Mercedes suffer with the radiator whereby the gearbox oil and engine coolant leak in together and cause gearbox to stay in lower gears like limp mode this will also give incorrect readings on coolant so worth getting both gearbox and coolant checked i beleive they call this a glycol test??

What would cause it to be stuck in third gear?

Some Vehicles have a seperate Electronic Control Unit for the gearbox. If there is a problem with the ECU or any electrical component inside the gearbox, i.e. pressure sensors or transducers the ECU will sence a fault which will limit the gearbox to either 2nd or 3rd gear assuming that the vehicle has an electronic gearbox. for this you will have to scan the OBD port with a scan tool... if it is an older vehicle, the gearbox will possibly work entirely off of pressure, in which case there might be a faulty seal or hose in the gearbox its self. Best to get it checked out by a licensed mechanic. This is not the kind of job you can do without the correct tools or knowlege

How to remove an ECU from an Audi multitronic gearbox

1. Jack the car up on Axel stands/ramps or if you have access to a pitit will make life a little easier. 2. You need to remove the splash guard underneath the car so you can seethe back of the gear box. 3. Drain the gear box of oil which will require a special tool which youcan get for £10 from Draper Expert 1/2 Square Drive Drain Plug Key For VW Or Audi63476 Draper Hdpk1. 4. Remove the electronic cable that connects onto the ECU that protrudesout the back of the back of the gear box. 5. The back of the gearbox has 12 torques holding the cover in place.Once you have removed most of them you will need to remove the rear enginemount to get at the last torque bolt at the top of the gear box. 6. Support the gear box with a trolley jack so you can lower the gearboxto get at the last few torques. 7. The rear engine mount can be slid towards the back of the car so youcan get at the back of the gear box. There is a couple of other bolts that youwill need to remove that hold the ECU cable in place. 8. Once you have all the torques that hold the gearbox in place thecover can be slid off. 9. Once the cover is removed be careful not to bend the metal gasket asit can be used again as long as it's not damaged (Audi would probably changethis along with the ECU seal). 10. Once the cover is off you can now see the ECU which is held in placeby 3 torques or Star bolts. 11. After the 3 torques have been removed you can then slide the ECU offbut be careful not to bend or tilt it as you remove it from the gearbox as ithas guide rails made of plastic which can break easily.

I have been told I need a gearbox rebuild. Car Audi A4 2002

Hi there. Your vehicle is fitted with an electronic automatic transmission and I suggest that before any expensive rebuild work is undertaken on the transmission, especially when you say it drives fine, it that the intermittent electrical problem is resolved. You should firstly have an authorised Dealer check out the fault codes on the transmission ECU – this might identify where the problem is. They will also be able to perform a ‘Stall Test’ and again this will determine the effective operation of the gearbox. Hope this helps, Scottech.
