A/t Light...

[noely1]

Hey guys was cruisin round the city in Brisbane tonight with some of the boys and was stopped at a set of lights.. Lights went green and i put my foot down to go and it jus prety much sat there looked down and my A/T light was on...

felt like the car was constantly stuck in top gear just had no power wud hav it flat to the floor trying to hit 50klm's...

car was in tiptronic mode at the time and the display showed it was in 1st gear and i shifted to second third fourth etc didnt make any difference jus kept at the same speed and revs wud not climb...

anyway got it to a servo in time took like 10mins for a 5min drive lol stopped the car... started her again the A/T light didnt go out straight away it sat there flashing a few times then went out... so i stopped it and started again the A/T light went out as per usual this time..

I told my mates to get out of the car and check for any fluids ther was no leaks or nething so i started her once again and yet again the light went out as per usual so i risked it and drove it down the road for a little test and it shifted perfect didnt miss a beat...

what do you reckon just a computer malfunction or should i be worried??

Car is 1998 R34 (auto) 4dr... done like 80 XXX klms only

i had this problem with mine to ages ago!! (r34 auto). If you run a diagnostic i think it should come up as one of your solenoids is faulty or something along those lines? I'm pretty sure you'll have to replace it then you should be sweet!

solenoids help the car go into gear and will crunch if faulty or worn (could be the issue but the gearbox light wouldn't come up for this. Its suspect an electrical problem. When you have a auto car and you put a manual gearbox in, if you don't change the ECU to a manual ECU and get rid of the auto one the car will go into 'limp mode'. The car is sluggish and cannot get over 50km\h. Its defiantly an electrical problem that your car is having because it has gone into limp mode. have a diagnostics test run on it (it my have just been a short and wont happen again).......

well.. it did for me

anyways, just run a diagnostic.

defiantly needs a diagnostics test.

It's the solenoids, yes they have a very clever ECU that detects when the coils in the solenoid go open-circuit at operating temp, locking you in 3rd gear.
