What do you drive? What transmission have you got? How long have you owned it? Has it ever had a performance tune applied? Has the trans ever been serviced? Have you checked the fluid level? Does it do this consistently, or only once? What happens if you clear the code? Are there any other symptoms, like slipping in 3rd gear?
2007 Chrysler 300. Fluid change and filter changed 2 weeks ago. I had my transmission replaced back in 2018 because I had this same problem. 2 years later it’s happening again with the same code? Once I drive over 20 miles my car starts to stall out so I have to shut it off start it back up and get it to accelerate again. No tune up
