$0D and 1998 4L60e

Maybe a Stand-Alone Transmission Controller is an option?

Maybe two computers '7427 for the Engine and an OBD2 computer for the Transmission?

Link is for the 4L80E, but can also be configured for the 4L60E https://sites.google.com/site/sloppy...ans-controller

Thanks Dave for your attention!
A second computer for the tranny seems expensive and a little complicated to me, but it's an idea to consider.
