Gas pedal recall with reflash; seems to fix shifting too

    I haven't gone out and done an exhaustive test yet, but driving around town since picking my truck up last Friday, it seems that the ECU reflash that they do for the pedal recall fixes the "slow corner" downshifting problem (where it would shift down and then rev really high while accelerating).

    When I went to pickup my truck after having the leaf spring TSB done and them cutting my pedal without my permission... They told me that the TSB reflash didn't apply to my truck. I told them when I dropped it off what it was doing (I had this exact problem with shifting) and complained that I needed the ECU reflashed per the TSB. The tech informed me it has the latest software update. I kept telling them how it was shifting and that it's not normal.

    That's when they told me about the reflash that was done along with the pedal being cut. I simply thought to myself, I'll just drive it and see what it does and come back and talk with a manager if I have to.

    Well, guess what... It shifts perfect now. WTF? Did just reflashing the ECU with the recall update recalibrate the computer? Was there additional updates included that their not letting us know about? I have no idea, but the problem is gone without explanation.

    I would think that they have simply fixed both issues in the current software revision, and if you fix one you fix both.

    That's kind of the way the ECU flashing works; it's like upgrading from Vista to Windows 7, you don't just upgrade one component, you do the whole thing.

    Question about the ECU flash, does it implement the brake override on the throttle?

    I bought my 10 to be able to do some offroading with it and there are times when you want to be able to apply power while holding some brake.

    Do they do the reflash for manuals? I got a notice and cant decide whether to get it done.

    Does anyone know the TSB number or where I can find a copy of it to bring in when I get my oil change done next week? They have been hounding me about my gas pedal and I'm about to just give in so they quit bothering me about it.

    Well, my truck is at the dealership right now getting the first oil change and I asked them to check the rear spring TSB and they brought up the gas pedal recall. I have already called them and told them they could cut the pedal but not reflash the ECU until I find out more information. I'll talk to the service manager when I go back to pick it up to see if he has any extra information.

    You know what they say when you ass'u'me.

    Really?

    I got the gas pedal notice in the mail last week and wasn't planning on taking my truck in to get it done... BUT now that I hear that it also fixed that annoying "slow corner" shifting issue (as you described it), I might have to re-consider it. As far as the gas pedal trimming goes, how much and what exactly do they trim? I've never had any issues with my gas pedal so I really don't want them to change anything... Any pictures of the pedal now that they trimmed it?

    That is my issue too-the gas pedal is no where near my Weathertech mats, so I don't really want them trimming it. However, occasionally, mine will do some funky down shift when slowing down and rev up quite a bit. It would be nice to have this condition improved or eliminated.

    I never got the recall notice. That sounds like the exact information I was needing. I appreciate it.

    You may be right, but the normal ECM TSB is NOT specified for my truck.

    If it wasn't for the pedal recall, my ECM would NOT be updated and I would still have the transmission lagging issue.

    From a document posted here some time ago, the brake override kicks in only if the throttle was applied first. This is to facilitate starting on a hill, heel-and-toe on the track, etc.

    My dealer had sample pre- and post-rework pedals at the service counter. They trim back the pedal face up to the first rib.

    My truck is there right now getting the recall done. I was in hopes that the flash would fix my shifting problem. That's the only reason I bothered doing the recall in the first place. They refused to do the tranny flash months ago so I'm hoping this will work. I'll let u guys know when I pick it up.

    I'm going to go out on a limb here and say that IT WILL fix the problem. ;)

    I had my 07 in last week. What I was told was that the override will not kick in unless you are going 30MPH, and you mash on the brakes. This will disable the throttle.

    For the gas pedal, I was told it was 15mm that they trim. They mentioned the ECU Flash, bit nothing about the shifting issue. I did not bring it up to them, as they seem to not like to perform TSB's unless you really hound them to do so. I am glad to hear that the reflash fixes the shifting issue.

    i have an appointment set for next monday. my wife is taking the truck for me. i could care less what they do to the pedal. i rarely see it, and the bottoms of my feet arent that particular. i suspect i hardly notice the diff.

    just in case..in the long shot, something does happen..i want to reserve the options i have. i dont want to give them the chance to say..i turned down anything.

    the reflash is cool.

    Ok so I picked up my truck. I didn't get to drive it much but so far so good. I notice it doesn't feel like I'm driving in neutral anymore for a few seconds like it used to. I can tell cause my exhaust is alot quieter. I'm driving a 1300 mile trip in a two days so I'll really get to test it out. As far as the pedal cut it looks pretty smooth to me. I've seen a few pics of others that looked alittle "butchered" but I'm ok with how mine turned out. I just hope it's not too short and gets caught on my weather techs

    There is a TSB for the 2009 and 2010 automatic transmission shift issue. But not for earlier models. If this 90L campaign does indeed modify your tranmission shift points then it would be news here.

    Here is a diagram flow chart of how the new logic works for the brake override system.

    ToyotaBrakeOverideSystem.pdf

    I got it done on my 2009 and I have nothing bad to say about it.
