problem #2

Sep 082023

Sierra 1500 SLT 5.3L

  • Automatic transmission
  • 71,622 miles

After having the transmission flushed, the shudder still remained along with hard shifting and began sticking in gear while driving. The dealer had my truck from September 8, 2023, until November 16, 2023. They replaced the transmission with a remanufactured transmission. The shudder and hard shifting remained.

Sierra 1500 SLT 5.3L

  • Automatic transmission
  • 82,000 miles

After having the original transmission flushed and then replaced, the same issues were still present. In September of 2024 the dealership said the transmission need to be totally rebuilt. They had my truck again for about 3 months waiting for a valve body. I got my truck back in November, and the shudder is still present.
