Well Well - we are getting there. NNo just the analogy of things breaking but then there is the old adage -if it ain't broke don't fix it.

Maybe. But BMW simply specify their version of a basic design. From ZF etc if autos. The same basic box as used in many other vehicles. And these days the differences between them tends to be mainly in the software. ZF specify what the 'box can handle torque wise by the final two digits of the model number. 6 cylinder BMWs changed from the 5HP18 to 5HP20 when they increased the largest engine capacity from 2.8 to 3 litres. Of course it could be argued that overspeccing the torque handling capability of an auto will result in longer life. It might - but it also results in greater weight, size and cost. -- *When the going gets tough, the tough take a coffee break * Dave Plowman London SW To e-mail, change noise into sound. |

As I said Dan - we ENGLISH invented the language so we can do what we like with it unlike the French who are very strict with spelling and pronunciation and the Spanish who place the ? upside down but then that's not English - is it? -- Sir Hugh of Bognor The difference between men and boys is the price of their toys.
