Toyota Venza Transmission Problems

wingrwingr Posts: 5
I have an AWD V6. When cold starting I let the car warm up for at least a minute (after work) and up to 3 or 4 minutes, first thing in the morning. I need to back out of my driveway and my space at work, both are pretty level. Anyway, after shifting into reverse (foot on brake), the Slip Indicator blinks for what seems like 5 seconds or more and the car doesn't do anything. Then I'll hear a noise under the middle of the car and the slight clunk of the transmission engaging. Is this normal or is something wrong with the trans or a sensor? Once warmed up, nothing else has ever occurred that would be out of the ordinary. There is only 250 miles on the car since picking it up on Monday. TIA! Regards, Chris

    Hi guys,

    Just took Venza V6 and V4 for test drive. I found the same weird behavior in both of them.
    You drive the car in a manual transmission mode (let's say using 3rd shift) and fully stop (not changing the shift). The panel will still show 3 for the shift and it won't change it to 1 as it used to be in other cars. So, you start driving again and keeps showing 3.

    Do you have the same in your Venza? is it by design?

    HUH? If you have the shifter in 3rd it will not move to 1st. You're still in 3rd at a stop. Just like if you're in D, it does NOT change to 1 at a stop.

    What? How come the transmission doesn't adjust it? It makes no sense to start driving with 3rd (or 4th..etc) gear. Or driving 40km/h after highway in 6th gear.

    I drove audi and hyundai with tiptronic before and they used to adjust it. Yes, It still gives you a feeling of controlling it but it has some protection as well. For example, driving over 6000rpm (in a manual mode) the transmission will give you 1-2 seconds for adjusting and will automatically shift itself up.

    For example, as used by some cars, their five-speed Tiptronic will automatically make the upshifts from 1 to 2 when moving off from a stop, even when in manual mode; the transmission then waits for the user's upshift command before proceeding from 2 to 3, 3 to 4 and 4 to 5, although the transmission will still upshift if the redline is approached. On deceleration, the transmission will make all downshifts automatically when close to the tick-over or idle speed, to avoid running the engine at too-low an RPM, although the user can accelerate any downshift (that would not violate the redline), thus allowing improved engine braking, or preparation for intended acceleration.

    I'll have to agree with anry555 on this one. I've owned several cars with shiftable automatic transmissions (i.e. Tiptronic) and they all "automatically" downshifted to 1st gear after coming to a stop and the indicator on the dash reflected this. With my wife's Lexus IS, the indicator does not change when you come to a stop with the shifter in manual mode so it may appear like the car is still in 3rd gear. BUT the transmission has actually downshifted after the stop so you are really starting up in 1st gear even though the dash indicator continues to show 3rd until you are going fast enough to upshift to 4th or you switch to full automatic mode. Seems like a Toyota/Lexus thing.

    A "true" stick shift wouldn't automatically upshift so now that DBW can be used to prevent an over-rev why not? Same with downshifting...if the engine doesn't knock due to lugging what's the harm...??

    And if it does knock due to lugging DBW can be used.....

    "...Just took Venza V6 and V4 for test drive...."

    That would be i4 and V6. The four cylinder engine is an inline four, not a v-configurated four.

    Bring it in for diagnosis under the warranty. A pause that long, before reverse engages, isn't normal, even when cold starting.

    I have the same car AWD V6 and the same thing happens to me. I just got my car 2.5 weeks ago and the SRS Warning light kept intermittently coming on along with the VSC (Vehicle Stability Control) light (it should only come on when the car is sliding on ice, wet road, etc.). If the VSC light does not stay on, there is no dianosis the car dealer can do! Thankfully the dealer did get the SRS light to go on and they replaced the driver side seat belt mechanism-no problem so far. I still to this day am getting the VSC light indicator when I am at a standstill in my garage and when I initially put the car in reverse (I am not on any hills or inclines when this happens), but once I start to move, the light goes off.

    I have an AWD V6 and have not noticed a delay or the VSC light when shifting into reverse. I have a slightly sloped driveway.

    I have a 4-cyl FWD. When I first start up the car, place it in drive and slowly accelerate away, I hear a soft clunk or thud noise approximate in middle of the car when the transmission shifts from 1st to 2nd. When I stop and then accelerate again, there is no noise as it shifts from 1st to 2nd or thereafter. The noise only occurs ONCE after the engine is turned on. Does this have anything with the transmission or VTC? I read in the manual that you can expect some kind of noise but did not specify the kind or occurence. I'm having it checked out at the dealer.

    I had to bring mine in when my bumper protector came in. The service adviser said the Slip Indicator light and delay before engaging the transmission is because the car is doing a diagnostic test when it's a cold start. Some report a similar condition, others do not. Time will tell if it's really a problem or not. I haven't had any other issues.

    That is probably the ABS brake self test noise that you are experiencing. It happens just as you state. Once after the car is first started and driven for the first time. If you park the car, turn off the engine and start the whole procedure again, it may do another self test.
  • wwestwwest Posts: 10,706
    When you first move the vehicle the ABS/TC/VSC is tested so I wonder if this isn't simply an indication of same.
  • verndogverndog Posts: 6
    I posted another thread with the same issue, I didn't see this. Yes, I am having the exact same issue. FWD V6, TCS light comes on backing from driveway, or after releasing ebrake from slight grade. I get the delay and light and not always when cold either. Its inconsistant which tells me its a problem. If it did something the same each time then I'll buy that as possibly normal. I think the service guys have no clue and since there is "no code" then there is no fix. Dont buy that either, there are "no codes" with flat tires, piston slap, or any of 1000's of other issues, but there sure as heck is a problem in need of fixing. This can be dangerous since the car will just "let go" and start moving since your foot is off the brake waiting to go...and you dont know when it will take off. Sometimes 2 seconds...sometimes 5-6 seconds.

    bdyment:
    Yup, you were right. Took it into the dealer and they confirmed your assessment....ABS self test diagnosis. Odd that it makes that kind of noise, yet my 1997 Toyota Camry with ABS brakes didn't make any noise.

    How did they determine it was the ABS self-test diagnosis? Maybe they read your post? ;) In fact, how did you know? Is there a TSB on file?
  • wwestwwest Posts: 10,706
    Maybe too many owners concerned about the ABS startup noise and so Toyota has added the indication to allay the fears..??
  • bdymentbdyment Posts: 549
    I knew from experience. I have had ABS in most of my cars since 1988. They all made the sound in question. Some of course, a lot louder and more pronounced than others. My two Camrys with ABS certainly made the noise and the most irritating of all was my 2001 Corolla. It was ridiculous. The Fords that we have owned have been the quietest.
  • halwickhalwick Posts: 45
    Now you've got my curiosity. At times it is a soft clunk or slap, other times a definite clunk. How is that diagnostic test generated? Couldn't Toyota have designed it using an indicator light or something? It is irritating, disconcerting and not what I would expect in a $30K car.
  • bdymentbdyment Posts: 549
    It seems that mechanical and electronic parts are moving about during the ABS test. This results in the noise in question.
