Not tooconcerned about this but would be interested to hear of others' experience with this:

When cold, particularly in the morning, as I pootle along with a very light right foot, occasionally the box doesn't shift up on throttle lift-off as it would when warm. This happens at between 20-30mph, driving in second gear, lift off the throttle, and the car stays in second gear.

Is this purely because the box is cold?

I have also noticed after a good run and everything is warmed up thoroughly that when stationary the box clicks a lot when selecting different gears. Is this related?

Like I say, not concerned as everything still operates as normal and no other signs of things going wrong, no leaks, no AT transmission light.

Thoughts?

cheers

Cold oil affects the performance of the gearbox. The top gear lock-up clutch is programmed not to work until the oil reaches about 20C, to help warm the oil quicker: the "slipping" torque converter creates heat.

Ahh, most interesting, thanks orienteer :)

I am just reading the manual on the gearbox (thanks Don, KING of parts diagrams!)

Mine is just the same with "delayed" changing for the first few miles when cold.... can't say as I have any clicking when hot though.
