In any case it's not entirely clear that OP's problem is actually an internal gearbox issue, it sounds more likely to be electrical.

True, but my advise about Flushing is related to the 130000Miles on the meter, and if you are lucky the problem dissapear, and yes if you drain the pan 15 times you get the old oil out, but a expensive solution.

Don't flush it. That won't help and can even cause damage. The correct way to service the transmission is to drop the pan, drain the fluid out, replace the filter assembly and refill with the correct fluid. If you have no history and the fluid looks black then you definitely want to do this at some point if you plan on keeping the car, ideally as soon as possible once you've made sure that whatever the current issues are aren't terminal.

If it drives ok it may just be electrical glitches as Colin suggested. I'd start with the battery, if that checks out, take it to a Lexus specialist and ask them to diagnose it. Or perhaps an auto electrician since the issues point more towards electrical if the transmission is shifting ok.

Drop the pan and change 1 litre? i flushed mine, got a better gearbox, but i cant promise that it vil cure his gearbox, but my car gear a lot faster now. My car was flushed vith the Toyota WS Fluid only, not the cleaning fluid normaly used first in the Flushing. Have 5000km on the meter after Flushing, no isues.

Hi Steve,

How can I tell if I have the Master Key? It does have the 3 buttons on it, never realised it did the glovebox though!

I got 2 identical keys.

Get new oil, flush out.

Is this easily accessible ? If it's the cabin ambient sensor ? Any advise would be appreciated
Thx Paul

It was easy on my old is200, probably more or less the same on the 250, same location. But i dont think there was a tube on the Is200, only electrick conection.

Sheck the temp sensor, maybe the cable is disconected. Happened to me.

Asking price?

Well my car is now in Stockport Lexus for a MOT and intermediate service but with the addition of trans oil change. When I booked the car in and chatted with the guy he had to ask someone. He came back with a price of £20. Yes 20 quid. I said surely not but I booked it. So this evening when at Stockport the guy behind the screen told me its a sealed for life box, as written on the job sheet. I stated its not and that Aisin recommended 50k oil changes. He phoned a tech guy who came back with yes we can do it. I.5hrs and £30 for the oil. I questioned the price of the oil and he confirmed 30 quid for 5 litres. £216 all in to do the oil change.  Well I'll see tomorrow what was done.

I'm in a UX250h as a loan car. 2.0 litre tho. By eck it shifts lol

You only change 1/5 of the oil, not much help.

Eh up Alf what lingo is that?

Sorry, the tread starter is Norwegian and i am an Norwegian, so i used Norwegian language. 

Kjøpte en 250 med alt tenkelig utstyr 2006 modell, 250000km på meteret for 83000kr i Mai i fjor, veldig fin for alderen og stort sett bare langkjøring. Men får du biler med 100000km til 150000km så ville jeg vurderert priser opp til 150000kr. Kommer helt ann på tilstand. Diesel ville jeg holt meg langt unna.

The picture when they are switched off looks like they are reflective red??

They are not, i have them, no reflective red. Easy to bay some reflective sticker if needed.

Do these act as reflector when  not illuminated?

Rear reflectors are required and checked during the MoT test

No.

How much labor time to change the dif?

Why using mony to romove this Tow bar, you never know when you need it. In my car there is a cutout in the bumper aswell.

I'd want to know exactly how they're doing the flush, from what I've heard the usual process is they attach to the cooler lines and cycle the fluid in and out through that with the transmission running. A lot of the clean fluid going in comes straight back out the other side, so you end up replacing far less fluid than a normal drain/fill would, but I'd be interested to know if they're doing something different. I'd also want to know how they could ensure that there wasn't any fluid of another type left in the machine before the process was started.

They plug to lines to the gearbox.

The saga goes on.

Basically even within this forum there are loads of people saying, don't change, change, never flush, I flushed and it was great...

So I have spoken to Devon Gearbox Centre who come well reviewed and spoken to the owner a few times. He recommends a flush and complete oil change of the transmission. He said issues can occur when using cheap machines to flush with but they use a £3000 machine rather than a £300 one (am I being incredibly gullible?!). He says they have flushed thousands of "sealed" transmissions with no issue (although admits not done a lot of Lexus transmissions).  He is going to use a genuine lexus filter and the recommended fluid.

Not entirely sure why I am posting this as I think I am just going to go for it. To put my mind at ease I would love to hear from people that have had transmissions flushed and it has been fine! For reference the car is a IS250 from 2008 with 86,000 miles on it. It has no issues with shifting at the moment at all. I think I will be fine... but I am nervous!

I will certainly report back with the results... jeeezz

P.S. please don't advise unless based on actual experience! The internet is full of that!

Have done it, the gearbox is much faster in  down Gearing, did the flush because off high milage, no problem with gearbox. Before i could drive uphill in low speed in a higher gear and the car start to ratle, no this is not posible since the gearbox will gear down and rise the rpm, wery recomended.

1 litre from the sump.

I wouldn't polish the multimedia screen at all. It's a digitizer. Some digitizers also have an anti-glare coating that would get ruined. Few years ago I changed my digitizer anyway as ribbon cable on the digitizers eventually develop fractures that causes the digitizer to fail and the touch response to stop working. I replaced my digitizer with a replacement from hong kong for very cheap and my screen condition is very good. No scratches on my screen: Pic of the digitzer i replaced below:

I have a digitizer screen to replace vhen i ned it, but i vait until the original brake dovn. No problem to keep the scren as it is, only plenty of touching that have made some Spots litle ligter black , no scratch, only hoped for some smart solution.

I forgot to add that I also took the oppertunity to change the shift position bulb to a blue LED. But when changing that bulb you need to wrap or black out underneath the bulb so that you reduce the light from bleeding. I also polished that perspex shift position trim. It's plastic so scratches up very easily. Mine was in a nasty condition so a polish has made it like new again. A few pics of that below:

 

  

Have you tried. Polish the multimedia screen? Have some marks where the fingers have touched many times, lower right corner is Worst.

Wery Nice. Are you doing this bay yourself?

In Norway IT cost the doble. You are lucky in the UK.

Acording a repair manager in Lexus Norway a Flushing vil clean the filter about 80 %.

I personally avoid transmission flushes. If transmission flushes are done at shorter intervals from new then yes it can prolong the life of the transmission. But the reality is that most people will follow the "manufacturers" sealed for life claims and not touch their transmission until some problems arise and then all of a sudden they start looking at transmission flush. A transmission that has not been serviced and starts to develop issues which then goes on to having a flush is at very high risk of failure after the flush. The idea of a flush is to completely clean out the transmission, but this dislodges a lot of buildup materials and in worn transmissions these build-up materials are actually helping to continue to just go on. The minute it is flushed some of those materials will end up in places it shouldn't too. One is probably better of adding some friction modifier to a worn transmission just to keep it going that little bit longer. I personally do a trickle fluid change every 20k/2years and a sump drop and filter change every 60k. Trickle change is simple, just drain, re-fill then run up to temperature. Then I repeat the step a few times and that dilutes the old fluid with some new fluid giving it a better chance.

Ofcourse this is my personal opinion and based on my personal experience of owning my car for 13 years and covering almost 200k miles on it. 

My flushing was done bay only using the atf and not the cleaning stuff that is there vith normal flushing, advised bay Lexus to avoid that partikkels vill end up in bad places, have 4000km after the Flushing and so far so good.
