Hi guys

i was driving earlier and stopped at red light everything was ok then went to accelerate and this massive shudder happened like as if car kept getting stuck then go stuck then go quickly could hear the loud noise and the whole shook with it as well as steering wheel.

Lasted only about 3-4 seconds then disappeared and didn't happen again.

I'm scared... Is my transmission showing signs of its near death?!

:'(

I'm thinking hopefuly it's the inner cv joint/drive shaft. As it is leaking grease. That might also explain the clunk I hear at acceleration ...

is this plausible

Aurions can be pretty aggressive with wheel hop, especially when the traction control intervenes as well.

It definitely won't help the matter.

Thanks Trent,

Just another quick question...

When i floor the car it doesn't always get a big kick of power, sometimes just accelerates at a steady pace, car still speeds up just not with the power that it should...this is about 50/50 sometimes has power sometimes doesn't its weird...

is it the transmission not selecting proper gear or some engine issues, lifters etc..?

Anyone else experience this.

Sorry Trent but I disagree, my prodigy is no TRD but when you put your foot down it gets up and boogies, regardless of if its in drive or sport.

there has been a couple of times that it has had a less aggressive acceleration but it's not like it's driving miss daisy.

i have also found that my floor mats (stock Toyota and R.M.Williams deep dish) occasionally stop the peddle from going all the way to the floor.

I am not basing this my car only. I worked for a while with some fleet vehicles, that had almost the exact same feel to them.

It's almost like: press accelerator, pause, wait for the trans to decide on a gear...power.

I have a prodigy and it happens at times, unusual, generally responsive if I want to floor ir from a stoplight but at times if I've slowed to a giveway and then go its slugish. Could it be motion related in a traction control sense?

Yeah it's mostly slugish when i floor it while still rolling, from a stop its usaully aggressive but sometimes if I slam the accelerator too quick (from a stop) my front tyres loose traction and the car shudders real bad for a couple seconds. 

Does this happen to anyone else? should it be loosing traction so easily ?

It's just the power of the engine getting passed to the wheels a lot faster than the traction control can kick in. Nothing to be surprised about.
The general response of the transmission can also be from what it's "learned" to do based on your driving style, apparently it's made to accommodate the driver. You can get the learning reset at a dealership, alternatively I haven't tried it myself but you could see if draining the power resets it too (disconnect battery,hold foot on brake to get the lights to drain any remaining charge from the system).

 

Now, regarding the original problem, I've started to have a similar thing pop up in mine. Only happened a handful of times, but pretty much come up to a roundabout, almost stopping whilst checking for traffic from the right, then release brake and go to accelerate and feel a crazy big thwack from the gearbox, not sure how to describe it, kinda like it got stuck changing between gears and when it finally moved there was a large amount of tension that was released in an instant, kinda like tightening up a spring then letting it go.
Hell worrying, but doesn't feel like there's been any issue to the general operation of the gearbox.

Blocked inline filter is the cause of  transmission shudder in 2001 Honda Accords. The transmission filter can get blocked after about 80,000Kms. Only real solution is to replace the transmission filter which involved removal from the vehicle and dismantling the transmission. Another sealed for life engineering decision that did not stand the test of time in the real world. Those Honda transmissions did not have a pan you could unbolt to access the filter but it did have a dipstick.

I have replaced the transmission filter in my 2006 Aurion which had done 165,000Kms. There is one bolt which is difficult to access due to a chassis cross member and then making sure the fluid level is correct else more problems.

If you knew a reputable transmission shop that is experienced in servicing the U660E transmissions, then strongly consider getting them to replace the transmission filter.

Also check the engine and transmission mounts to make sure they are are not broken or damaged. Quick check is to rev your motor and the engine should not move or very slight movement.

I have used Sikaflex to repair and reinforce the rubber engine mounts. Yet to do that on my Aurion but it is on the maintenance to do/check list.

      Auto door locking on new 2024 C-HR?

      Thanks Martin. I thought that may have been the case. However, it seems an anomaly with so much tech on board. My wife always looks for this feature after an ugly incident while stopped at a traffic light some years ago. As you said ...perhaps an OTA update? One other thing if you don't mind me asking. What is the build date on your vehicle? The C-HR's that appeared at my local dealer in the last fortnight all have an October or November 23 build date. Thanks, Peter

      Transmission U660e

      Not every Estima is fitted with the 2GR-FE and U660e drivetrain. This is where you have to take care that information on the internet is applicable to your specific vehicle.

      Auto door locking on new 2024 C-HR?

      Hi I was very lucky to receive one of the first new models last month. My Koba is amazing- as have all of my previous Toyotas. However in answer to your question it does not automatically lock the doors when you engage Drive or when you reach a preset speed. I am very disappointed that with all of the electronic devices and safety features and the approximately 20% increase in price over the last model that Toyota Australia has left a very important safety feature out of the vehicle. We see cars being carjacked almost nightly on the news. My knowledge of technology in this sector is limited but surely it is only an update of the operating systems to fix this. The new model is a beautiful car- your wife should still buy one.

      is it possible to import US model Sienna to Australia?

      I rent a 2023 model in US just few days ago it’s beauty and real good on fuel much nicer to drive compare to Honda Odyssey which I own one 2022 model make me wonder why Toyota AUS won’t bring the Sienna hybrid to Australia instead we get bulky ugly looking Granvia with diesel engine 🤔🤔!!

      How to delete bluetooth device?

      I have a Yaris and had a similar issue. I just submitted a similar query to GPT. The response was to go into settings, view paired devices, select the device to remove, and confirm the removal. It helped me; I couldn't find the answer on the internet, but I found it there.

      Transmission U660e

      @campbeam much appreciated, very interesting, it’s got me buggered as on the Toyota Estima groups everyone is quoting 1.6 litres cold for a drain and drop, now, these run the exact same drivetrain as the Aurion 2GR-FE and U660E combo, so in theory all figures should line up, I’m hedging my bets on your maths and techniques though, you seem well versed…. thanks again

      Auto door locking on new 2024 C-HR?

      My wife is looking at purchasing a new 2024 C-HR Hybrid. Does anyone with one of these know whether the doors lock automatically when driving off? Her 2018 C-HR doesn't do this which is annoying as my 11 year old Kia Sportage does.
