Thread: Tranfer case stuck in Low range

Range Rover Sport 2007 TDV6. The transfer case was recently rebuilt and the gearbox serviced with new filter, LifeGuard 6 fluid is used. There have been issues since then with the transfer cse getting stuck in low range. The IID Gap tool has the general list of errors that are on other vehilces on the internet, eg. Terrain Response U416-94, U403-94, U421-94 and Transfer Case P0915-00. The Gap tool will clear the faults but they come staright back, this is the same as others outr there.

The mechanic shop managed to get the vehicle out of low range but the Terrain Response errors persisted. I drove it around the block a bit cleared faults, turned vehicle off and on (not in that order but you get the gist) and then the alerts went away and the car was alert free. The transfer motor was tested on Friday night via selecting Low and High (gearbox in Neutral as required) after 2 cycles it decided to throw the error again, so it's now back to the alerts but at least it's in the shed this time.

All of the electrical conctors on the transfer case have been cleaned, the transfer case motor was heard runnning during the testing, the transfer solenoid was heard clunking doing it's job, but alerts will not clear.

After searching the internet for a few hours, a solution pointed to possible gearbox adjustment needed. The Gap tool was plugged in and the gearbox transmission gear reading checked. When the car is in Neutral the gearbox reports it being in 2nd gear. All manual gears are selectable and the correct gear shows on the dash, it's just Neutral that is 'wrong'. The car doesn't move in Neutral so it's not in gear

Could this be why the transfercase fault appears, it cannot do anything if the gearbox reports 2nd gear when it needs neutral ???? Is there a senor in the gearbox that needs to be/can be adjusted to calibrate the ECUs and the mechanical position ?? Are there readings on the Gap tool that would confirm if

Or is it simply the transfe rcase motor has failed and needs to be replaced? I do not want to have to open up the gearbox again for 50K Kms.

Any help is greatly appreciated

The issue continues, it has since been checked by a European car mechaninc with thier equipment to no avail. The car had been put into high range manually and driven to their workshop. They could find no faults. While there the vehicle was put into low range to demonstate the problem (it's a short drive home). All of the faults appeared, the car was left running during the change. They could not clear the faults or calibrate the tranfer case motor. The car has since returned to the gerbox mechanic who has removed it and checked all operation on the bench. They suspected the solenoid, measured the resisitence and came up with 0.8ohms. Searching the internete suggests this is not right but there's nothing definitive.

Does anyone know the resisitence of a new solenoid??? I've got workshop manuals but havent found it.


Searching the internet is not delivering much in the way of a solution. This vehicle only had an oil leak, the transfer case and range change was working perfectly just two week prior. We have a trip coming up in less than a month......
