I currently own a 15 Silverado 1500 and i can tell you the transmission is no better on this side of the fence. The dealer tells me it's "normal" For the 6 speed and they put that in writing and told me there is no way to improve it. It seems to have a mind of its own. Some days it shifts great. Others, i get loud downshift clunks from the 3-2 downshift. Other times I'm on a back road and the transmission thinks it needs to be in 5th gear doing 35mph, which is luggjng the engine at 1,000 rpm going up a hill (won't downshift unless you really get on it) and that causes a slight driveline vibration. Again, all normal per the dealer.
The 2500 ram i test drove, while it had some of that was not nearly as bad and had a much more responsive throttle without all the torque management BS that gm has in their trucks. So i can tell yall, the grass isn't any greener and from what i can tell is more brown than the Dodge.
It has a lot to do with the crappy TCM programming the government is forcing down the automakers throats to hit fuel economy standards.
I'm not saying this is your issue. However, if your curious, head over to gm trucks.com and check out the 2014-17 Silverado 1500 problems /issues area. There is a bunch of topics there. I have not been on this site long, but these trucks seem to be a whole lot less problematic.
Even the fords have issues with their 6 speeds. From what i can tell, unless you get a tune, which could void your warranty, these transmissions are what they are.
From what i understand, the tundra has a good shifting transmission, but i simply won't own a foreign truck. Yes Chrysler was bought out by fiat (which i hate that they did), but the Dodge is still an American truck in my opinion. To each their own though.
There are lots of folks over on gm trucks Thad have switched to dodge and are very happy. Ford builds a good truck, (not perfect either, they have their issues too ) but they are a lot more money and in my opinion, from just looking at a 17 super duty f250 and is undercarriage, it's not built any heavier than the 17 ram 2500. I simply don't think they are that much better than Chevy / dodge to warrant that much extra money.
I'm considering making the move to dodge myself and i never have owned a brand new mopar product. I did have a 1997 ram 2500 and that was a good truck.
Just my .02 from a different perspective. My Silverado is a good truck, runs fine and is reliable, but it's not perfect. None of them are. Pros and cons to each. But I like what i see in the Dodge. You can get a lot of options in the lower trim levels you have to go to an xlt ford to get.
The 2017 Silverado 2500hd i priced was way more expensive and had a lot less options and was not nearly as heavy duty as the 2500 ram in my opinion (axles, suspension, steering components ) The 2500hd Chevrolet is also known to have some trans shifting issues and some vibration issues. Plus i just like the looks of the ram better then Chevy or ford. I don't care for the front end of the 17 ford superduty at all personally. I like that dodge has stayed with their trademark front end and styling, which was copied in my opinion by ford to some degree when they released the 99 superduty.
Good luck in your decision, but if you went with a gm truck, you'll find things there you won't like also.
