Hi guys, similar threads have been posted but not exactly the problem I’m having.
My 2008 Range Rover l322 HSE model has recently started playing up shifting gear from 3rd gear onwards. It has been happening for 3 months now. Once it gets as far as third it won’t shift into fourth until hitting around 4000rpm or above, and the same then into 5th gear. Putting it into manual mode it drives fine and has no problem going through gears and staying in gear, it has no problem downshifting itself also. Mechanic replaced the transmission oils and possibly gearbox oils etc which I guess was the first and cheapest possible fix, but to no avail. What do I do next? Could it be a radiator problem? He couldn’t see any visible signs as to why it’s happening and no codes / dash errors etc. any help kindly appreciated as I will be selling the car and want it in full working order for the next owner!

Kind regards,
Darren
 
Any harsh shifts?

Flaring between gearchanges?

What oil did your mechanic use in the gearbox?

What miles are on her?


@blue beasty would be be so kind as to move this to the range rover section please..

Hi Henry,

Thanks for the response.

No harsh shifting in manual mode, works perfectly through all gears, and when driving in automatic it seems to hit 3rd gear no problem and anything after that it won’t upshift until serious high Revs. Not sure which oil he used, I have read on few different forums it could be to do with the trans cooler / radiator - could anybody confirm this?

car has 210,000kms done.
 
Is this problem temp related?

Does she do this after a few minutes of driving or is it apparent from the get go?
 
Did your mechanic do a stall test on the box?
With everything up to temp press foot brake hard down and press accelerator to the floor watching at what speed the revs stop rising. Do it quickly and leave to cool between tests. Dont hold accelerator down for more than 2 or 3 secs.
The revs should rise no more than 2500-2750 (there may be a figure in the book). If higher then the clutch plates are slipping if lower then TC issue.
Your change speed may be clutch slip and higher revs at stall point.
 
Hi all,

I am just checking back in to update everybody and possibly provide some information to anybody who might experience this problem. I had gotten a flat tyre a few months ago, the gearbox problem started happening shortly after that but I didn’t put 2 and 2 together. The spare wheel put on was ever so slightly smaller than the 3 others on the car. It was the front passenger side wheel. It was a 255/50 R19 whilst the rest were all 255/55 R19. I came across a thresd somewhere where somebody had a similar problem to mine where the car would not shift higher than 3rd gear. Somebody had recommended to check all tyres and make sure they were the same. Turns out the imbalance in tyres caused the Range Rover to enable a safety feature as such referred to as ‘cornering’ mode? After switching back to the original wheel and all 4 same tyres I am happy to report the issue has went away and the car is shifting gears beautifully again. Whilst 2 seperate mechanics never picked up on this and recommended I replace the gearbox and all sorts. So that has saved me a pretty penny!

Thanks for coming back with your findings. While all 4 wheels and tyres should be the same on a 4 x 4, overcomplicated electronics do not help.:rolleyes:
 
Good result:) so one wheel sensor was reading slightly different to the others and it decided to have a hissy fit:D
lesson learned there.

Darren, did your situation resolve itself immediately or over time? As in, time for the trans to learn all tires were now the same size and ok to shift properly?
