Well i got about 1000 miles on my 2nd flush job with the supposedly new fix all end all fluid. Seems to feel like its doing it again. But now seems like its doing it at a wider range of speeds and gears. Normally when i feel it shudder i can put it in 7th and it goes away. Now it seems like its always doing it. that rumble strip feeling. is there any other driveline issues i dont know about that would be reminiscent of TCC shudder? Thanks group.
