If the issue is with the 10R80, slamming into gear when selecting a gear off of Park or going into Reverse it is not normal. As mentioned above it can be indicative of the clutch assembly failing OR possibly one or both the other most common issues with the 10R80:
- Low fluid from the factory. Check your fluid levels when the car is at normal operating temp.
- Bad or failing valve body.
Go to this thread which is one of the largest threads on here with 10R80 info that contains many links RE: common issues or upgrades with the 10R80. The link for how to check the fluid is also in it.

It’s best to schedule an appointment to have the car looked at because the slamming in gear is t normal and if not addressed it will just get worse.
