It's a 2002 l322 . Gears have been playing up now I can't even get it to move a meter without it cutting out . Last night it went in limp mode . It did have a funny whining noise to it mabey oil pump ? The box has a bit of a leak at the tc. I've just tyred to fill the box up but only managed to get half a litre in it .



Any help much apreciated
Thanks
 
Trust you used the right procedure to check gearbox leve..?

Engine running, gearbox temp at 40degC, go through gears, back to park, fill till it dribbles.

Gear Ratio 2 error could indicate a slipping torque converter or burnt out clutch pack!
 
Yep I followed your helpful advice on one of your threads on how to fill the box . What the next step I need to do ? Take box out ?
Thanks
 
I've only had the car a couple of months but I've got a invoice for the tc done a couple of years ago
 
It's like it's slamming it in gear . Give it high revs and it helps a bit but just like chucks The car forward a bit more
 
No.....gearbox sounds fecked.....search on RANGEROVERS.NET HOME for posts by a guy on there called RRPhil (he is known as Bemble on here), the guy is a fecking genius when it comes to the L322 gearboxes...both ZF and GM....

If it bangs into gear, then the box needs and overhaul, nowt to do with the TQ on this occasion me thinks......

As for Battery undervoltage...mine does that, apparently as the voltage dips during the start process, the CANbus throws a low battery code.....mine manifests itself in the HID ECU's saying battery voltage >7.5V but (as the moment) I have no battery issues.
 
Quoted from this thread:

L322 Trans failsafe message and fuse 54

it’s engaging 4th gear when it goes into failsafe (i.e. standard limp-home setting) but when the 5HP24 has a problem with its A-clutch, for example, it actually selects 5th gear (usually with a bit of a bang). Is it possible to confirm whether it’s 4th or actually 5th gear that’s being engaged as this would provide further clues?

4th is geared at 23mph per 1000rpm engine speed (e.g. 2500-2600rpm at 60mph)

5th is geared at 29mph per 1000rpm engine speed (e.g. 2000-2100rpm at 60mph)

RRPhil (Bemble) is a genius on these things.....I advocate reading everything the man writes!
 
How much of a pain are these boxes to change ? I've done defender boxes befOre . But I'm no mechanic

And this one if you are bored

I've had the box out together with the transfer box which weighs similar to a small car and over Christmas i took out the transfer box on its own.

The most difficult part is the weight of the parts.

A very good mechanic friend helped me with the transmission removal and rebuild and i did the TB on my own apart from my neighbour helped put it back in which was a total bar steward without a transmission jack that you can buy for about £100 i realised after.

Without question, if you are doing this on your drive, you will need to raise the vehicle front and back enough to get the transmission out, recently I have done this by driving onto 4 sleepers but that was only to get the TB out, but you need considerable height to get the trasnmission out. we actually built some full length ramps.

Forget 4 axle stands ! The second issue is the amount of height you need to get the box out is the height you need to be able to raise the transmission to get it back in which sounds obvious and what might help would be to be able to raise and lower the vehicle.

Its probably easier to put the TB back on the transmission first but what goes against you is the weight and to be honest providing you have some decent extensions bolting the TB back on with the transmission that's already in ins't as bad as it would seem. The two bolts that you can access easier are the two at the very top, all the others are almost impossible to get anything other than the ring end of a 10mm spanner and an extension tube.

Honestly, i spoke to an auto box specialist who was going to charge me £1200 to remove the transmission, replace the torque converter and strip and rebuild the box and if you are not confident in doing it yourself, have a fair few tools and plenty of time, i would probably get it done at a garage, but make sure they use the correct oil for the rebuild.

I can get use of a ramp so that will make it easier. I've done land rovers by my self on drive before that isn't fun . Think I'm just going to buy a second hand box and put that in
