Hi all I've recently bought a 53 plate sprinter 316cdi 5 speed auto not sprintshift. It seems to have a judder when chagging through the gears around the 38mph mark and worse when going up hills. From what I've read on here it seems to point to the glycol problem but after checking a few things this doesn't add up as the van was first registered on the 8th of jan 04 the radiator date is dec 03 and the make of the rad is BEHR which from what I've read should be o.k. Has anyone got any ideas please!!!
