The recommended fluid for manual transaxles is Honda Manual Transmission Fluid (MTF). As a temporary replacement, you can use engine oil labeled for SG, SH or SJ use. If using engine oil, make sure to use 10W-30 or 10W-40 viscosity; the 10W-40 viscosity is the safer recommendation, especially if driving frequently at high speeds for prolonged periods in hot weather.
See Figure 1
The transaxle fluid should be changed every 30,000 miles (48,000 km) under moderate to severe duty.
- Remove the oil level check bolt from the side of the transaxle. If oil runs out the fluid level is OK, retighten the bolt to 33 ft. lbs. (45 Nm).
- If fluid does not run out, the level is low. Loosen the filler plug and pour oil in slowly until it begins to run out via the level check bolt, then, tighten the bolt to 33 ft. lbs. (45 Nm) and filler plug.
DRAIN & REFILL
See Figures 2 and 3
- Raise and safely support the front of the vehicle.
- Place a fluid catch pan under the transaxle.
- Remove the upper and lower plugs, then, drain the fluid.
- Using a new washer, install the bottom plug tightening to 29 ft. lbs. (40 Nm). Refill the transaxle, until the oil is level with the upper filler plug hole. Install the filler plug and tighten to 33 ft. lbs. (45 Nm).
