Anyone else running the "Sport" TCM tune? I've been running this setup since Friday and came across a small issue. Curious if anyone else has had the same thing come up?
In NORMAL drive mode during light throttle situations, at about 28-30 mph, it will shift from 5-6 which is just slightly fast per the shift schedule (if i'm reading it right) but then it will almost immediately shift 6-7. Following the shift to 7th it will downshift back to 5th. This is all while applying pretty consistent light throttle. Per the shift schedule, it shouldn't perform 6-7 until roughly 40 mph? I've been able to reproduce the behavior several times. If your driving a little more spirited it seems to act pretty well. I am running 37" tires btw.
Now with all that being said, SPORT mode works flawlessly so far. I am 100% satisfied with how it performs. I have not tried the "OEM+" tune yet...
My truck does this with the stock size tires but at around 45. It will be in 7th then shift to 10th and lug the motor like the OEM TCM tune. After a few seconds it shifts back to 7th. It’s odd.
PM'd y'all with some questions.
