Dealer invited me to have Toyota Engineers look at transmission

I can recreate my issue very easily. Did it for the tech and service director and he did it for himself too. Accelerate up to 45mph and then light throttle to maintain. Find a slight incline, keep your foot steady, rpms drop to 1100 and the whole truck starts shaking and it won't downshift from 5th without putting my foot halfway down to the floor.

Definitely feel the one just above too where it goes, then pauses, then goes, then pauses. It's from a low speed half+ throttle. It's like the power band has steps in it.

 

This also tells me that Toyota is aware that their transmissions have problems. My dealership says, "it's functioning as it should." What they really mean is it's functioning as it will function. Toyota doesn't give them any options to do anything for certain issues like these. Toyota wouldn't be putting this time in to it if they really believed that the transmission was functioning as it SHOULD.

 

No I don’t think that’s the same issue

 

I feel it in my two wheel drive....

And even if that is it in some cases.... FOR THE LOVE OF GOD... Toyota Dealership Service... FIX IT CORRECTLY FOR US!!!!

 

I get occasional hard downshifts when coasting down hill.

 

That too. Again, at the time I think it was used and I made the change and it just always stuck. Anyway we are off topic.

 

Stay on topic

 

They don't care, they put the right thing in the passenger CV. Why did they not do the same thing on both sides????

 

Even in the 1st and 2nd Gens this was annoying as hell. I can not move my foot on the gas at all, and it holds speed relatively well. How on earth can the CC not figure it out?

Love coming up on hills and feeling the too familiar "oh, we're coming to a hill, just gonna ease off a little bit...getting a little slow...FLOOR IT MOTHERFUCKER!!!" routine.

 

I mean, what would a dealerships options be? It's all up to the tune now to save it. The hardware is set in stone, hopefully the software will shore up the shortcomings of the poorly chosen hardware.

 

Count me in for these issues

1. Gear hunting on hills from 6-5-4 gears
2. Clunk from 2nd into 1st coming to a stop
3. Way too aggressive downshift by just giving it a little more gas coming into an incline. Barely into the pedal at all & hitting 5000 rpm

 

Update to my concern about the shudder/ rumblestrip feeling under deceration/ braking . The vibration pretty much disappears if I throw it in nuetral and use the brakes normally. If it is in drive , it shudders from 30 to 10 mph . This tells me it’s def in the trans/driveline ... not brakes or clamshell bearing ( it does it in 2or 4wd ) pop it in nuetral , smooth as silk ... just wanted to see if others that commented in this thread of a similar vibration had the same situation .

 

The dealerships don't have any options. I understand. I am saying that they have their hands tied. Toyota, though, is trying to do something. They surveyed us and apparently are bringing some of us in to show them the issue. That's great. What that shows is that they know it's a problem. That, like I said, the transmission is functioning how it will function but it is NOT functioning as it should.

 

Oddly, I feel the opposite of #3. Mine doesn't want to downshift unless I put it half way to the floor. Barely in to the pedal and the truck stays in 5th and starts shaking because 5th can't handle it. Crazy how we can be feeling almost opposite issues.

 

Mine doesn't seem to be at quite that wide of a speed band. Mine is more right around 20.

 

THIS!!!!!

 

I had the new TSS done and it works better but my problems is the squishy peddle, and if you give it to much throttle it jumps. As for the 4x4 when off road it truck works like a champ. Took it up to he Sierras about 3 weeks ago pulling a pop up trailer and I was impressed.

 

Count me in for:
1. The hard clunks on the 2nd to 1st downshifts when cold.
2. Make the updates easier to obtain.

 

Has this happened yet?

 

Still nothing?
