Hey guys.... i seem to be having all sorts of problems with my auto box in my 91 TT.
To begin with im getting the "ect / od off" error code turning on after 3 minuets of driving.
However more concerning is that when im stationary and i move the selector into drive the car doesn’t begin to roll itself forward, this has only started to occur recently and doesn’t happen all the time however i fear its a sign of something pretty bad. If it does pull its self forward its at a really slow rate. Reverse is fine however.
I have done a transmission flush which seemed to smooth the shifting out a bit however the problem still remains.
I should also note... whilst its probably un-related on the odd occasion recently, early in the morning while the car is still cold I drive to the round-about at the top of my hill and the car cuts out.... it basically just stalls, it doesn’t choke and splutter, it just turns off... could this have anything to do with it?
Any ideas? |

These motors dont like to be run whillst too cold. ALways best to warm them up as they have a fail safe in the ecu that when the temperature is till cold, if the ecu detects too much boost while cold, it will cut out ( Correct me if im wrong someone as this is what iw as told, not that i have experienced it) Its a failsafe to stop extreme wear and tear on an unwarmed up engine. |

good point daniel... altho i do give it a minute or so before i drive off and even then i dont take it over 2500rpm till the temp gauge hits half way. how long is a good warm up?
anyone have any ideas regarding my first problem? |

if the car doesn't roll forward, maybe adjust the accelerator cable? |

Do the transmission error test and see what codes you get. Maybe a solenoid has stopped working and its not going into 1st gear? |

Almost certainly a faulty solenoid. The flashing O/D off light is the classic indication of this.
Not sure about boost limiting when cold but the ECU will hold the auto in lower gears longer and prevent O/D engagement when cold. |

Is it safe to just keep the revs under 2000rpm when the engine is still cold? Sometimes I don't have time to warm up the engine, so I just drive heaps slow til the gauge hits halfway. Even then, I give it an extra 10 minutes or so before I start driving normally. |

Thats what i do every day Vinh.
I have been doing it since i bought the car and all seems sweet so far. I usually dont touch the pedal; just let the idle do its work =P |

It's probably better to be driving quietly than sitting idling, as the gearbox, diff, and other moving parts also start to warm up.
Depending on what you mean by driving normally, but just fitting in with the traffic should be fine. |

No point in idling a modern car in the morning to warm it up. It's a waste of fuel and as Peter says, it does nothing for the drivetrain. Just take it easy - you won't be doing any damage if you stay under 3000 rpm and drive smoothly. |

I just let idle for about 40 seconds or so until the idle drops to 1000rpm, then let it roll down the street (its a hill) and drive below 3000 until i get to uni which is 5kms away. Gets to half way mark by then. |

Well I just normally drive it without letting it come on boost. My eyes always on the boost gauge when I'm driving in the morning. I see my idiot friends with their s14's hitting 4000rpm when they just got into the car, lol. |

Hi,
Your first problem, the ECT error message is only a faulty solenoid. I'm guessing when you hit the OD button the message goes away? if so.. that's a pretty obvious indication (which is good news !)
Second problem, when you say turns off, does this include your dash etc? or does it flick into "charge" ? |

I had this problem for months and months. I took it to my mechanic and he told me it was a falty solinoid. But after he had the car for a while he noticed it was slipping slightly. (see i never noticed it was slipping cos it was like that when i brought the car) He then said cos your car is slipping the ECU is picking this up then bringing on this ECT error code. He was right cos after a good thrashing for a while second gear was slipping its arse of.
also my O/D light was flashing.
Well thats my story lol I hope everything works out |

Mine had the ECT error on the dash with the o/d light flashing and it ended up being a faulty capacitor in the ECU - go figure |

Not a hell of a lot as I recall Hayden, one of the simpler jobby's on a Soarer |

Don, can you ellaborate slightly on this "involvement in Solenoid replacing"?

Drain transmission, remove pan, remove strainer, unplug solenoid, remove solenoid, replace solenoid, plug in solenoid, replace strainer, replace pan, fill transmission.
I may have skipped something, but that's about the gist of it. |

dont know if this helps but if your car isnt properly grounded (an extra cable from the battery seems to fix) it might cut out completely when a lot of electricals are running (maybe in the morning when you might have demisters, heater/fan going?) |

Steve, I think S&L are replacing my solenoids today. If they do I'll PM you the price they charged me as a guide. |
