In Kev's reply to which you referred, he appeared to me, to be suggesting a likely problem with the gear selection that is not unknown on the standard set up.

In your original reply you said "The proper gear box is hydraulic" which I misunderstood to mean you were suggesting that the gearbox operation was hydraulic, rather than the clutch operation.

I do however wonder how a leaking master cylinder could stop any gears being available, unless of course the fluid reservoir is used for box and clutch operation and the leak has allowed the level to fall below operational level.

If the hydraulics are unable to fully disengage the clutch then I am sure there will be an inhibitor somewhere that recognises that to ensure that no attempt is made to try and engage any gear.

Its not the destination that matters.

It's who you share the journey with (even if like me, it’s in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with

The gear selection is hydraulically driven on the Comformatic. The final selection is of course mechanical but there are two fluid reservoirs for the gearbox/clutch operation on the Comformatic. They are completely separate from the brake master reservoir which is shared with the clutch on the manual box

Phew all sounds to be way too complicated to me, why not just fit a slush box and be done with it, or stay with manual.

I replaced the clutch master cylinder and still have a problem.I can now engage gears with the
ignition on,but when I start it I get the `no gear available` warning.

Once you have had a manual you wouldnt want to go back to a manual!

I would, just think manuals are less issues in the long run, of course if you change your MH every 3 years or so and get a new one then it wont matter so much.

Spoke to someone whose firm runs a fleet of 25 Fiat comfortmatics, 22 of them have had problems, some very big ones.

They wouldn't have had those issues with a manual.

Maybe the error code needs clearing? Graham
