When I speed up to 30 to 40 km it begins to vibrate like the propeller shaft. But I have changed the transmission rear seal and the support. But the vibration does not change. Now When the truck is in drive it keeps accelerating but doesn't want to go.

Hi,

When you say it keeps accelerating but doesn't want to go, do you mean the engine continues to rev but the vehicle doesn't accelerate normally?

If that is the case, start by checking the transmission fluid for level and condition. If the transmission is slipping, it can cause a vibration.

Let me know.

One time water was mixed with the transmission fluid. I have flushed it 2 times already. But the vibration is still there. And now it's like the transmission is slipping like you said.
Do you think it's the transmission solenoid?

Hi,

Is the fluid clean and full? As far as a solenoid, in most cases, it will set the check engine light. Is it on?

If it is, scan the computer to see if there are any codes specific to the transmission. Actually, scanning the can-bus would be a good idea.

CAN stands for controller area network. Basically, the different control modules are tied together via a few wires and communicate with each other. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it is done:

Let me know if that is something you can do or have done.

Take care,

Joe

Hi Joe,
You know about one year ago and still now, I had problem sometimes setting my Tundra truck in drive gear
It was so hard to shift it in gear, I had to pump on the break padel 2 -3 times to set it in drive gear. And sometimes you hear a bang sound like metal-to-metal slam on each other.
Now the mechanic told me I have to buy a new transmission Control Solenoid. Let's see if the problems will be solved.

Hi,

Thank you for the update. Let me know if the solenoid takes care of the issue. I'm interested in knowing.

Take care,
