Recently a red light flickered on my dash while on a long drive. Once I got home i looked it up and its apparently the High Temperature in the gearbox (little red F) anyway, paranoid I now hear a slight whine, I still use the old car regularly on long drives 500mile round trips and it continues to flicker for a bit then go out. I checked all the oils, diff, hubs and gearbox, transfer box and it all seems good.

I am now wondering what else to look for? could it be a faulty wire and sensor? If it is the gearbox, I have an old 3.9ltr V8 that I have stripped down. It looks the same gearbox (I would have to use the 300tdi bell housing is this possible? Only difference I can see is the V8 has an oil inlet and outlet to a cooler that sits under the radiator. Any help much appreciated, as it is my daily driver and is used for long drives. Thank-you/

has yours got a switch on the lhs rear of gear box,
 
James, thanks for getting in touch. Im not too sure I never noticed it when i was checking the oil levels but can get back under her for a look. Whats your thinking?
 
its on the other side ,some boxes have a switch on the transfer pipe ,or cooler take off , some have a switch in the lhs of transfer box not used here but wires are still hanging about
 
If it is a gearbox issue am i correct in saying the gearbox from a v8 will be a direct swap for the 300tdi one? they both look like R380?

no input shaft has a smaller spigot /spigot bush ,v8 19mm, tdi 22mm, you usually swap input shafts as well as bell housing
