They tell me the shudder I am experiencing is due to the 8cyl., wanting to go to 4 cyl. when I first start up my vehicle after it sits for a period of time. I notice this at around 30 to 35 mph. After a short period of time, it will not shudder
Responding to these comments about the shuttering
My trans failed (Torque converter ate it's self. After have the trans rebuilt. But before that I have had issues where the intervals of trans oil service were getting closer together
I had noticed the temp of the trans oil hovered around 190 + and when I was pulling my motor home the temp would go over 210. After the rebuild I was still having the same issue with the temps. The thermostat was full of the torque converter. The replace it and the temps came down to the 140 to 150 and pulling the trailer would jump to 180 with the trailers. Now because of the temp issues I had the rebuilder lock out the slipping program built into the software. it shifts more like a manual transmission Now. This also lowered the trans temp because the slippage was increasing the temps.
About 5 k after the trans was rebuilt the shuttering developed. It went away at 74 mph
They told me that the left motor mount was broken causing the shuttering.
Just had the mount replaced and the shuttering is still present.
Only my Shuttering is happening now in V4 and V8 mode
I've noticed that I have a low RPM miss this will cause the shuttering #1 #2 & #8 cylinders
one of these cylinders are the V4 mode
Follow up if replacing the injectors fixes the problem
