Hi, I have a Nissan 200SX Turbo Automatic. It has a genuine 45k miles on the clock & has been well serviced & maintained & i love it to bits. Just recently i have started to have a problem with the auto box not changing into top gear but it only fails sometimes. If for example i join a motorway & floor the accelerator the car will accelerate hard but will not change into top gear. I also notice that the rev counter goes into freefall back to idle speed when i lift my foot off the gas rather than maintaining a higher RPM, this means that when you want to carry on accelerating or just get the power back on then the revs have to rise from idle to reach the road speed.There appears to be no engine braking at all. It doesn't do it all the time either, sometimes after gentle cruising i will want it to change to top gear & it wont. I have noticed that if i pull over & switch off then re-start everything is back to normal & it will happily change into top gear. I have no other problems with the auto box, everything else is as smooth as silk. Although the car has service history i'm not sure when the auto transmission fluid was last changed, i understand that auto boxes like a fresh oil change now & again, i have checked the oil levels & everything is ok. I also believe that this car has sensors linked to the auto box so maybe one of these is playing up which might explain why after a switch-off & restart everything is ok. Can anybody advise please of offer any input?...Or recommend an auto gearbox specialist near to Kent or South East London. Regards, Keith.
