My Car Shakes Noticebly when I Put The Gear into Reverse When The Car Is on a Slope, Is This a Serious Problem?

[Deactivated] on 10/11/2014 - 16:05

I have a Toyota Yaris with automatic transmission gearbox.

Today when I wanted to put the gear into reverse in order to reverse against an slope, the car made was an odd, loud sound and shook quite noticeably. Then I parked the car upwards, and tried to reveres, same result.

Please watch the following youtube shot I got to see for yourself what I mean.

https://www.youtube.com/watch?v=jSMwzYI3deY

From the video you can see how the car actually shakes.

It always happens for the first time I put the gear from P to R. After I put the gear back to P gear, one of the two scenarios below happens if I want to put it on R for the second time:

1- if I keep pushing the break pedal from the beginning until I want to put the gear back to R for the second time, car doesn't shake for the second time I put it on R. (no handbrake)

2- if I take my foot off the break after putting the gear back to P, then the car goes forward or backward a few centimeters depending whether I have parked the car on the slope upwards or downwards (no handbrake). Then, if I put the gear in R again, the car shakes once again.

Can anyone tell me if it's a serious problem?

Thanks guys,

Automotive

    Could just be struggling for power if it is a steep slope. Poor Yaris.

    Otherwise take in and get mechanic to check and top up tranny oil.

      "tranny oil" lol

    When was the last time you had your car transmission serviced?
    Check your car manual, but I change mine every 40,000km.
    I get mine changed for around $70 inclusive of oil and labour.

    Servicing the transmission more regularly may cost more in the short-term, but it beats having to replace the transmission which can cost in the 1000's.

      Incredible good price. My car dealer charges $110 for putting a clamp on the transmission hose. $180 for autotransmission service + parts. interested to know where your mechanic is.

        Website says from $80 for transmission service, but if you do regular business you can talk to Fred for a lower price.

          Website says from $80, small word that makes a big difference lol

        • Cheapo333 on 11/11/2014 - 13:29

          Just give them a call and say another place is doing for $70, can you match?

          These are basic haggling(bargaining) skills.

          you are worried about "from" … pppftt..

          such a n00bcake.

          @Cheapo333: i just cant seem to haggle with mechanics for some reason, so I DIY at home. So $30 per auto trans service and free fluid check and top up every 10,000km

  • King Tightarse on 10/11/2014 - 23:35

    Yes, its a serious problem.
    Its hard to see with that tiny youtube clip but it may well be a gearbox mount. Alternatively, the fact that it seems worse on an incline could suggest very low fluid levels. Does it "clunk" when taking off?
    Anyway cars don't heal themselves, they just get more broken, so get yourself to a reputable mechanic for a quote.
    Hint:
    Many suburban mechanics have a reputation to uphold as opposed to inner city barns or chain workshops that couldn't give damn. I would look for a suburban mechanic at least 30+ with a decent local reputation.

    Did this happen after a cold start or after engine has warmed up? (Trust me, there is a difference) How many k's have you put on this car? When was the last time mechanic did something with the transmission? Do you want to check auto trans fluid condition and level? I can run you through the steps, quite easy, a bit similar to engine oil check

    I agree with what KTA says. My take is if it doesnt do so on the normal flat road, and gears shift normal from 1 to 4 (overdrive) then it would more likely be fine. Toyota gearboxes wont be silky smooth but it last longer, silky smooth gears are weak.

    There is a problem, but not with your gearbox.
    Because your parked on a slope, the weight of the vehicle is putting pressure on the gearbox, so when you take your car out of park, you are releasing the weight and pressure. This is why point 1 and 2 in your original post is happening.

    The real problem is that you are either not activating the hand (park) brake tightly enough, and/or not activating the hand (park) brake prior to putting the vehicle in park, and/or your hand brake is not correctly adjusted (or worn out) and is slipping under the weight of the vehicle.

      It is a valid point i reckon. I remember if i park vehicle at slope. Put into park, no hand brake, let off foot brake, vehicle will roll slightly and engage in park gear (this is one way to test park gear btw as per factory service manuals). From there, when i start vehicle again and put it in reverse, it will 'clunk' or 'thud' noticeably more than usual.

      So if i understand correctly what philthis has written here, try not to let vehicle engage in park gear when you stop your vehicle by fully applying your hand brake before you let off your foot brake, so vehicle doesnt move in P
