I know this is an old subject but after all these years is there a consensus on an established root cause for the 1-2 "nibble" on my 2011 GT with the early MT82?
On my car it's always been there mostly unchanged since I bought the car with ~25K miles. Currently at 160k. It's always been hard to shift 1-2 when cold so I go 1-3 (which is fine) until things warm up. 1-2 is better when warm but will still nibble if I go straight 1-2 shifting at lower rpm. Shifts smoothly if I let it the shifter drop briefly into neutral between 1 and 2. The 1-4 skip shift feature is untouched and the light occasionally will light up on the dash but I get the 1-2 nibble at lower rpm regardless if the skip shift light comes on or not. Oddly, the 1-2 shift is perfect when warm if I wind out 1st a bit, at about 4500 rpm or up it goes 1-2 just perfect. All other up and down shifts are fine. Hasn't gotten worse or better with age. Currently running BG Syncro Shift. Compared to factory fill, the BG seems a little better when warm and a little worse when cold.
I'm confused why 1-2 is fine when winding out 1st but is crunchy when I shift 1-2 at low rpms? I can understand and am okay with shifts being notchier when cold of course.
Does this seem like a 1-2 syncro issue, a fluid issue, or something else? And could the 1-4 skip-shift feature possibly have anything to do with this if the light is not coming on on the dash? Is there some mechanical aspect to the 1-4 skip-shift feature that could be causing this 1-2 low rpm nibble even when the skip-shift feature isn't activating (at least not according to the dash light)? And would the upgraded syncros in these MT82 upgrade kits be a benefit?
Thanks for any help or advice, much appreciated.
