marzman Posted June 3, 2009 Share Posted June 3, 2009 Hi all, I think there's something up with my zed. Its happened 4 times now in the last 2 weeks... twice in the last 2 days! I have an automatic, and when driving in auto-mode it changes up and down gears when your revs get to a certain point. You dont know which gear you're in though, so its hard to diagnose where exactly this problem occurs. Whats happening is when im going slowly but in a high gear, say 15mph in 4th, usually up hill, the car is not changing down a gear when it normally would. I have to press the throttle to make it rev in order for it to recognise the load and change gear. What happens if i dont do this is the revs drop very low, the gear lever shakes, and the car come close to stalling. This only happens for 1 or 2 seconds max though before changing gear. Even worse, today when i pressed the throttle to make it rev - the throttle travelled about half of its length before it registered input! Also i dont know if im imagining it as im listening out for every noise at the moment, but it feels like its struggling to go up hills, as if its lost torque. As i said, this has only happened 4 times so far, lasting at most 2 seconds each time, but its cause for concern i think? Im thinking throttle position sensor may be something to do with this (i dont know WTF this is, but it sounds like it could be related!), but could it be the auto-box or do they have a clutch or something? Cheers. Quote Link to comment Share on other sites More sharing options...
sunset350z Posted June 3, 2009 Share Posted June 3, 2009 Ok i don't know anything about this, but if that was my car the fist things i would try is an ecu reset, followed by a change of oil in the auto gearbox. It may well be low of oil so check that first. If that fails then take it to a specialist. Or someone else on here may know exactly whats wrong with it. Lets hope its an easy fix Quote Link to comment Share on other sites More sharing options...

It may well be low of oil so check that first. If that fails then take it to a specialist. Or someone else on here may know exactly whats wrong with it. Lets hope its an easy fix +1 on both issues. There is an ecu reset procedure and a throttle position reset procedure - see the guides section on here. I would also check the oil level - I had a lot of trouble with my previous car (not a Z) when a similar tiptronic box failed due to lack of oil.
