We are back to the trans overheat messages and theh are more frequent and seem totally random. I have to check the resistance value of temp sensor but not sure if it will give me a clue as the fault comes intermittently. I am asking if the harness from a bmw, say 2002 x5 ,would be the same as ours and possibly a more favourable price. Island 4x4 is 138£. Plus shipping/import charges. Any experience shared will be gratefully received as the message comes up numerous times before trans oil temp has gotten anywhere near its danger point. I am wondering if those downshifts contributed to breaking the main drum snap ring location twice even though they were both the updated versions.
