4.8 Transmission Logic - Time to fix it or flick it

[LVR]

Well my 4.8 is a real Jekyll and Hyde type of car..... I hate it then I love it

After over a year of persistance I have finally had enough.

It is my daily driver and I am not one who roars around, although that should not mean that this %$%#&$%^*%^%^&*%^%^*%^$%#$@##$$ transmission logic defies my every need.

Each day I have a reasonable inclined road to drive up as I leave my work. From the lights the car is so busy dropping in to top gears that it hasn't noticed that I am going uphill and by now the thing is pinging (detonating) to high heaven.... and I am holding up the cars behind as I am actually slowing down.

All this from a big tough V8. Of course when I give it some more gas (usually lots to wake it up) it erupts in a blaze of sound and fury and next minute I am climbing all over the back of the car in front.

I have tried driving it in sports mode, but that is even worse. The change down points mean that I am doing about 4-5000 rpm in 2nd gear through a round-a-bout.... again a lot of noise for no reason.

There is a street on the way home that has a give way sign, meaning if clear you can continue. I approach it and come to a crawl, next minute it is winding out at 5500rpm in 1st!!!! and all I do is give it a GEEEEENTLE bit of throttle.

I am now switching between normal and sport mode depending on the location and type of corner I am at. What refinement!!!!

Oh, and don't even think of trying to plant the foot and overtake in a hurry...... by the time this big tough V8 has woken up to the fact that you want some squirt it's all over. Great to be all responsive after the event.....

I have had it reprogrammed by the delaer but it obviously learns bad habits all over again.

Can anyone......ANYONE PLEEEEAAAASE suggest a cure before I go and trade this thing in for something else.
