    Could be a variety of things sticky valve block, govenor clogged up with debris. Take a look at Ashcroft transmissions they have a FAQ area i think. Interior lights, have you tried pushing the centre switch on front interior light for more than five seconds, dash message will say interior light active. Or at least mine does, you can switch them off the same way, if someone has inadvetantly done that it maybe your problem.

    Have similar issue with my box and have been advised to remove and clean the governor (although my local garage said they've done this a few times and it didn't improve things), I'll do this when I get chance and see what happens.

    I changed my filter and oil but it didn't get any better, in fact if you look at Ashcroft website FAQ they are now saying that the oil can dislodge debris and make the problem worse.

    I'm going to do the governor and if that doesn't work I'll just live with it until I need a new box

    Hi, I have a strange problem with my automatic gearbox on a P38 4.0 liter.
    It run only in "R" position, when I am putting it into "D", "3", "2", "1" it is not happening anyting... I have to mention that the car is 1999 model.
    Any ideas for fixing this problem?

    If the gearbox is "overhead" it must mean the car is on it's roof. This is usually caused by going round corners too fast:behindsofa::hysterically_laughi:hysterically_laughi

    I'm afraid I can't quite make sense of what you're saying.

    Repeating it numerous times isn't really helping either.

    I think you're saying that your gearbox is overheating? But I don't understand the rest of it.

    Consider low range would be better idea than high drive 1 and 2.

    the oil is overheating in if the sensor can be trusted
    .
    if the sensor is replaced and it still indicates overheating then a custom oil cooler required and electric fan.

    i think he is saying that the g/box overheats when he goes up the mountain road in 1st,2nd or just drive.but it only overheats in the summer.he needs an g/box oil cooler,or his one on the car needs cleaning.
