Any transmission issues?
Am I correct in interpreting that the F-250 and F-350 use different transmissions? Does the diesel use the same transmission in each chassis?
The real question: Have there been any transmission issues in the F-250 6.2L? Apparently it's a slightly lighter duty transmission?

Nope. Just the 4th gear shaking bit, but that's for the diesel transmission, and extremely rare. Transmission is good to go. Best 3/4 ton trans out there, right now.
It's a lighter duty engine, with different transmission needs than the diesel. The 6.2L is noticeably better with the G trans compared to my 2015 6.2L work truck.

The Diesel and gas tranny are essentially the same transmission. I believe more shims and maybe friction plates. But both are 6r140. There is a thread with many of the TSBs for the ‘17 and some ‘18. I can recall a recall for a weak plate for the park assembly on the 17. There have been many that have a “normal ticking noise in the 6.2” and as just stated above, a fluttering/ticking/chattering noise heard in 4th or 6th that is apparently related to shift cable that is to short and causes sound transmission up into the cab. (Still waiting on a TSB)

F-250 diesel, F350 gas or diesel, F-450, F-550, F-650, F-750: 6R140, aka TorqShift 6. There are some variations in this transmission when used in a 350 gas truck, or a 650 / 750 truck.
Is is possible it just seems that way because your 2017 engine makes 25lb-ft more torque and at 700RPM sooner, and in a lighter truck when compared to your 2015 work truck?

Ok. I guess I’m way off here and apologizing in advance but aren’t we talking about the ‘17-‘18 SDs (6.2 & 6.7) and they have the 6r140? They just shift different with the diesels having more shims and friction plates? Your saying that the gas doesn’t. The 6.7 250-350 have the same Powertrain and only differ in suspension slightly bigger diff housing and bigger bed blocks??

I need to drive one when I get a chance just because I'm curious. The first 2017 I drove was a regular cab 6.2L but it was a 350, so it had the other trans. Oddly it didn't start well or even run that smoothly and the body panels didn't line up well, but it was a super-early build. I actually thought about buying it for a work truck; it was an XLT so nicer than I needed for its purpose.
