I think it was the pipe going into the oil cooler from the gearbox. They replaced the oil cooler in 2017 and I have had to replace it again this month. I believe that is a weak point. Yes definitely keep an eye out for it. It looks a lot like coolant when it drips (red in colour)

Just to add the ISF gearbox itself has no issues. The reason my gearbox got damaged was due to it dropping all its oil on the motorway and it went into limp mode and I was 'making progress' at the time. Mine leaked due to a pipe leaking near the oil cooler

Failed transmission was mine. Lexus replaced the gearbox and a few other bits and bobs. I have recently had to replace the gearbox oil cooler again as it started to leak. The op's issue maybe oil pressure in gearbox. The symptoms sound just like I had.

That's the total bill which includes new gearbox, new torque converter, new exhaust piece that has the lambda sensor, new lambda sensor and all the labour charge. Next time I am there I will see if I can get the full breakdown of each part but I think the gearbox on it's own is around £8500.

Collected the car earlier today. Drives perfect now. The total bill came to £18k in the end.

Yes. Glad I argued my case to them.

Thanks pal. Just glad it is all sorted now.

UPDATE: Right guys, major update due. So Lexus did eventually agree to repair the oil cooler and pipes etc. However since the repair the gearbox has not been functioning correctly. It would not go into gears easily. It would labour when shifting up and you had to press down on the accelerator for it to pop into gear. I have been driving it in manual mode for the last 12 months!! The car has been taken into Lexus Leeds on a number of occasions to try and solve the issue. However the problem persisted and Lexus UK have agreed to replace the gearbox! Great news! I pick the car up on Monday. They have also replaced the manifold. The bill in total is over £15k I believe. Glad I had warranty. Its not been an easy process but we have got there in the end!

thanks for all your support guys, much appreciated. At least I know other people also agree with me that Lexus are being extremely harsh with the way they are treating me. I have been on Twitter to vent my anger and Lexus have contacted me straight away and asked for my registration and claim number and stated they will get someone from customer relations to contact me. I have also emailed Paul Van Der Burgh and Richard Balshaw raising my concerns.

The thing is I am due to fly out tomorrow afternoon and will be out of the country until the end of the month. Trust it to happen now! just my luck! I will be raising a complaint first thing in the morning with Customer Relations. I do believe they are just looking for an excuse not to pay.

By the way the last service was just an oil and filter change

Right guys, Lexus UK have rejected the claim on the warranty. they are saying as my last service was not done at 10k but at 12k, they refuse to cover any warranty work. I stated to the dealer that they have been servicing my car since 2014 and it was only slightly late on this occasion. However Lexus Bradford refuse to budge and have just redirected me to the Warranty department. I tried to call them but they are closed. I stated to the dealers that there was nothing wrong with the car when I had it last serviced by them a few weeks ago so therefore I do not feel it is fair that Lexus are trying to get out of paying for the repair. I have been told at this stage it is the oil cooler and some other part (to be honest I was not listening properly by this stage as I was fuming to say the least) The cost of repair is £900. Lexus Bradford should have warned me at the time I got my car serviced that it may affect the warranty as I have gone over 2k in miles and I could have then purchased the warranty elsewhere! I have not had a good experience with Lexus over the last few days and this has just really wound me up!!!

I will speak to them on Monday, to be fair I don't really need one as I am abroad from Tuesday for the rest of the month. I will be more than happy if they arrange airport transfers as I was going to park the ISF at the airport, so I will request this instead of a car. In fact that reminds me I need to cancel the the parking.

That has crossed my mind, however, i believe there was plenty of oil within the box as it left a large puddle on the flat bed truck. One thing I did question is why does it not have a sensor in the box to warn you if the oil level decreases? However because it went into limp mode and I stopped straight away the recovery guy said it may have protected itself by going into limp mode as soon as it detected oil level decreasing. Guess all I can do now is sit and wait for Monday to see what Lexus say

I am hoping it does not need a new gearbox, as that will have to be ordered from Japan. I very much doubt they would put that on a plane given the costs so therefore will be shipped. Looking at 6 weeks turnaround at minimum I presume.
