Well if that's the case it's doing a very good job of masking it for 20,000 miles!

.... If I recall correctly the max temp. spec. for the 5HP24 is 200 degrees. If the transmission temp is above that during normal driving something is not working properly.

This is were we could really do with a sample of temperatures to see if my findings are normal or not. 200 degrees F is 93 degrees C which is 2 degrees under where mine started acting up.

Yes, I bought it primarily as a tow vehicle - I just enjoyed driving it that much I ended up using it more and more as a daily when I fancied a change from my 330d.

As I mentioned further up the posts - it would probably have been a transmission out job anyway as I'd exhausted all other options. I've got a spare box with knackered clutch packs if it ever came to it but I'd rather I got as much mileage out of this box as possible if it is on it's way out.

All done when it went in for a torque convertor under warranty.
