Is there anyone that understands the 2015.5 - T87 transmission TCU code enough to do the inevitable and run the 8l90e standalone behind non chevy -B.O.P. ENGINES with a controller like tci or know of aftermarket efi ecu that will work in conjunction with t87? Holley has a efi ecu that runs a old trans
Please no discussion on ancent 4l80e trans based on even more ancient th400. The cost and effort of 4l80e to only gain overdrive is not logical. 6l90 is a light duty trans. My Olds will dictate a heavy duty auto and the 8l is that trans.
Thank you for any help
