I swapped a th400 into my 02 camaro M6 and I have been trying to get the speedo working! I had the electronic speedo parts installed in the transmission, but the software will not let me change the values to correct my speedometer. I even tried entering the calculated values from an A4(4l60 and th400 use 40 tooth wheel) tune into mine and it shows tire size error. Can this be done or am I going to have to just keep changing the final drive ratio until teh speedo is accurate!
I have been searching and reading over the past couple of hours so please don't tell me to search because pretty much everything that the search engines brought up on this forum and ls1tech have not worked!
Thanks
