unfortunately toe only way to top up/re-fill the auto-trasmission on a disco 300tdi is through the dipstick tube, can be a long drawn out process as you have to wait for the fluid to go down before continueing filling.
It is important to know the types of fluids that go into different cars. A Land Rover Discovery takes Dexron III automatic transmission fluid.
where do I put trasmission fluid in landrover discovery 2
Dextron III ATF
If a 1993 Land Rover Discovery is stuck in a low ratio gear, check the transmission fluid levels. If the fluid levels check out okay, the transmission may be experiencing a jammed gear.
ATF Dexron IID or Dexron III
there isnt one. theres a plug on the side of the trannsmission.
The automatic and manual gearboxes in series 1 and 2 Discovery both use dextron 3. Discovery TD5 uses MTF94 fluid and can only get it from Land Rover dealers or specialists. I believe there is not a compatible alternative.
According to everyone I have talked to (many mechanics), Land Rover has it's own transmission fluid that it requires for its vehicles. And, it is only sold at the dealership. I was told by my Napa Auto parts guy that Amsoil produces a synthetic transmission fluid that will work.
On non dipstick type transmission you cannot check the fluid level directly, but there is a bolt front of the transmission sump, unscrew and you can refill to that level.
To check the transmission fluid level on a 2001 Land Rover Discovery, start with the vehicle on a level surface and the engine running. Locate the transmission dipstick, which is usually found near the rear of the engine bay, and remove it to wipe it clean. Reinsert the dipstick fully, then remove it again to check the fluid level, which should be between the "hot" marks if the engine is warm. If the fluid is low, add the appropriate type of transmission fluid through the dipstick tube.
The amount of transmission fluid a Land Rover Discovery requires can vary based on the model year and engine type. Generally, it can range from approximately 8 to 12 quarts (7.6 to 11.4 liters) when performing a full fluid change. It's important to consult the owner's manual or a service guide specific to your model for the exact specifications.
on a 200tdi and 300tdi there is a little square pot at the back left hand side of the engine bay. The pot is see through. on the side of it there are 2 lines, a minimum and a maximum line. Using DOT 4 brake fluid to top up but do not exceed the maximum line.
