Y62 Auto shift problems

[Bizz0853]

I'm no expert, but it sounds like a TCU programming issue. On my Compushift II, I can adjust all those sorts of parameters to make things happen when I want them to happen. Have you ever looked into TCU programming on the Y62?

I agree with you and do believe it may be a simple programming issue that is in place to protect the transmission, however I am astounded that the program kicks in during what I would quote as standard driving conditions. I would have thought that a 300kw V8 patrol would have been fitted with a transmission that would be near bullet proof or they would have had the common sense to lower the amount of torque available rather than jam the transmission in gear.I would be interested to hear more about this if I am unable to get my patrol repaired.

Hi, this is a TCU issue. There is a towing program available for the Y62. I had it installed in mine by infinitech motorsport Mackay.

I suppose you're still under Nissan warranty which means you probably can't change from specification fluid? Does your auto fluid look nice and red/pink, or brownish? If it's brownish it's cooked. I'd be asking an auto shop about the best transmission fluid for this problem. Is your oil cooler integrated into the main radiator (follow the pipes and see where they go)? If so you it might be better to add an additional loop to an oil cooler in front of the radiator. Gotta keep that fluid as cool as possible is my understanding.

at 40k the tranny oil is putrid

Forgive my inexperience of the 62. But doesn't it have tiptronic selection that will allow you to override the setting that being in D would enforce on you..
