This asian Car has no dipstick on transmission / gear box. Instead, it has two holes bottom and upper bolts. The lower bolt is the drain plug and the latter is filling bolt. How we know the filling level then? Just tighten your drain plug and fill it with gear oil until it going flooded a bit. Then tighten your filling plug.

Manual transmissions use gear oil, not automatic transmission fluid.
There will be a filler plug on the side of the gearbox. The gear oil should be filled up to the very bottom of the filler plug hole.

Manual Transmission
The level of lubricant in the transmission should be maintained at the filler hole on all manual transmissions. This hole is on the right side. When you check the level in the transmission, make sure that the vehicle is level so that you get a true reading. When you remove the filler plug, lubricant should run out of the hole. Replace the plug quickly for a minimum loss of lubricant. If lubricant does not run out of the hole when the plug is removed, lubricant should be added until it does. Replace the plug as soon as the lubricant reaches the level of the hole.

DRAIN AND REFILL
Remove the drain plug which is at the bottom of the transmission. Allow all the lubricant to run out before replacing the plug. Replace the case with the correct viscosity oil. All manual transmissions use SAE 75W-90 API quality Grade GL-5 gear lubricant. Tighten the fill hole plug to 27 ft. lbs. (37 Nm).


I hope help you with this (rermember rated this help) Good luck.

No dipstick...you verify by havin car first on level ground then.Then when on stable ground remove the 17mm filler plug on upper passenger side of transmission.if fliud flows out of filler plug than level is fine.if does not flow out whenplug removed.RECOMMEND STRONGLY using a honda brand manual transmission fluid in this transmission..it does wonders for shifting or gearing issues.

Front Differential Oil Change

1. Before changing or inspecting oil, be sure to stop engine and lift vehicle horizontally.
2. With vehicle lifted up, check leakage. If leakage exists, correct it. NOTE: Whenever vehicle is hoisted for any other service work than oil change, also be sure to check for oil leakage.
3. Remove oil filler plug (2).
4. Remove drain plug (1), and drain old oil.
5. Apply sealant to thread of drain plug (1), and tighten it to specified torque.Tightening torque Differential oil drain plug a: 23 Nm (2.3 kg-m, 17.0 ft. lbs.)
6. Pour new specified oil until oil level reaches bottom of oil filler plug hole (3) as shown in figure. NOTE:

• Hypoid gear oil must be used for differential.
• It is highly recommended to use API GL-5 80W-90 gear oil.

Differential oil specification: API GL-5 (For SAE classification, refer to viscosity chart [A] in figure.)

Differential oil capacity (Reference): 0.9 - 1.1 liters (1.9/1.6 - 2.3/1.9 US/Imp. pt.)

1. Apply sealant to thread of level / filler plug, and then tighten it to specified torque. A: Sealant 99000-31260SUZUKI Bond No.1217G Tightening torque Differential oil level / filler plug b: 23 Nm (2.3 kg-m, 17.0 ft. lbs.)

I don't know if there is a fill plug. I just use the level plug located on driver's side right above the inner CV joint of the half-shaft (axle) to fill it. A piece of flexible tubing connected to a funnel works well. The drain plug is fairly near the center of the bottom of the gearbox housing (behind the bell housing). The level plug has a 24mm, fairly flat, hex head, and the drain plug is a recessed plug with a 3/8" (?) square hole (for a socket handle).

CHECKING FLUID LEVEL
1. With the vehicle on a level surface and the fluid in the transaxle cold, remove the filler plug and check the fluid level. The fluid should come to the bottom edge of the plug hole.
2. If the level is low, add SAE 80 manual transaxle fluid through the filler plug hole until the fluid begins to run out.
3. Reinstall the filler plug and tighten it securely. The speed gears and the synchronizer parts on this vehicle receive lubrication through specific passages in the mainshaft. It takes 1.8 liters (1.90 quarts) to fill the transaxle completely.
its located next to drive shaft some on left hand side others on right hand side depending what gearbox.

Look about 1/2-3/4 way up side of transmission for a square plug (5/8" wrench works if I recall correctly) Stick finger in hole to first joint, if oils there, it's o.k. if not fill until it touches tip of finger. I'm guessing that's not the problem, but let us know how it goes.
