I would suspect a fault on the engine somewhere before looking at the transmission. Try checking fuel pressure at WOT (wide open throttle) it may be the pump is loosing pressure or the fuel pressure regulator !

Thank you for your suggestion. The problem turned out to be a wrong sized tyre fitted to the front which caused problems with traction control and abs. Thanks again.
