hey guys was at the drags 2 night and as I was reving through 4th gear 3/4 through the track and went to shift to 5th the gearbox would not change gears ? then on next run did the same thing and wouldnt shift out of 4th and actually dropped itself into 3rd redlining and wouldnt hit 5th ? then I put it in performance drive and as it got up 2 4th would just red line and not shift 2 5th ? anyone experienced this problem? car is running around the 350kw mark has 73 k on it with no previous gearbox servicing also gave it a highway squirt and when it revs through 4th wouldnt shift to 5th and actually dropped into 3rd again??? any help would b much appriciated thanks antonio

I did a long 1,000k drive over the long weekend. Mines did something similar, except in third gear.

Just wouldn't change to fourth

I've had mine serviced about 10,000k's ago too :bangcomputer:

why are you changing to 5th at the drags?

4th easily gets you to the line.

Maybe on a stocker ... but with 350 at the wheel he's gonna need 5th ...

I'm with paulie, let it cool down and see if it behaves itself

and get the bloody thing serviced!!

Hate to be the bearer of bad news, but I would say your gearbox is stuffed. :bangcomputer:

My gearbox was doing exactly the same thing, apparently it was slipping badly.

From what I was told, basically there are 2 sensors, one on each end of the gearbox, and if they detect more than 5% slippage the gearbox won't change gear.

Would that put it into limp mode?

The box is simply slipping with all that torque and as such will need some new clutch's and preferably upgraded to handle the 350kw you are shoving down its throat.

Once upgraded it will handle that 350 easily. as long as the tuner also knows how to set the trans setting in his tune.

there is no way he needs 5th gear...

should be crossing in 4th.

Are you positive its the 4th to 5th or is it 3rd to 4th??
