Original Problem: Coolant leak under the supercharger, the coolant Y pipe needed replacing and new updated part , Tore engine down below to bare bones to replace.
Solution: Completed no more leaks or smell or coolant on engine

Secondary issue: After repair the car will auto shift on its own at 3000 RPM even in manual (paddle shift mode and stick mode) I can force it but again not what it is supposed to do. At 4th gear and 5th is burbles / power stutter like it is not getting oxygen or power stutter then if follows through on weird power band.

Resolution items done so far to diagnose: checked all lines for disconnect (without removing S.C.) OBD flash to remove errors and test drove same issues

NOTE: GOOGLE SUCKS, nothing to find in a proper method for issues or solutions. Notated possible issue from research of SuperCharger belt or seals may be an issue, taking it back in to my mechanic to take off and reseat Throttle body and ensure all belts are how they should be.

NOTE2:Trying to avoid going to the expensive Jaguar Dealer as last resort as they would bleed me.

Open to ideas, suggestion, experiences and or resources to properly see what can be done to resolve this issue
