Auto gearbox how do you check the gearbox oil level on a peugeot 406 automatic year 2000? thanks ricky.

low oil level in the sump and low coolant level in the radiator
could be excessive oil i the transmission
run the fault codes to determine other failures

What type of GB? Exact year/engine of your 307?
On most newer vehicles, you can't check GB oil level cause there's only the drain bolt. You must check in service/user manual how much oil is needed for GB (for manual GB it should be 2 ltrs).

The drain plug is situated on the final drive casing at the rear of the transmission (plug may need a square or hex drive wrench).

There is no level plug - the correct qty of oil must be measured and then poured in.
If Petrol 1.9 ltrs, diesel 2.0.

The oil is 75/80w.

That would be in your owners manual. Type in your cars year and model followed by PDF and hit enter

THE 5 SPEED AUTOMATIC TRANSMISSION

At the bottom of the automatic gearbox (tiptronic) you will find one threaded plug on below surface, (follow red arrow in the picture below). This is for emptying.




The oil level threaded plug is placed on the car front lateral automatic gearbox surface, (follow yellow arrow in the picture below).



The filling oil plug is placed on the upper automatic gearbox surface, (follow green arrow in the picture below).


Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Automatic gearbox oil capacity: 2,5 liter. Only ATF with VW designation may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: VW G 052 990 A2
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.

If you're not mecahnically minded, this isnt a job for you.
There is no filler cap for gearbox oil. The gearbox will have a level check plug, and a separte drain plug. Both will probably require a specific plug tool to remove (i.e. not just an ordinary spanner or socket), and can only be accessed from underneath the car.
Gearbox oil level has to be checked with the car level, so a garage will put the car on a lift so they can work underneath it. So, even if you jacked it up (never work under a car only supported by a jack ! Use ramps or axle stands as well) and could get at and undo the plugs, the car wont be level and therefore you wont put the correct amount of oil in.
Suggest you take it to a garage.

in automatic transmission box has two solenoids that were broken , so they must be changed , because I am peugeot specialist in Australia.

sometimes a nut comes loose behind the end cover on ml5 box.

Possible causes are; Low fluid level, bad pump, bad control valving, or a bad torque converter....accordianman
