Hi everyone, my p38 has originally been an auto, someone at some point has changed it to manual, I have water coolant pipes going to the transfer box, coolant is leaking from a gap in the casing, my question is, does this need to be cooled ? Can I just link the coolant pipes together and bypass the box ? I'm only doing motorway work with this p38 about 100 miles, then it's parked up for 4 hours then driven back 100 miles. Would the transfer box over heat ? Are manual boxes cooler to run than auto's ? it would be the cheaper option than taking the box out, has anyone bypassed this and had any problems ? Many thanks, rich
