Hi guys,
Just have a little problem, I have had coolant problems for the past 3 months, finally got it sorted out with a new bottle and bled the system, but everytime the bottle has been low on coolant, the car just sits in 4th gear doing 110K it wont drop into overdrive??
sometimes it did whenever i'd refill the bottle but now that the coolant is fine it still revs a bit high when i start the car and will not go into overdrive, you know when you turn the ac on the revs rise, well it';s like i have the ac on all the time, i get those revs, what is happening????

Does the trans need a service id it's a trans problem?
Don't see how the motor and coolant have something to do with this problem is it not just since you flushed the system another problem has come along? |
I'll show you the Rick James cell. It's superfreaky!. |

not sure was thinking because coolant was low and overheating that the transmission fluid was also and not letting it select overdrive

| yeh check the auto oil level...only other thing i can think off is the coolent being low that the coolent temperature sensor would be reading wrong causeing the tourque converter not to lock up as the car has to be warm before it locks up....i think teh vn/vp is like that i know the vr/vs is |

| Are you saying that it wont go from 3rd - 4th?? Fourth is your overdrive gear. |
What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| The cable that goes from the throttle body down to the transmission make sure that's in working order first |

| 4th is overdrive when the revs drop at 80-100 thats the torque converter clutch locking up obviously its not locking for some reason could be the trans temp switch or engine temp switch or the tcc itself or the ecu or the kickdown needs adjusting |

| you got an aldl cable and a laptop.the ecu temp sensor could be reading the wrong temp and messing with idle and TCC lockup. |

| only VR/VS V8 manual will fit and work auto ecu's are no good.you need to swap your memcal into the ecu as well or it wont run with the security active in the tune on the vr/vs memcal |

| yes v6 too but only manual ecus's though and the tune in the vr ecu doesnt suit the vn engine very well due to different compression ratio and different cams and headflow and with the security in the bin it wont run without turning it off in the bin file and reburning a new chip |

| yip very different tune tend to be down on power and use more fuel when running a vr tune in vn-vp same when people convert to vr engine in there vn-vp's and run the same vn ecu and tune just not optimum for the engine. |
