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.

Good job, let us know what happens. We are interested to see what it is.

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.
