I would like your opinion :

Would it be worth to replace your transmission cooler as preventive maintenance. Following the failure of mine, I found some reports on the net that the transmission cooler is a weak spot of the ZF boxes, not only in LR but in Ford and other cars that have this ZF transmission.

It sounds like the earlier transmission cooler have this issue and I read it is corrosion related.

When it fails the consequences can be substantial read the gearbox can fail. If you don't notice it in time (the leak) the coolant in the ATF can do serious damage to the gearbox resulting in massive damage i.e. full rebuilt or replacement.

So would you replace it ?? If I had known about this before the failure, I probably would have considered it. What about you guys. MY 2010 5.0 SC Galway green and sand interior!!

Replace! On the ZF box (4.4 petrol), ATF £10P/L, filter £10, new cooler £83. Got to be preferable to £2000+ for a box rebuild! Prob do it cheaper if you were carful and kept the fluid loss to a minimum and didn't do a total fluid and filter change while you were at it. [img]http://www.fuelly.com/driver/rob2529/range-rover[img/]

If something can't be fixed with a hammer....... You have yourself an electrical fault!

Depends on how long you keep the car for I suppose and the conditions it's in. In Lagos its clearly hotter than the UK (Most places are).

If its a cheapish and easy enough thing to do, maybe it's worth it.

I'm old school as well (raised by a true mechanical engineer driving British cars for most of his life, Triumph and Rover), preventive maintenance is the holy grail of long term car ownership and the best prevention of cold rainy nights waiting for roadside assistance or trying to fix it. MY 2010 5.0 SC Galway green and sand interior!!

On the 4.4 and SC why not replace the standard water-oil heat exchanger and cap the standard one off and mount a small unit using the fuel cooler and ducting from a TD6 instead? Could even wire a fan in series with the standard electric front fan if your that worried about it needing cooling or a small temp actuated sensor so that when it got to 95'c it would activate a fan. A standard 12v PC case fan should do the job if in slow traffic or slow speeds for such durations? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

That sounds like a potential plan KP, especially since high quality aftermarket coolers are easy to get from places like the US. If I had my tools and gear here, I would definitely do that. Here no chance, too limited in time, workspace and kit.

Now if someone smart, handy and entrepreneurial would come up with a kit that can be fitted relatively easily (Meerbusch ??), then I would consider doing it here, but for now I just go with original, hoping the new cooler is the improved version  MY 2010 5.0 SC Galway green and sand interior!!

If you know what the fittings are on the box for the output an the input and what the fittings onto a cooler would be and what angle they need to be then pirtek in the UK can knock them up while you wait and their knocked up stuff has never failed me or countless others in some serious applications  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
