The manufacturer of the gearbox specifies that the oil is changed every 50,000 miles, any time the g/box is overheated the useful life of the oil is halved too as ATF breaks down much faster if it heats beyond it's tolerance.

I've heard this can be due to a partially blocked radiator as the bottom few tubes cool the gearbox or something?, quite a common issue on them, definatly change the gearbox oil and worst scenario might be a new rad too. |

Scorchio did you change the rad too?, I have and the only thing I can think of now is either an airlock or it's got to be an iffy gearbox sensor.

Nappler - optimistically thought the oil change would fix it ... so no - haven't done anything else as yet ...

I had the same symptoms, changed the oil and the filter, still had the problem. Then changed the radiator and the heat exchanger, problem went away. Filter was black, radiator was blocked on the bottom few tubes.

It is possible to flush the box, it involves taking a hose off somewhere and letting it pump the new oil in and the old oil out.

I'm sitting in a petrol station at the moment after the car has done it again, guess I must have a blocked oil cooler, it's all I can think of now, since I've owned the car it's been off the road more than on!, and I thought a TVR was unreliable. |

Problems caused by poor maintenance (by previous owner) can't really be blamed on reliability... I'm just having a flick around online to see if there is any way to read the emperature of the box without T4 and I can't find anything. I know my OBDC software doesn't read g'box codes or temps. ![]() |

Was in the mechanics earlier and box temp was about 113-114 after the car was left idling in park. Got a new oil cooler ordered and will be getting fitted on wednesday, the only things left it can be are the cooler or the sensor itself. I know it's not really the cars fault, just getting a bit frustrated with it at this point!. |

Rad fitting shouldn't take more than an hour, I paid £167 for a new rad from Autopost. |

The oil cooler was blocked, the car sat in traffic for 30 mins yesterday and was fine, it seems the problem has been fixed.
