Hi I have a 2002 td6 that has started shuddering/juddering at 30mph and around 1500rpm, I recently had the gearbox oil changed and was fine. But a month or so later feels like I'm driving over a cattle grid ! have got new front arms and ball joints plus rear hub bushes to fit this weekend. Really hoping it's not the torque converter but after research on here looks like it is 😱 Is there any other things I need to check before I get it booked in to have a torque converter fitted ? Only seems to happen at 1500rpm and goes when you accelerate more, any help would be greatly appreciated as its really not been my month with the rr

Check front calipers, are the wheels hot to touch.? They are undriveable if binding.
