Hi all, I'm new here and hoping y'all will be able to help give me some direction. I have a '15 Yukon XL Denali with the 6 speed MYC transmission and almost 140k miles, my transmission has begun shuddering when I'm driving between 25-35 miles an hour, does not seem to do this at really any other speeds. I spoke with a dealer who said their suggestion is just to go ahead and replace the transmission, this feels a little extreme at this point since Im not having hard shifts etc. I've owned the vehicle for the last year and put about 27k miles on it in a year. I have no records of any previous transmission maintenance and the fluid looked good when we purchased it. I know that dropping the pan is a pain in the neck, but I'm thinking that I need to change the filter since I have no idea how old it is. Husband is out of town and I'm wanting to get this dealt with ASAP. I'm pretty capable of doing a flush or dropping the pan if I have a good write up to follow, so any advice would be much appreciated. Also, what fluid have y'all had good luck with? Thanks, Jenn -
I just purchased a 2011 gmc 2500hd Denali with 157000 miles on it. When the rpms are just below 2000 the needle spikes to 2000 and drops back, as if surging. It downshifts fine. If you try to gradually accelerate at that point it shudders as if in to low a gear. I have not tried pulling anything with this truck yet, but wanted to get an idea whether or not I have a serious problem or not. I took it it to a dealer to have a diagnostics ran on it and the tech couldn’t get power to the tester, so before I tackle that issue I wanted to see if I had a major issue. According to some of these forums this looks to be a issue on a lot of newer trucks. any experience with this issue would help. Thanks
