Looking for some guidance here, I know this has been asked a million times but my symptoms are a little different this go around. I owned a 2016 Silverado whose TC failed at 120,000 miles. Replaced it and didn’t have any further issues until I sold it at 190k. now I have a 2017 Tahoe z71 with 85k miles that I bought from a family member. I’m noticing the rumble strip sensation every so often and wondering if this is my TC going out. I notice it the most when I’m gently accelerating, between 30-50mph, especially when going up hill. the rpm’s are generally between 1500-2000 and they jump a bit when the shaking happens. the transmission fluid and filter was replaced about 10000 miles ago. is this a sign my torque converter is failing? if so, should I go ahead and replace it so that I don’t run the risk of further damaging the transmission? anything else I should try first? thanks in advance!

Did you end up deciding to put a block in the back? Did you have to recalibrate speedometer with that tire size? Looking at pretty much doing this exact setup on my 2016 z71...5100's on all four, 2" RC block, and 275/70R18 ko2's
