Hi I have 2 Mazda 323's the one is a '92 and the other is a '96 I need to top up the gear box oil (both manual's) and am not sure how? I tried to pour it into were the speedo cable goes but it didn''t seem to work Mitch

hi.
if it leaking that fast, it sound like you have a damaged seal.
i would not recommend adding more oil as it will probably come out even faster when you are driving.
the safest option would be to tow the car to the garage, or even better, have it trailered in.

should be a level bung half way up gear box on left or right hand side
you remove bung and fill to that level gear oil goes into manual gearbox

Hi B,
Is your vehicle automatic or manual? If its automatic start the engine and leave it idling. With the engine running check the gearbox oil level on the transmission dip stick (the one with the red top) and make sure that the fluid level is correct. If not, top up through the same tube where the dip stick fits. Don't over fill. If the fault persists the problem will be inside the gear box with the clutch and drive bands having most likely been damaged. The best and most economical way of fixing the vehicle will be to look for and get a good second hand box and have it fitted.
If its manual there is a probability that the syncro mesh cone has worn out. To repair the box is not very economically viable, so I'd recommend the same as for the auto box. Get a good second hand box and fir that.

Looks like you have a leaks problem in your gear box. You'll need a clean hand pump to top up your oil. Make sure your pump is clean. In your gear box, there should be 2 ports ( fill and drain). Filling port located upper position while drain is lower.
Inject your oil and check your deep stick after run your engine for minutes. Repeat those steps till you get normal level of oil. Never exceed max level of your gear oil.

top of the engine?

im not aware of any manual cars that dont run the gearbox and the engine on the same oil.

according to my book,the speedo gear,on top of g/box,is used to check oil level.pull speedo cable out,youll c the oil level marks

1.remove speedometer driven gear
2. remove drain plug, and drain oil
3. fill trans, check fluid by speedometer gear, just above gear see F & L, oil level is between F & L
4. install speedometer driven gear

manual gear boxes do not have a dipstick , there is a bung plug on the side of the box , about 1/2 way up. to check oil level,umdo that bung plug the oil level is the bottom of that hole.when at correct level oil will just drip over the lip.

What do you mean "rooted" ?
Generally if a manual transmission is stuck in gear it points to one or several of 6 possibilities ( barring any damage to hard parts such as gears or shafts.)
1: Damaged shift linkage.
2: Worn clutch.
3: Faulty clutch slave cylinder.
4: Damaged fork assembly.
5: Damaged synchronizers.
6: Bad throwout bearing.

Be prepared for sticker shock when pricing repairs or parts !
Mazdas are not cheap to buy parts for or to work on.
( thats why I will never own one )

i have had the same problem all i did was top up the fluid in the gear box, its was a git to do but worked
