GTC Auto Gearbox

[Boroboy]

I like how smooth it is as well but sometimes it doesn't change when I would.

Normal driving its great but when its cold to begin with its not as smooth as it can be but I can live with it.

The FTO would learn your town driving then your country driving.

I have contacted a few companies who have said they can improve the change time but I have decided this car isn't getting anything else done too it as I will be putting everything into my new project.

Bruce,
Mine is smooth. You could have it recalabrated by vaux, would expect it to cost you under an hours labour. My old box was lumpy, especially when cold. Some of the down changes were harsh too. After the new one was fitted & recalibrated it's as good as an auto box torque converter could be. I can get it to change at virtually any rev range. Just a case of lifting off the throttle slightly. I rarely use the manual function.
Even when I boot it. I tend to lift my foot off slightly so it does not rev over 4k.
I'd also change the box oil every 4 years or 40k. Not stipulated by vaux. As they say it's "sealed for life". I good Indy gearbox specialist said it was better to change it more frequently than that.
