Slight studder

[Madenstl1]

I have a 2012 SHO with135k on it. When I accelerate im getting a lag. Doesn’t feel like a transmission slip. I just had it checked. Mainly from 1st to 2nd gear then it pushes through and accelerates and rides fine. Happened today at higher speed could it be CV joints? Fuel related ? I replaced plugs and had tranny checked?

Boost leak? At 125k, it would not be unheard of to have a small leak somewhere

I thought it would throw a code ?

Not always. If it's small enough or in the right place it won't pick it up. Noisemaker on mine leaked under load and I never got a code out of it.

Did you check the hose I posted in your other thread?

See my reply. This does sound like torque converter. If you don't feel it anytime except harder accelerations, it's likely. It's also possible to avoid the issue for a considerable amount of time by not accelerating hard. But eventually, it'll be a replacement need.
