I’m great at carburetors. Especially the Holley 4 barrel carb. Trial and error made me good at it. I had the freedom to try. We no longer have that. So, yes, all digital tech. Just electromechanical so we can save huge amounts of dollars by not getting involved in the “repair industry”. Transmissions are a different beast but if all the “Chilton’s’” auto repair manuals have not been secreted away and completely destroyed then I at least have a fighting chance to figure it out.
