Disco 2 Gearbox Solenoid

Hi I have a 2000 TD5GS Auto and last year had a problem with it going into Limp Mode. I took it in and was told, after much head scratching and people really not being sure, that one of the solenoids in the gearbox had gone. Eventually the problem was resolved and about three weeks later it was returned to me. The problem I have is that it really seems that the power is down. Prior to the gearbox issue it had really good pick up speed and the acceleration was fine. It now seems sluggish and when I try and accerlerate there is much noise and bluster but not really much performance. It has been a while and I am really not happy. Any ideas would be welcome. Thanks

Check the ATF level. You have to remove the gearbox sump to replace one of the solenoids.

Inside the sump, where ?

Hi Nigel, to check the autobox fluid level, forget the sump - that was a comment relating to what the garage may have done previously and you don't need to go there.

So, on a D2 autobox to check the oil level you need:

1. The car must be parked on level ground. Start with a cold engine, have some atf (Dexron III) ready for topping up, a Torx bit size 50 from memory and a trustworthy assistant;

2. Get under the car, locate the level fill plug and slacken slightly with the Torx bit but do not remove at this stage;

3. Get you assistant to put the transfer box in neutral, the main gearbox in P and start the engine;

4. Then ask the assistant to put the main gearbox into each postion, leave for a couple of seconds to take up drive, then move onto the next position - so P to R, R to N, N to D, D to 3, 3 to 2, 2 to 1 and then all the way back to P. This allows the 'box to suck the oil out of the sump and into the "gubbins" LEAVE THE ENGINE RUNNING;

5. Now you (underneath the car) can remove the oil/fill plug and wait to see if any oil comes out - if the level is correct a small bead of oil will drip out. If no oil comes out you need to top up with Dexron III until it does;

6. Once topped-up correctly, refit the level plug, turn the engine off and you're done !!!

I was interested because I have the exact same symptoms as SPORTZPICS. I have already changed the oil and strainer/filter but it is still not right as I get a lot of engine revving but not a lot of forward movement. I was just curious as to where, if at all, there is a solenoid that affects this situation.

Anyone ?

Try manual shifting rather than just leaving it in D. Same or different?

It is not likely to be a shift solenoid (usually pretty robust). More likely to be failing TC or pump or perhaps a blocked up governer.

Manual shifting does'nt make any difference. I'm leaning towards a failing TC, unfortunately
