Kickdown not working

[ladders]

Hi I drive a2.2 automatic z3. Took the car for a drive, on the way out I gave it the beans kick down behaved really well and revved all the way to just over 6000 revs.it has two throttle response settings, one approx three quarters down the pedal movement and the other when you hit the floor. I stopped for a pint on the way home got back in the car and neither pedal movements are working, it revs freely, but the oomph has gone. Have I broken it?

Took the car for a test drive and all is well it has got the oomph back, but never floored it to 6000 revs. I can only presume there is a protective overheating switch in the auto box, because the coolant temp gauge was showing dead centre.

Have you checked the gear box oil level?
Autos can do some strange things when the level is marginal and you have been showing it what for!

My independent mechanic has checked the oil level and for cleanliness.
