Hello
My project, 1989 gmc sierra 454 engine swap with 4l80e.

Welcome. Are you installing a TBI or PFI version of the 454?

This time i think i choose easy way, holley sniper and hyper spark. I thin wrong because i still have stock transmission controller and no idea how transmission work with sniper

Sniper won't talk with stock transmission controller. The transmission controller needs to know the engine is running in order to control the transmission.
