Hear me out; I know it doesn't make any sense, but it's definitely true for my car
If I drive with the A/C on, the upshifts and downshifts are smooth and don't give the jerky motion a lot of us experience coming to a stop, especially with the Type S.
Once I turn my A/C off, everything changes. The downshifts are more noticeable/engine braking, when coming to a stop, regardless of incline (Grade Logic) and upshifts are a little more rough.
Could anyone explain this? Is my Serpentine Belt tension a little off, or just belts in general? I'm thinking once I turn my A/C on and there's load on the drive belt (serp), it triggers something.
Any thoughts appreciated....
