Where is the drain plug for an orion 250cc gearbox? and how much fluid do i put in? can i get a service manual from somewhere?

'Transmission Fluid' in a manual transmission vehicle is called 'gearbox oil'. On the gearbox, there is a drain plug in the bottom somewhere and a fill plug on the side. You drain, clean the drain plug, replace the copper washer and put the drain plug back in. Fill the gearbox with oil until the oil starts to weep out of the filling hole. Replace the fill plug.

Manual gearboxes usually require a gearbox oil change every 30,000 to 50,000 mi (48,000 to 80,000 km). Automatic gearboxes usually have gear oil change intervals of between 60,000 to 100,000 mi (96,000 to 160,000 km). It's advisable that you change your gearbox oil filter at the same time as your oil.

Yes you can, but it is a messy and possibly problematic job. DO THIS WITH A COLD ENGINE AND GEARBOX! First you will need to find out how much replacement fluid you will need and you'll need to source the torque settings for when you put the plugs back in.
The whole car needs to off the ground. A car lift, a pit or axle stands will be needed. You will need something to drain the fluid into FOR SAFE DISPOSAL!! An oil drain pan is ideal.
On the gearbox housing there should be two drain plugs. One high and one low. You will probably need a specialist tool or adapter to remove the plug.
Remove the LOWER plug carefully and catch the draining fluid. Once drained, PUT THE PLUG BACK IN!!
With the bottom plug back in at the correct tightness, remove the top plug. Refill through this hole. Use a piece of hose and a funnel if it is difficult to get to. The refill amount is commonly to the point where the fluid will overflow from the fill hole.
PUT THE PLUG BACK IN!!
Clean everything properly. GENTLY test drive the car and recheck for leaks.

Hi,
We need more information. Type of Vehicle, year, is this manual transmission....etc. That being said, most "gearbox" have two 'bolt type plugs' on them. One to drain fluid out and one to put fluid in. Really need to know more about what you have.

Ok, so if your lucky you need to just have the fluid in your transmission. (if it's a manual anyway) If you want to give a shot at fixing it yourself. Go buy some lucas trans conditioner, cleaner or similar product, 7 quarts dex III mercon. Put the cleaner (transmission additive to dissolve sticky old trans fluid from parts) Run it for about a 100 - 300 miles, pull the drain plug on the bottom of the transmission, let it fully drain, then put the 7 quarts of fluid you bought earlier in. The light basically means that you are low on fluid or that a solenoid is sticking maybe. Since this is a manual gearbox there isn't any dipstick to check the fluid.check your manual for the suggested millage that you should service the gearbox. I would say 50k - 75k would be a safe bet unless you notice it has been leaking fluid, or that there is always a drop or two. Then it might lose enough to be low sooner then that. Don't just try to add fluid as there isn't anyway to tell if you overfilled it and that will do nothing to improve it's performance only add stress to the seals.
Sry about the delay on the answer, hope it helps.

I would try http://www.amazon.com it has tons of stuff for all type motorcycles.

Good luck

i accidently drained some of the gearbox oil from my bravo b2600 1997. where is the hole to put more fluid back in there? how much should i put? and what fluid should i use?

MOST MANUAL TRANSMISSION BEFORE CHANGING FLUID YOU DRIVE CAR AROUND.TO WARM THE OIL.SO IT WILL DRAIN OUT EASILY.NOW SAFELY RAISE VECHICLE AND SUPPORT IT ON JACK STANDS.LOCATE DRAIN PLUG ON DIFFERENTIAL PORTION OF THE CASE.GET SOME RAGS ON HAND.AND A DRAIN PAN.PLACE THE DRAIN PAN UNDER TRANSMISSION. REMOVE THE DRAIN PLUG.LET THE OIL DRAIN.WHEN FINISH.PUT IN NEW GEARBOX OIL.

If you have 1/8" to 1/4" freeplay in the clutch lever the cable should not be the problem. You had best check the gearbox oil level.
