Changing M/T OilECS008BR
DRAINING
1. Start the engine and let it run to warm up the transaxle.
2. Stop the engine. Remove drain plug and drain oil.
3. Set a gasket on the drain plug and install it to the transaxle.
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug. Fill with new oil until oil level reaches the specified limit near filler plug mounting hole.
2. After refilling oil, check oil level. Assemble gasket to filler plug, then install it to transaxle body.
CAUTION:
Do not reuse gasket.
Checking M/T OilECS008BS
OIL LEAKAGE AND OIL LEVEL
●Check that oil is not leaking from transaxle or around it.
●Check oil level from filler plug mounting hole as shown in the fig-
ure.
CAUTION:
Never start engine while checking oil level.
●Set a new gasket on the filler plug and install it on the transaxle.
CAUTION:
Do not reuse gasket.Drain plug:

CLUTCH AND BAND CHART
●*1: Operates when overdrive control switch is set in “OFF” position.
●*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.
●*3: Oil pressure is applied to 4th “apply” side in condition *2 above, and brake band contracts.
●*4: A/T will not shift to 4th when overdrive control switch is set in “OFF” position.
●: Operates.
●A: Operates when throttle opening is less than 3/16, activating engine brake.
●B: Operates during “progressive” acceleration.
●C: Operates but does not affect power transmission.
●D: Operates when throttle opening is less than 3/16, but does not affect engine brake. Shift positionRever
