Replacing TCC solenoid, experience with GM5 transmission

this is what mine is in the shop for right now. Not a reverse issue but a slow to build pressure to go forward issue.

Are you doing the same TCC solenoid replacement? Please post updates when completed. I'm starting to run into the same issue (slow to build pressure to go forward), but only when it's cold and/or the car have been sitting for more than a couple of days. Thanks.

Yeah. I thought that they were going to update the trans software based on the research I had done but the service manager said the solenoid was causing the pressure in the trans to be relieved over night. I get the X back on Monday so Tuesday morning will be the day of truth. We have been dealing with the issue for almost the entire time we have owned the X 2 years now. I will be glad once it is running right.

Thanks for the post. I am sure this is in my future some day.

Here are pictures of the solenoid, just after it broke in my hands. You can see the cracks on the 2nd picture, just waiting to break at any time...
