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pr essure check hole in transaxle case.
Special tool
(A): 09925-37811-001
CAUTION!
After attaching oil pressure gauge, check that no fluid leakage exists.

4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
CAUTION!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one minute before performing another line pressure test.

Automatic Transaxle Unit AssemblyS7RS0B5106060
CAUTION!
• Automatic transaxle consists of highly precise parts. As even flaw in small part
may cause oil leakage or decrease in
function, check each part carefully before
installation.
• Clean all parts with compressed air. Never use wiping cloths or rags.
• Before assembling new clutch or brake discs, soak them in automatic transaxle
fluid for at least 2 hours.
• Be sure to use new gaskets and O-rings.
• Lubricate O-rings with automatic transaxle
fluid.
• Apply automatic transaxle fluid on sliding or rotating surfaces of the parts before
assembly.
• Use Suzuki Super Grease “C” to retain parts in place.
• Be sure to install thrust bearings and races in correct direction and position.
• Make sure that snap ring ends are not aligned with one of cut outs and are
installed in groove correctly.
• Do not use adhesive cements on gaskets and similar parts.
• Be sure to torque each bolt and nut to specification.

1) Install new manual shift sh aft oil seal to transaxle
