The car is jumping a little when shifting gears?

Hi,

By design, the transmission downshifts when you release the throttle and slow down. However, you normally wouldn't feel it.

Have you checked the fluid to make sure it is both clean and full?

Also, the idea that it only does it in 4th gear is odd. It could even be a failing universal joint or center bearing. In pic 1 below, I highlighted the center bearing and both universal joints. You can inspect those for evidence of wear. Also, pic 2 shows the carrier bearing. That can certainly cause what you described.

The bearing in the carrier is mounted in rubber, so check to see if anything is worn or loose.

Let me know what you find.

Take care,

Joe

See pics below.

Hello,

It jumps a little when shifting up in gears also. Now the steering wheel has started turning after I brake from a higher speed and come to a stop, and if I let it go, I can see it steering by itself to the right and I have to pull it to the center before the car goes that way. What has started causing this?

Hi,

When the steering pulls when braking, in most cases either we have a brake caliper that isn't fully releasing or one that isn't as well as it should.

If you lift the front wheels off the ground, do either seem to have an excessive drag? Also, if you have a helper, lift the vehicle, have the helper press and release the brake while you confirm it releases properly.

Try that and let me know the results.

hello,

We have not been able to check any of the issues with the transmission or the brakes as it involves getting under the car or manual check and since we are partly disabled and seniors, we cannot do this. We will have to take it to a repair shop for diagnosis.
Thank you

Hi,

I understand. If you have a chance, could you let me know what they tell you? I'm interested in knowing.

Take care and I wish you a great Christmas!!!
