possible 6R80 woes?

[mazroth]

My car: 2011 base model auto GT. Roush TVS with vmp tune. Stock pulley, 1-7/8 kooks, kooks hpipe w/cats, dynotech alum ds, gt500 mufflers.

Its not a DD, vacation car and pleasure vehicle. 14k+ miles. Past few weeks, was on vacation. Went on a trip to TN. Up and down the mountains all week long. When driving thru town, I started noticing when it shifted into 6th, it felt like it was sorta slipping(like it would rev a split second).

Back at work, and catching up on chores, havnt had time to take it back out yet. Thoughts?

14k miles with only a tvs, Your stock 6r80 should be having no issues.

Its hard to dial in good shift points and when cruising in town depending on how fast your going, the car should not shift into 6th anyways. The shifting back and forth could be the up shift and down shift points for that MPH and Throttle % are just too close. Contact your tuner and possibly do it while logging.
