[broady18]

i wonder if anyone can offer advice, i recently lost a lot of automatic trans fluid via the oil cooler, having stopped the leak and topping up the fluid i now have a very bad vibration at high speed. have i damaged the gearbox beyond repair or is there a solution to this problem. any advice will be gratefully recieved. thanks broady18

coincidence, inspect the driveline and motor/trans mounts and go from there.
