Well you can but it is a bit more difficult than that as you will need allignment tool to replace and also the might be excess tension and you might need a pulling tool also to remove. it is very unusual that the mechanism drops into the gearbox though? well without effecting the performance of gearbox such as whines and creaks?

    sounds more to me like you jhave some of ther mechanics missing from it fella? can be quite hard to place all working parts in correct order in ready for sealing again? as i say very unlikely it just dropped in as it has a small casting to sit on within the gearbox.

How much and type of gear box oil do I have to use in my mk4 golf, 1.6 litre engine transmission( gearbox)


Mark 4 VW Golf Manual Gearbox
VW has a specific blend of gear oil for that gearbox that you need to buy from VW dealer Parts department. If you cannot get it there, you can use a 75w-90 fully synthetic automotive gear oil .

The capacity is about 2.2 quarts (US) so ensure you buy enough.

If you are changing the gear oil yourself the vehicle must be level. Completely loosen or remove the fill plug first, to ensure you will be able to refill it ,before you remove the drain plug and drain the old oil out of the box. You will need a fluid pump in order to pump the new oil into the box and you keep adding the gear oil until it begins to run out the fill opening. It is full when it stops running out the fill opening so it is important the vehicle is level when you are doing this service.

You will need a good 17 mm Allen key to remove and refit the drain and fill plugs in the gearbox.
The fill plug is on the front left side of the transmission case while the drain plug is on the bottom by the dog bone.

Would like to know where the top up plug for my gear oil is and if there is a dip stick manual proton savvy bt 2006


Manual Transmissions don't have dip sticks.

2. Manual gearboxes have a drain and filler plug. The filler plug is usually found in an accessible position on one side of the gearbox which has to be accessed from under the vehicle.

To top up the gearbox the car has to be perfectly level so if you need to add oil to the gearbox you ideally need to get the car up on a garage hoist/lift so you can both access the filler plug easily, remove it and pump in the fresh gear oil. The usual correct oil level on these gearboxes is level with the bottom section of the filler plug opening in the gearbox. However you should check with the proton service staff on the correct procedure for topping up the manual gearbox in your car.

When clutch is engaged and you are changing gears there is a grinding noise kind of like a broken barring noise but that's not the problem, and it sticks when you change gears to 1st. We just did a...


sounds like the syncronizers are broken in the gearbox or it just may be low on gear oil all together.. check gear level by removing the plug in the side of the box under the vehicle and stick the smallest finger in the hole and bend down..see if fluid oil shows on fingertip..if not fill until it runs out this plug hole..there is also a drain at the base near the back tailshaft.. this is not a level check location.. it is a drain only.. if in doubt, get a towyard replacement trans gearbox and intall it in and it should work.. good luck

Transmission fluid smells burnt, trouble engaging gears


Hi Louie, When the ATF smells burned it usually indicates a problem inside the gearbox. Let's hope not though. Drain the ATF oil and then drop the gearbox oil pan. Remove and replace the oil filter and the pan gasket and then refit it. Fill the box with the required amount of transmission fluid. Once filled, make sure the park brake is fully engaged and then check the ATF level with the engine running and the shift in neutral selected. It should be at the top of the lower marks on the transmission dip stick. If the problem persists, the gearbox needs major work or replacement. Regards John

Where do i pour the new gearbox oil in when im replacing it on a 93 nissan 100nx 1600cc And where would i find a gti engine also


Is this an automatic or manual transmission? If automatic it goes into the transmission dipstick tube, if manual where is a fill plug under the car on the side of the transmission case. You will need a suction lube gun to put the gear lube into the manual transmission, fill to just below the fill plug threads. If auto make sure the transmission is hot to the touch before adding fluid, DO NOT OVERFILL EITHER TYPE OF TRANSMISSION, THIS GOES DOUBLE FOR THE AUTOMATIC GEARBOX.

Where and how do i fill gearbox oil ? (Nubira 99)


  • On the side of the transmission you will have two plugs. One on top and one on bottom. The top one is the fill and the bottom one is the drain.
  1. Put a drain pan under the transmission.
  2. Pull the fill plug (top) FIRST [always]
  3. Remove the drain plug.
  4. Let all the gear lube drain out.
  5. Replace the drain plug.
  6. Get a funnel with a little hose on the end of it.
  7. Put the end of the hose in the fill plug hole.
  8. Fill the transmission with the required type of transmission gear lube (see manual)
  9. Inset the fill plug into the fill hole.
  10. Job complete.

Regards, Tony

Where is the location on a 1994 honda civic ex that i would fill the manual transmission with gear oil?


Hello,
Manual transmissions have a fill plug and a drain plug on the side of the transmission. The fill plug is a little above the drain plug. Pull the fill plug and fill the transmission until the transmission fluid just barely seeps out and re-plug the transmission. That is the proper way to fill it. You will need a long stem funnel to give you the room you need to fill it. Your transmission requires a 10W30 weight motor oil, just like your engine. If you have a little time and 3 or 4 quarts of oil laying around you can pull the fill plug first and THEN the drain plug and let all the oil drain out. Then plug the transmission and re-fill it with fresh oil and this is a transmission flush for your transmission. You just saved $70 shop charge doing this. I say pull the fill plug first and THEN the drain plug because the last thing you want to do is pull the drain plug first and then find out the fill plug has welded itself and won't come out and now you can't fill the transmission. Fill plug first always.
Regards, Tony

What trans fluid is in 84 nissan pickup manual trans


No transmission fluid are ever used in manual transmissions.
Gear oils are used. And the specification is:
Gear Oil 80/90W

You would need to park the truck on a level ground in order to do this job.
Remove the filler-plug on the side of the gearbox, and using a hand-pump or a rubber hose, fill the gearbox with the specified oil. Once the gear oil starts to flow out through the side filler-plug, stop! The required quantity is reached.
Replace the filler-plug and start the car to check for leak.
Be careful so you don't accidentally get unwanted item in the bearbox.
