I drive a 2020 sonic. I got hpt so I can tune the engine and trans. For some reason it won?t even give me a option to read the trans. I?ve reached out to hpt and they was quick to write me off and tell me it was unsupported but yet every Chevy sonic tcu before mine can be read? The trans hasn?t changed since the car was made in 2012. Is there something I?m doing wrong? I?m still new
Thanks Zack
