Gday guys. Ive got a vt l67 with decent cam and some go fast bits on it. Its Got a shift kitted standard 6 gearbox and a standard v6 torque converter. Was giving it abit of curry one night and it just made a terrible sort high pitched sound from the gearbox area and just came to a stop. Wouldnt move you could put it through all the gears but it wouldnt select anyway. Got it towed home. A couple days later got in it selected drive and i drove it around the block. When i give some berrys it still makes a bad sound. Can anyone tell me if it is just the torque converteror? Or should i just swap the gearbox and all. Cheers guys.
