Hello,

I would definitely change out the fluid. here is a guide with diagrams below to show you how on your car:

https://www.2carpros.com/articles/how-to-service-an-automatic-transmission

This trans-axle uses GM T-IV fluid P/N 88900925.
Transmission Fluid .................... 7.1L (7.5 Qt)

I would run the codes as well because the input shaft speed sensor can cause this as well.

Check out the diagrams (below). Please let us know what happens.

Hello Ken, how do you do! I made all the things I should do. But at the long distance the transmission still the same problem. And I used 3 liters of the oil you told me to use but I didn't try it yet. So to tomorrow I will talk to you and I will keep in touch. Thank you for your help.

Hello Ken. I drove the car for a distance of 50 km. The problem with the transmission did not solve it, but it got smaller when the gears changed. What should I do? I want to tell you that I only put 3 liters of oil. But the extracted quantity was 4 liters. How much is the transmission capacity?

The transmission capacity is Transmission Fluid. 7.1L (7.5 Qt) Have you run the codes it sounds like it could be an input shaft speed sensor. Here is the location so you can check it out. Check out the diagrams (Below). Please let us know what you find.
