    Sorry to revive an old thread, wish I’d checked here before I took my car back to the dealer. Brief(ish) run-down: bought the car in December 2017, returned it to Frankston Toyota (Vic) 3 times for repair of a “flare” in transmission at 55kph every morning and not dropping into 6th at freeway speed. Each time I got “couldn’t replicate fault” and “reset ECU was performed” was all the info I got. Eventually recorded the problem on video for 7 days straight and sent to Frankston Toyota and they agreed to send a tech to my house to see it occur.

    Tech bought a diagnostic computer and recorded the drive, told me it wasn’t a “flare” but the car changing from 4th to 5th then back to 4th really quickly. He stated clearly that it shouldn’t happen.

    Took 4 more weeks to get it booked-in, been driving a loan car for 2 and a half weeks while my car was sent to Pakenham Toyota. Got one update in that time “still determining the issue, haven’t finished diagnosing it”.

    Now today I get told that it’s ready to be picked-up. I asked to see what was done and received a service tax invoice from Pakenham Toyota “reset ECU to reset/relearn any data inputs...” there is a comment on the tax invoice about “our experience with these vehicles and transmissions suggests that some flaring is of shift up is characteristical (sic) and other inputs such as load, driver input and temperature all play a part in vehicle performance. No apparent faults found”.....in 2 and a half weeks. Does this sound like the same problem everyone else is experiencing? Wouldn’t hunting for gears damage the transmission? Why would this show on the tech computer and happen everyday to me but not be replicated in test? Any advice gratefully received. I’ve refused to pick the car up and I’ve kept the loan car, I’ll contact Toyota Australia tomorrow, but I’m worried I’ve bought a lemon.

        i cant add much , but can say that mine does not do that "flare" thing which does not sound normal to me. Not dropping into 6th is normal for these gearboxes , its been reported many times and more a function of keeping the DPF system happy. Owners have learnt to live with that one , at speeds above 110+ it does drop into 6th properly.

        ask them if you can borrow their demo Tuna , and take it for a drive from home along the same section of road and see if it does the same thing as your car?

          I get the 'flaring' type of issue that you're explaining at times too. It happens for me mostly when I'm coasting with a particular amount of throttle input say around a roundabout or a corner. The gearbox definitely seems to be hunting for the correct gear at times. It feels exactly like it shifts up sooner than it should??

            Picked the car up today, yet to see if it still does the same thing when cold, but nothing was done to it that hadn’t already been tried, so I’m not holding out much hope. However the dealer has agreed to get a tech from Toyota Australia to come to my house and get me to demonstrate the problem. I assume I’ll find out if this is normal or a quirk rather than a serious problem.

              Hi Woo78, did the issue come back?

              Ours has always been better for a week or so after toyota reflash it, and then the 3-4 cold flare returns.

            Have you/they checked trans fluid levels?

              Hi Dandin, yes I have and so have Toyota. Just had the latest ECM update and the issue is still there.

                My ECU update was done months ago, & it still happens to my gear box as well.

                My nephew's 2017 SR5 auto Hilux (bought new), also does it.

                I like my Tuner, but looks like Toyota can't find a permanent fix for several of their problems with the 2.8 TD engine or auto gear box.

                  My 2016 Hilux is doing the exact same thing for 2 years now. It also does it randomly even when the car is warm. I have returned my car to two dealerships over 28 times now including services and I am always told that they can't replicate the problem.....Has anyone resolved this issue with their dealer? or taken any other course of action successfully?

                    Back in for service this week, could not fault it so they reset the memory for a relearn (for the 4th time now) so the 3-4 flare will be back in a couple of days.

                    This time they tried to say the trans will slip like this when cold to warm up faster. I suggested this was ridiculous for one gear change only to flare into neutral, once only when cold, to warm up the trans.,.....

                      Yep, mine still does it now and then, even when I think the car is warmed up. Way back when, they told me its because the engine / trans was cold. Might need a new mouse to run around the wheel...

                        Hi all. Realise this is an old thread but I'm still having probs now & then with gear lag / hunting. So I sent a registered letter to Mr Toyota in Victoria explaining the problem & that my local Toyota mob can't seem to fix it. Will let you know what happens.

                          Please keep us updated.

                          I raised this issued with Toyota several times and all I got was we've applied the most recent TSB.

                          Problem never was fixed. Most noticeable when for example I back off going around a round about then reapply accelerated, the transmission doesn't select a gear and just revs.

                          It was suggested by another mechanic to try simply changing the transmission fluid. I have't done this yet...

                      • #58
                        Ditto Bussa. accelerating around corners, over speed bumps & roundabouts. I've told them 4 times. Latest ECU updates performed, nothing wrong, cold gearbox, tyre pressures to high. Everything accept an honest 'we don't know'. My transmission oil has been changed/serviced by transmission place in Sydney called C.A.T.S., so at least I've tried / eliminated that part.

                        I also sent an email to a transmission guy (in Qld). He rang back saying he's not aware of any problems with the Fortuner, but I did hear a thud & laughter when I told him Toyota said tyre pressures were to high. I think he fell off his chair... said the gearbox in it was an Asian Zeeky (spelling?) brand, not Toyota, but the computer sending info to it was Toyota. Said the same brand box is in several brand cars, including his Isuzu D-Max, but he doesn't have gearbox issues.

                        Will definitely put what Toyota say on the Forum if I get a reply. Sending the letter by registered post will ensure Toyota get it. Up to them to reply!

                          Is the issue accelerating only after de-accelerating, where it is still in a lower gear before changing up?

                          Or is it actually faulting on up changes?

                          Either way I would overfill the gearbox by at least 1/2 litre. A conversation I have had with a transmission specialist is they have eliminated symptoms of cold gear change issues by putting up to a litre more in the box.

                          Worth a try

                          Yes - transmission is a Aisin Seiki who has two major shareholders, one being Toyota...! They are supplied to a whole host of car manufactures. Would make sense that it may not be the transmission unit itself if they are using them in so many other vehicles, seemingly without this issue.

                        Pick your brains time. Does anyone know if the scan gauge can be set to monitor / detect gear box issues? If it can, any stored info could help the Toyota people figure out what's going on.

                        Mine's also be when backing off for corners, roundabouts or speed humps, then normal accelerating... not hard acceleration like you'd kick it in the guts for overtaking.

                        As always, any info / advice is appreciated.

                          doesnt need to be programmed , any active codes will come up right away , something like Pxxxx ( Powertrain )
