Sounds like shift solenoid or line pressure solenoid.. that's if it's not going into upper gears even when you floor it, as that's what happened to mine.. only thing I can suggest is speak to JeffTT, he is the man with this kind of stuff.

It's such a shame this even happens, the only real fix, for the auto.. is removing it and doing the auto:manual conversion, and that's if you intend to keep the car long term, and to be fair, it would be hard to sell a ZX which wont move, so you're best off doing the conversion mate, that's what i've decided to do anyways... sorry to hear this though brett, I hope someone else can offer some other suggestions and that this wont put you off your Z!

done a auto dianostics cheak all looked to be ok dont no if the solenoid or line pressure solenoid would show up with that test like but i am goin down the manual conversion route but will have save cash up so me car will be of the road for a good while i carnt give up got to much money init she is stored away for now

Yeah, it sounds like we're both in the same boat where our gearboxes are concerned, I wasn't getting any faults from my auto diagnostics test either, but I just assumed that's all it could be since it wouldn't shift into 3rd.. so I doubted the ecu.. either way tho it's fooked!.. but i'm glad to hear you're still keeping the Z mate, Manual conversion is definately the one! :D
