Slight jerk?

[MekstingerGT]

So took the stinger on a road trip from San Diego to Arizona and on the way I notice a slight jerk around 1500-2000 rpm. I think its shifting up from 7th to 8 gear or its shifting down. Theres no sound just slight jerk. You can definitely feel it through the pedals. It only happens on comfort mode NOt any other mode.

Have you performed any mods lately?

Was it accompanied by a jump in engine speed? Torque converter lock-up perhaps?

Just the jb4 but had it for 3 months no issue. Its weird cruising around town never notice it.

Actually yes notice it when it accelerating between 1500-2000 rpm. Didnt think of the Tc locking up but why so aggressive? It's more of a shudder than a jerk.

There's a chance that it is a defect somewhere around the TC; could be fluid, could be a manufacturing problem, loose flexplate bolt, etc. GM has been going through an iteration of ATF to fix shuddering and Toyota has a "flare up" problem. Who knows what this transmission has.

And you did upgrade the plugs I assume?

Yes I am. Could it be a plug issue? If it was it would have problems through out the rpm? Like I said it's not that bad. Ill just wait to see if it goes away or gets unbearable. Just want to know if anyone have the same issue. I'll report back if it gets worst.

Did you ever find resolution to your transmission shudder?
