I have a 98 F-body running on a 411 pcm 12212156 OS 2 bar SD tune. I recently swapped from a 4L60 to a T56. Id like to do a segment swap to try and get things working properly. I cant seem to find a manual tune with that OS. Can anyone help me with a solution? Any vehicles with that OS come with a manual trans?? Not sure where to look.
Thanks
