Their is nothing to report, it is normal, saves the brakes. Stops the car from running away down hills.

Re: Engine/Transmission Hesitation

Ok, well my transmission issue with downchanging is still there, and is certainly not right, I have a further question someone may be able to help with.

When coming out of a corner at slower speeds, 30 - 50ks or so, and accelerating out of the corner, the drive (Read:engine & Trans) consistently has a hesitation or stutter prior pulling on again at given acceleration.

Anyone else experienced similiar ? Was this issue a characteristic of the 120 D4D also ?

Based on the downchanging issue being somewhat resolved, the hesitation issue is now the main concern.

This cannot be normal, and must have something to do with Traction control and engine/gearbox mapping needing a tweak somehow ?
Any thoughts on this peeps? Has anyone had any success with their dealers on getting rectified ?

Re: 5 Speed Auto, downchanging

Yes, sorry that what I meant, the lag when you go around the corner, not the down changing I guess you need to report it to Toyota customer service and yourt dealer

Is it not a bit of turbo lag?? Mine is a petrol so not sure issue is in the 120.

Defnately not a problem with my 120 D4D.

Re: 5 Speed Auto, downchanging

G'day Hutch & Leachy,

Definetly not turbo lag, it's like an outboard reacts when its running out of fuel, sort of like, I might go....Hang on......Yes I'll go now.

Turbo lag really relies on awaiting for turbo to wind up to get that power and torque coming, this is a hesitation, which is very annoying.

I think it may only be in the diesel auto though, hav'nt had any comments from v6's as yet on here !

Re: 5 Speed Auto, downchanging

Hi all again
This needs to be reported to your service manager and Toyota Customer service web site so it can be fixed, its a $70000car!!!!!! and it shouldn't happen. The more poeople who report it the more chance it will be fixed. Tell them about the complaints you have heard, I centainly will be.

Re: 5 Speed Auto, downchanging

I have had this exact same thing too, most noticeable when coming out of roundabouts. I had my 1000kms first inspection today and reported it, on pickup of the car they said it was all to do with the electronics.

They said that the computer 'learns' driving styles and it could be getting confused if there is more than one driver, which there is of course. They reset the electronics in the hope that it will re-learn my driving style again. I am not too hopeful of the outcome, still noticed some hesitation occurring on my drive home from the dealer but will see if it settles after a while.

I also found that if I turn the Traction control aids off the problem seems to go away but that could be a coincidence

Re: 5 Speed Auto, downchanging

G'day Davidsford,

I agree, turning the traction control off does alleviate, but not eliminate the problem. I've been the only driver of mine (99% of the time) and
all I can say is, it must be a slow learner ! I have found an older post detailing a V6 Auto 150 also experiencing the problem, so suspect it's across the Autos.

As someone mentioned, nearly $70K on a car, the problem needs resolving, and it really pisses me when dealers give the answer that does'nt resolve the
problem.

I'm up for my 10K soon, and will be looking for a solution.........Hope i'm not Dreamen ?

Cheers, BenTas

Re: 5 Speed Auto, downchanging

I complained about it to the dealer - unfortunately I was told all were that way and it was normal. Since I have only driven mine, a V6, I can't verify if that is true...

Re: 5 Speed Auto, downchanging

Had a service done today, 8k, and had the auto update (remapping fix for overheating), and all seems good so far.
It would seem the whole vehicle is more responsive to the right foot, even when you give the accelerator just a little dab, it transfers more prominantly to
forward motion. DId'nt have the overheating problem in the past, but doing some serious towing this week, so will find out for sure.

Also got the Seatbelt bleeper debleeped, was'nt a problem for the service guys, they were only to happy to help.

Cheers

Re: 5 Speed Auto, downchanging

That's good news - Toyota has scheduled my VX-L for Thursday for the recall reprogramming - maybe other fixes were incorporated (I have about 30K on it so far) - OK, so it doesn't hurt to dream

Re: 5 Speed Auto, downchanging

Towed 2 and a half tonne trailer, and at least another 800kg in vehicle from Hobart to Agfest (Northern Tas) today, and she went like a steam train.

Up over two of the biggest hills in tassie midlands (Spring and Constitution hills), back to 105 ish at the top, and gave her a fair belting most of the way sitting on just over 110.............No sign of a light or overheating issue the whole way

Looks like the fix works, and the hesitation seems to have been alleviated but not removed.

Very happy with how she's going though.
