Most of the time that I pass a speed bump and I accelerate the vehicle make a weird vibration when goes from the first to the second gear. After the second gear doesn't make the vibration any more.

This SR5 was B rand new purchased in March 2019. It has never been driven off road with the exception being I drive it up a hill to my barn over lawn using 4WD high. I've heard this grinding noise two to three time when shifting from reverse into drive when the truck is stationary and on a hill. I haven't checked if this occurs in each of the transmission modes. I believe I have heard it both in 2wd and 4WD high but have not checked yet if it happens also in 4WD low. This is alarming and for now, I avoid putting it in drive by drifting back to level ground when possible. I am concerned the transmission is being damaged internally when I hear this. I plan to see what the Toyota dealer has to say about this.

This brand new 4runner makes loud groaning sound from the first day until now, every time when transferring from reverse to drive or drive to reverse on a hill road, no matter an alley or a parking way. People who heard of it said it should be a transmission problem and it's bad. Because it sounds like something inside is being broken and not sure when it's totally dead suddenly and the vehicle would lose control. I don't know car. I didn't let any mechanic touch it yet because I'm looking for a third party legally to check it and their report would be also accepted by Toyota. So I don't have any report about the problem now and I don't know what I should do either. But I really want to know how bad it is and if it's safe to drive. I've been told by a Toyota mechanic that another customer who purchased 4runner too from the same dealership shop complained about this sound too. So I report it here. Hope you can help! I have over dozen records of the sound, I'd like to sent them by email or mail to you. Thank you!
