My auto transmission gearbox shows the correct level on the dipstick when it is cold, but no level when the engine is hot and running

When the gear oil is hot with the engine running, no oil is shown on the dipstick at all. It should show the oil level at the higher level mark on the dipstick

Depending on the car you have, this might be normal, as usually some models require to check the oil when it's hot, but engine off, others require the engine to be running. Each manufacturer has specific conditions and though they are similar, they usually are not quite the same. So read the owners manual carefully, or call up the dealer and ask them to be sure. If your model is meant to be checked while running and shows no oil on the dipstick, then probably the tranny's oil filter is clogged and not allowing a good oil return flow. Could also be a clogged oil cooler. Either way you will need to drain the oil from the tranny to be able to examine the oil filter located inside the pan, or the oil cooler located up front near the radiator usually. Best way to test the cooler for cloggin is by shooting some compressed air into it and check if it comes out ok on the other end, or if it seems to have less pressure coming out, or even giving you a hard time to hold the hose in there while shooting air. Although be careful if doing that, cause there will still be some oil in the cooler and shooting air in there will spatter oil all over the place, so get a rag or bucket handy to collect the oil and not get it all over the walls :P

Hello, I had replaced my transmission, But when i started slowing down just before i stop it would slam down into the gears

I take it you have an auto box? Have you checked the fluid level after driving for 20 mins to get the correct hot temp needed to check the box level marked hot on the dipstick.Do not use the cold level as this is the wrong way to check

I have 1984 Merced turbo diesel it cranks ,you hear it go in gear but in drive when I hit gas petal it doesn't move and doesn't rev up

You are empty of ATF (auto transmission fluid). What happens is you have two vaned plates running very close together. One plate is connected to the engine and the other is connect to the gearbox. In between them is ATF and it transmutes the power from one plate to the other. You have no ATF so there is no transmission of power. Look under the hood and pull the ATF dipstick as opposed to the engine oil dipstick. Top up to the correct level.

How do i check a volvo 850 turbo's transmission fluid? do i have engine running? off? in park or neutral? thanks

Check the oil level as follows:

Park the car on a level surface with the engine idling . Slowly move the gear selector lever through all the shift positions and then to position P. Wait 3 minutes before checking the oil level.
As the illustration shows, the dipstick has a COLD and a HOT side. The oil level should between the MIN and MAX marks. Wipe the dipstick with a clean cloth.

WARNING! The oil may be very hot.

Do not use rags that could leave lint on the dipstick. The transmission is topped up via the dipstick tube. The space between the MIN and MAX marks on the dipstick corresponds to 0.5 US qt. (0.5 liter). Do not fill the transmission with too much oil, since this can result in oil being ejected from the transmission. Too little oil, on the other hand, can negatively affect transmission operation, particularly in very cold weather.

A Cold transmission: oil temperature 105° F (40° C). This is a normal temperature for the transmission after idling for about 10 minutes. At oil temperatures below 105° F (40° C), the level may be below the MIN mark.
B Warm transmission: oil temperature 169° F (80° C). This temperature after driving for about 30 minutes. At oil temperatures above 190° F (90° C), the level may be above the MAX mark.

Fluid type: ATF Dexron IIE and Mercon.

2004 Golf 2.0FSI auto transmission, 77,000 kms, dealer serviced since new, one owner (my wife). Auto trans is slipping and not selecting gears/keeping gears properly. Is this a common problem? VW dealer...

Check fluid level first to ensure that there is enough hydraulic pressure for brake bands and clutches to engage fully. Have the engine running in 'park' and remove the transmission fluid dip stick. Check level, colour and smell: it should be pink/red with no hint of any burnt aroma. If it is tinged brown this is due to clutch surface material wearing away. The acrid over cooked smell will arise if the brake bands are continuously slipping and generating heat. If the level looks low top with extra fluid via the transmission dipstick tube (do not confuse this with the gearbox oil dipstick) VW is a popular make and there will be auto transmission specialists out there with extensive knowledge. It would be no harm phoning around to ask for them to give it an assessment and then to ask the cost of adjustment, overhaul, repair or replacement.

Transmission stuck in neutral (automatic) won't engage drive or reverse

first i would check the transmission oil, do this by starting the engine and leave it running, select all the gears (park, Reverse, neutral etc) then put it back to neutral, leave engine running then locate the transmission dipstick in the engine bay, remove and wipe the dipstick, replace then pull out again, if the oil is showing between the cold and hot marks then level is ok. I shoing lower or none, top up the oil level with automatic tansmission oil, keep rechecking the oil level as adding oil as to ensure it is not over full. will need to select all gears again before checking oil level again.
If the oil level is correct than quite likley a Transmission failure will require mechanic.

I assume you are referring to manual transmission. Taking the aged of your vehicle into consideration your clutch plate assembly need to be replaced (Clutch and pressure plate and thrust bearing) The first symptom of a clutch system worn to it limits is the slipping experienced. Any vehicle's clutch will wear down over time and will need to be replaced after a while. As a interim the clutch can be adjusted at the hydraulic servo that activates the clutch lever entering the gear box. Open the hood and look down to your right at the gearbox. Let somebody step on the clutch pedal and look for the movement where the servo activates the clutch lever going inside the gearbox. It is possible to adjust the pin that moves in and out of the servo - adjust to shorter length (Only a fraction of a inch). Get in to the car start it up and engage 1 st gear. Let the clutch out slowly. It should start to "take" within a inch from the lowest pedal position. If not shorten the pin a bit more. "Shortening" of the pin must be stop when a gap becomes visible between the servo pin and the lever going into the gearbox - no driving of the vehicle should then be undertaken as it will let you down at the next intersection.
