Hello! When the problem occurs Try backing up...If there is not a problem then Transmission clutch "A" is at fault...A known vulnerable point is the snap ring that retains the A clutch pack...Increasing fluid temp. causes leakage and pressure to drop...Dumping the clutch and putting you in neutral...

Major rebuild...

Range rover 2006 sport diesel auto trans not shifting in D mode only shift in triptonic I change trans control module but its showing u3000 code now what to do?

the transmission control module has to be programmed to the vehicle using suitable diagnostic equipment. the code you have got i suspect is telling you that, all the modules on modern vehicles communicate with each other via. the can and scp networks to work correctly. if that has not been done, that is more than likely the problem, or the road speed signal may be missing but i suspect you would have other fault codes logged. hope this helps. ps. i worked for a jaguar franchise before i retired, they use the same systems, same company.

How i fix the p0730 and p0735 in range rover 2006

Possible causes of OBD code P0730
- Low transmission fluid level - Dirty transmission fluid - Shift solenoids - Shift solenoids harness or connectors - Transmission mechanical problems - Transmission hydraulic control circuit The Error code is generally activated on detection of the following conditions: The TCM has detected that the transmission is trying to mechanically shift to a lower gear than intended

Possible causes of OBD code P0735
- Low transmission fluid level - Dirty transmission fluid - Shift solenoids - Transmission mechanical problems - Transmission hydraulic control circuit The Error code is generally activated on detection of the following conditions: P0735 is detected when A/T cannot be shifted to the 5th gear position even if electrical circuit is good.

Range rove 2004 is in engine failsafe mode is not starting?

You need an owners manual or access to factory
manuals to find out how many fail safes your vehicle has

Example: Electronic Throttle Control
Engine Over Temp
Transmission Failsafe
Misfire Fail safe to protect converter

Once you have checked for codes which I assume you have
done long ago,you use them as well as trouble charts to
diagnose things

Hi, My 02 Range Rover has a warnig light showing trans safe mode. I put it into low range with no problem drove for a couple of miles and tried to put it back into high, with no joy. It is driving ok and...

these rovers are made like a big computer...if theres is anything wrong with the transmission it will put itself into "safe mode" so it wont rev high and basically you cant go very fast. so you could have a stripped gear, low fluid, or even the gears could be too close or too far apart.

Have a 2004 range rover with p122b code output speed sensor. Replaced sensor and checked wiring in transmission and going to control unit. Did a transmission service, flush and filter. You can drive all...

This might sound odd, but it could be the gearbox output shaft bearing. If the transmission sounds noisier than it did, this could be the issue. Only way to check is to take off the transfer box. Not a major job, but takes a while. Some good fault code readers will read transmission codes, and allow you to see in real time what the sensor is doing - if the sensor suddenly loses signal, then it is very likely to be the a bearing (output shaft bearing most likely) that is at fault, causing the sensor ring to move too far from the sensor. Best guess, but could be other things, so don't go taking that transfer box off without getting a road test with a good fault code reader on it - or find someone with a portable oscilloscope and put that across the sensor - you should be able to see nice square wave pulses - if they get bigger and smaller (variable amplitude), that's your problem. If not, the fault lies elsewhere.
