2001 Range Rover 4.6 Vogue Gearbox Fault please help
Discussion
Hi, Driving home the other day and gearbox fault comes up on message center. As i pull away have to rev a lot more to get going, to build up speed, feels like its stuck in 3rd or 4th gear. The odometer does not display what gear i am in anymore as well and the sport mode is not working. I got it home and when parking it cluncked a bit when put in reverse, so i turned the engine off and looked underneath the car and there was water leaking for about 10-15 mins. Its definitely water and not coolant, coming from the area of where the gearbox is. I did have the aircon on, so not sure if the drains are there, but i did have some water in the passenger footwell about a month ago. The gear selector lights work and are not flashing and i have put a new bosch s4 silver battery on. If the aircon drains are blocked can the water be leaking elsewhere ie footwell and causing the problem. Can anyone tell me where the gearbox ECU is and can water get into this? Any advice would be much appreciated.
I have had a look at the ECU under the seat and unplugged and put back together and looks clean and dry, but obviously it could still be dead. I used contact cleaner inside the 2 connectors under the expansion tank and checked fuses. Can i still drive the car to the garage or can this cause more damage? Also if the display is not showing what gear i am in, does this mean it is definitely electronic prob, not the gearbox gone?
I am in enfield middlesex. I need to get it looked at, but dont want to cause any damage to the gearbox, by driving to a garage. I might have a look at the XYZ switch, that was mentioned, as when the gearbox fault come up, i stopped and looked under the car and there was a lot of water coming out of the ac drains i presume and i haven't seen this happen before. Maybe the water can be going in the XYZ switch and causing the fault.
Someone said that the ac drains can drip water into the xyz switch if the breather tube is not attached. when gearbox fault came up, i stopped and looked under car and there was water coming out for 15 mins, never noticed this before and i would of thought it wouldn't normally come out for this amount of time. Also, would the gear selection on the display dissapear if the xyz switch was faulty?
thanks for the pics. I meant there is a breather tube on the xyz swtch and if it has come off water can get inside. Its going for diagnostics on friday. Since the gearbox fault came up, i have put a new battery on, checked alternator ok and cleaned the two connectors under the expansion tank, as was told this can cause problems. Also checked fuses. Is it possible that i have cured the problem, but need the gearbox fault cleared, or would it of cleared on its self.
went to the garage today and there diagnostic tool cant get into the system, but it has come out of limp mode. They checked gear selector switch and clean and dry. Drove home and went back into limp mode, so i thought of trying all elec switches in the car and when i turned the headlights on, left hand low dip beam bulb failed, came up on the message centre. I checked the lights and the bulb is working and not failed, also when i put the lights on the message display goes dim and when i turn lights off, it is bright again. The car had also come out of limp mode as the gear selection was showing on the message centre again. Does anyone know if this is connected to the gearbox fault coming up on the mc.
Sorry have been away the last week, so took the rangie for a drive, started with no fault coming up, but after about 15 mins gearbox fault comes up and into limp mode. I got home turned it off then restarted and fault gone, so last few journeys it happens 15 mins from start, then turn off, restart and ok again. Its very consistant 15 mins from start, can this be when the ac drains start dripping possibly on to xyz switch, or transmission oil getting hot, possibly oil cooler not working, any ideas please. thanks
Thanks for your input, yes probably take it for land rover specific diagnostics this weekend. I did notice that the clamps on the battery terminals was not really tight,i could move the clamp if pushed quite hard, so have tightened them. Need to take it for a drive and check it wasn't that. Could this cause the problem, or would they have to be really loose?
update, took it to lr specific diagnostics and no gearbox fault codes logged. Drove home and when i turned the wipers on the gearbox fault come up again, the exact time i turned them on. Is it possible that my alternator has an intermittent fault when hot. The car is ok for first 15mins, so im thinking that when the alternator gets hot is when it fails? The only thing is, sometimes when i start from cold, the gearbox fault comes u[p straight away, when alternator is cold. Please can someone advise me on intermittent alternator fault and any tests i can do. thanks
took it to a land rover specialist with land rover specific tool t4 and no communication. I think there is power from the plug but no comms and they dont want to get involved with a p38, the same as 2 other specialists i have phoned. The fluid levels are ok. does anyone know how many sensors there are for the gearbox, what they are and whereabouts? Im driving around short journeys in and out of limp mode and its been over a month now. thanks
