What is the average life of 2003 td6 transmissions?
People talk about 100k miles average brakedown.

Oil change time?

the transmissions start to break down at that time because there is a flaw in the design of the radiator, changing your oil wont help if your transmission cooler lines are all fudged up with crud from the bottom of your radiator...

BTW the cooler lines are located below your radiator drain plug so more than likely a flush wont do it, if they are in fact clogged... if your going with the tranny oil flush then make sure your tranny cooler lines are clean too

The GM 5L40-E transmission used in the TD6 has a reputation for weakness in its torque converter lock-up clutch where the friction lining can break up and contaminate the fluid. This finds its way into the hydraulic valve block causing the transmission to 'fail'.

It would therefore be sensible to replace the fluid (use only Texaco ETL-7045E) and filter more often than the recommended 'never' so that the condition of the fluid being drained out can be assessed.

Unfortunately, however, new fluid will not prevent the LUC from failing. It would be very useful if anyone else with a TD6 who has had this problem could report at what mileage their failure occurred so that we can maybe build up a picture of how fair this reputation is?

If the coolant is changed regularly (as per the schedule) then there wont be a build up of sludge. Unfortunately LR doesn't always keep to its own schedule when you take the car in. Or the kid on minimum wage doing your coolant change sticks the wrong coolant in and then you get reactions between the coolants and sludge build up.

I don't think there is a set mileage ie 100k for the trans to fail in, but the manufacturer recommend changing the oil (cant remember the mileage something like 60K?), so not exactly the LR claim of sealed for life. So if you've done over 50k on the original oil then you could be causing damage every time you drive it.

A good idea for preventative maintenance is:

Change the coolant every year (for the sake of £15 for some antifreeze why wouldn't you) maybe the first couple of times you do it run a flushing additive through the system.
Change the Trans oil every 50K (cost me (£150 from a trans specialist inc labour and the correct oil)

When I changed the transmission oil I did it this way:
drained the transmission oil
disconnected the pipes from the radiator at the transmission
mounted off the sump
changed transmission filter
cleaned the sump
flushed new oil through the disconnected pipes trough the radiator both ways(both pipes). Then I would be sure the radiator and pipes would not be full of dirt...
fitted new gasket to the sump
mounted sump
filled with new transmission oil (as described in RAVE)

How hard was it to drop the pan? It is probably fairly heavy, did you have someone helping?
The pan/sump was not heavy, but you have to remove 25 bolts :crybaby2:

I changed tr. oil today at 60 k miles,the oil was black,there were no metals.
After change and engine and transmission software update gears are softer and acceleration is much better.
Service guy told me that some tr. oil is like new when opened at 80-90 k miles.

I am currently scheduling a transmission oil change this for my TD6.

It seems worth the £150 GBP if you can extend the life of your transmission!

From researching, it would appear transmissions fail compeletely at 90-100k as LR/BMW say the unit is sealed for life. 'Life' is a very vaugue term in my opinion :D , and I find it difficult to understand how having the same transmission fluid in a gearbox for the life of a car could do it any good!

P.S, if anyone could reccomend a transmission specialist in Berkshire, UK, this would be most useful :thumb:

Matt,
You r right about cost-gain thing.
You will probably experience smoother gear changes too.
I am not sure mine was due to reprogram or oil;i guess both played parts.

Just order my transmission oil with help from Dan :D

Just over £50 from britpart!

I am sure someone has mentioned this before, but I cannot seem to find the post - can anyone advise as to where I can purchase the transmission oil filter from? Would dingocroft do this? :think:

Thanks in advance!

If you Google the part number THE500031 you'll find a few people that sell them. This part number includes the gasket and screws and costs around £120 from a Land Rover dealer.

(Surprisingly, for the ZF transmission filter used in the petrol models, the LR dealer price is cheaper than the official ZF spares centres)
