Titan supercharger


New Member
Anyone out there to help with tranny question? I put a supercharger on my titan. Uprev dyno sfter installation. Havent got on the throttle. Tranny wont go into 4th. No tranny issues before my engine rebuild and supercharger installed. Dyno guy did something to get it to shift into 4th. Got it up to 80 mph. Loaded back on trailer and brought it home. Finished some front suspension work and went for a test drive. Wont go into 4th. Ideas?

Not a common issue on a supercharger swap, but it may require a new tune (must be reprogrammed for a new operating mode).
