2017 ram 6.4 help

[Mattera350]

went to haul a frontier that weighs 3700# on a 2000# trailer about 15 min into the haul the truck starts to search for gears but couldn’t find a gear it liked on flat ground 45mph 5mpg about an hour into the haul check engine comes on and the red lightening bolts flashing trucks stuck in 4th gear limited to 50mpg rpm fluctuating 1800-2200 message on dash service electric throttle control. Any ideas what causes this light also why the truck struggles with such a light load since new it seems short on power

Did you ever get your transmission overheating issue sortied? When I had shift solenoid failure in my truck it was stuck in 4th. Before it locked itself into "limp mode" it was hunting gears, it would also not fully go into park. The shift indicator was show park but the truck would roll and if you touch the gas it would jump forward.

Unfortunately, the hunting for gears is just life with a 6.4 Hemi (great engine) and a 66rfe (crappy tranny). That being said there is obviously something wrong and the possibilities are endless. It may have something to do with the shifting or the shifting may just be more noticeable and worse with whatever else is going on. Get it to the dealer ASAP.... I'm assuming it's under warranty? These trucks are so high-tech that it's really hard to know without getting computer readouts and whatnot.

First off, punctuation is your friend. I’m 3 shots and 2 captain and cokes into the evening and your post hurt my brain with the run on sentence from hell.

Second, what gears are in the truck? And did you have it in tow haul mode?

I got the trans to run at 170* dealer called me n said pick ur truck up we will not fix it ur not welcomed back here since one guy said ur a fu**ing moron since I stated leds have nothing to do with the trans and the lift has nothing to do with the fuel tank issues. Long story short I told the guy they need to get mechanics not parts changers and that’s why I got that phone call. The trans I did a flush it cooled it down a bit already had the shift Solonoid and the valve body replaced

Gotta go with IRSmart on this one my friend.
Reading your posts is like getting yelled at by six people you don't know, all at once. LOL.
