I took my car for a test drive today and when I decided to give it a bit of gas it went back from 4th to 3rd which is normal but at 4500rpm it slipped big time. Maybe 2 seconds then it started to grab again. Checked fluid level, just right, i'm wondering if its normal or I need to adjust either the kick down band or the line pressure in the valve body. Any thoughts would be much appreciated.
Would it be better to be in overdrive then go hard so it goes back to 4th instead of 3rd?
