Car Shakes After New Transmission

If your car shakes after getting a new transmission, it could be due to a number of factors. Some of the most common causes include:

Improper installation

If the transmission was not installed properly, it could cause the car to shake. This is especially true if the transmission mount was not tightened properly. A loose transmission mount can allow the transmission to move around, which can cause the car to shake.

Damaged transmission

If the transmission was damaged during the installation process, it could also cause the car to shake. This is especially true if the transmission case was cracked or the gears were damaged. A damaged transmission can cause the car to shake because it will not be able to function properly.

Driveline problems

If the driveline was not aligned properly, it could also cause the car to shake. This is especially true if the driveshaft was not balanced properly. An unbalanced driveshaft can cause the car to shake because it will not be able to rotate smoothly.

Tire problems

If the tires are not balanced properly, it could also cause the car to shake. This is especially true if the tires are out of round. Out-of-round tires can cause the car to shake because they will not be able to roll smoothly.

Solution

If your car shakes after getting a new transmission, the first thing you should do is to take it back to the shop that installed the transmission. They should be able to diagnose the problem and fix it. If the problem is not fixed, you may need to take your car to a different shop for a second opinion.
