Hi folks,I've got a 07 plate 2.7 diesel which is developing gearbox problems it makes a rumbling sound especially when going uphill. I've been told it might need a torque converter,then I was told by another party to just get new box,have a look on ebay..which I did ,and was left confused by the cost? Anywhere from 200 to 2000 quid!...so any help would be much appreciated. .thanks art
