722.6 drops RPM during 2nd gear is normal?
RPM drops and I feel car accelerates much better than before dropping.
Feels like I have extra gear between 2 and 3.
And if I put my transmission to S mode it doesn’t do this, smooth RPM increase.
During winter, it makes small impact for first few times on 2nd gear accelerate and goes smooth.
And all time, after shifting to 3rd gear it goes super smooth for 3-4 and 4-5. Only for 2nd gear starts. (Comfort mode)
what can be go wrong? Torque converter? Lock up clutch solenoid?
Changed fluid on 40K and 70K, TCU reset by dealership performed, Diff fluid and transfer case fluid serviced.
Theres one time that I mistakenly changed to gear 1 during downhill about 30-40mph but not sure that single impact caused damage.
Here’s a video.
