What does it feel like, is it a vibration felt through the gas pedal at slow acceleration? Thanks, Douglas

I feel mine through the body rather than through my foot on the accelerator. (The Nitro is fly-by-wire in this respect.)

I would describe the shudder as feeling like either the engine is luggung (RPM too low) or as the clutch slipping (if using a manual tranny and shifting with not enough RPM for that gear).

Yeah, that's it! do you feel it all the time? It does not happen on mine every single time, only once in a while and usually only in first gear. Thanks, Douglas

Nope, not every single time ... but most often when I'm trying to add power at the same time that the TC is trying to engage.

(You'd get the same thing on a stick shift if punching the gas as you were letting off of the clutch!)

Friend Joe, same exact thing with mine, you describe it very good. I wonder what TSB-18-027-08 does? I think it's for TC shudder but it also has something to do with the air condition? Do you think this TSB is just a computer re-program or is it something mechanical/hardware? Thanks, Douglas

TSB-18-027-08 is only a computer upgrade, no parts involved. I have the shudder problem betwen 40 and 50 mph. No problem with a shudder relating to A/C. I too wonder if this Star Scan would help my problem.

The dealership did TSB 18-027-08 today, we'll see what happens. Thanks, Douglas
