No such thing as shifting…
No such thing as shifting without the clutch in an automatic. No matter what position you put the stalk, or paddle in the clutch will engage before shifting gears or from drive to reverse or from 1 through 6 or 8 depending on the gearing. That's the momentary lag you feel in acceleration. You absolutely can not shift your truck without using the clutch. I absolutely could in my 09 sr5 5 speed, though. Power shifting can only be done in a manual without a clutch. Literally impossible in an automatic gearbox. The clutch is electronically programmed to engage without any human interaction.
