I'll be driving normally and then I'd go to push the accelerator down and it will just rev like its in neutral, then it will kick back into gear! Ive checked the Trans Oil and it seems okay, any other ideas as to why its doing this? Its not a consistant thing it happens every now and then.

Cheers

Loss of drive.

Low transmission fluid level. (Add 1/2 L and see if it improves)

Buggered gearbox, diff, driveshafts.

Get a trans guy to look at it.
