Those with 8 speed shudder problems?

Fabricator19 · October 2, 2019

I was told by the tech that GM requires waiting 200 miles for any further service, so at 201 I’ll give them a call

Think I have been hit by the torque converter issue. I’m outside my warranty as I have 64K on a 2017 1500 6.2L. Anyone have insight on how much this is going to cost me?

17 Sierra Denali 6.2 4wd 64k miles at the dealer right now for the shudder problem. Just got a call saying that they want to replace a transmission harness and temperature sensor for $1100 to fix the problem? Does this make any sense? Another $275 to install pads for the leaf springs to fix the clunking noise.

Chederd did it help?

I had the 8 speed fluid changed yesterday. Initial drive home and around town it seems much smoother. The 2-1 clunks are still there but are way less harsh. 2/10 vs 6-8/10. It seems to slip less when accelerating from a corner. It also seems to shift quicker on hard acceleration.

Could it be in “test drive” mode? Or still in a fresh re-learn?

Either way its better. Its worth the time and effort to get it swapped.

Dont waste your money on those pads....get some rubber from amazon or bicycle tubes and stick them in there, pads were useless. I dont know about the tranny stuff, mines been flushed 3 times by the dealer and it still shudders.
