Losing Auto Gearbox Oil after power transfer case (PTU) Fit

Hi everybody!

I've been an owner of a 2007 Freelander 2 for a year now. This forum has helped me tremendously to tackle a lot of issues i've come across in the past year.
Unfortunately I haven't found a topic with a similar issue as I have now:

I got a new PTU fitted, since I had a grinding noise coming from the front during acceleration and driving uphill. The new PTU totally fixed this problem but it has created a new problem which I can't explain..

I'm losing ATF oil on the right side of the PTU where the front right drive shaft is leaving the PTU. It is not the PTU oil since it has a cherry red color.
I've levelled the gearbox oil as explained in this topic: https://www.freel2.com/forum/topic28619.html

Does somebody have a clue what the cause of this leakage can be?
The gearbox is still shifting fine and I don't notice any stuttering.
Thanks in advance for any possible solutions!

2009 Freelander 2 TD4 SE Manual Rimini Red

I'd guess that the gearbox output seal has been damaged whilst the PTU was being replaced. This is allowing PS fluid to escape from the gearbox, and find its way out the driveshaft seal.
It's an odd one, as fluid from the gearbox would normally escape from the weep hole in the PTU connection section with the gearbox. Hyundai Ioniq 5 Ultimate. The family car.

I supplied the garage with the PTU (https://www.lrparts.net/lr066503-front-differential-power-transfer-unit-ptu-for-freelander-2-and-evoque-mk-1-for-2-2-diesel-and-3-2-petrol.html) as they are not widely available here in Switzerland.
They said that they have done similar jobs before and accepted it but they didn't gave any guarantee on the labor or parts.
I went back to them and they can't pinpoint the problem. For them to diagnose it properly the'll have to disassemble the PTU again which will cost me quite a lot..
i hope i can find out if the problem lies with the TPU and is not a bearing or something in the gearbox....

If I was in your shoes I would call Austen at Bell Engineering. He is very friendly and helpful and will no doubt have an answer for you.

Looks to me from the photos that you just need to renew the seal. I would try a better garage

Thanks for your answer, do you mean A or D? The garage also changed the gearbox sleeve (LR002746)

Thanks, I've heard a lot of good things of him around this forum. I originally also wanted to buy the PTU from them. unfortunately they don't ship abroad.

The strange thing for me is that the oil has to push through multiple seals as there is a seal on the left and right side of the PTU where the drive shaft is going through.
