Exclamation Revs and Slams + more..

I am in need of some help with diagnosing a problem here.

I was running a street tune from quicktrick and noticed my trans was shifting strange. I returned the truck to stock and the symptoms/problems have gotten far worse.

Basically the truck is slow to react when moving from park to reverse or drive. When it finally does move into gear it is rather firm. Sort of like the truck lurches forward or back. Second problem is the shifting from 2nd to 3rd. It will shift normal from 1-2 but going from 2-3 it will rev up(a lot if I dont let off the throttle) and slam into gear. It is pretty damn annoying that this shows up 23 days out of warranty, but I need my truck for work come the 28th(starting a new job) so any help would be greatly appreciated.

Fluid is a good color, smells ok, and the level is fine. No dtc codes or lights thrown.

Well here is an update. Driving down the highway, truck felt like it was slipping/loosing power. Was taking quite substantial throttle to maintain 100kph. Few seconds later I seen the trans temp was at 180, around 30-45 sec later the truck seemed to slip into neutral. I could rev it, but no movement forward. Pulled off to the side of the road and the trans temp was at 210. Smoke coming from under the truck and a light metallic rattle coming from the transmission hump.

After shut down and the smoke cleared, I looked under the truck and there is about 1 liter of fluid on the transfer case and cross member. Started it back up, checked the fluid which was still full, but there was a slight gray tint to what used to be nice and pink. As I waited 1.5 hours for a tow truck, the trans cooled off, so I figured I would try it. Very hard to get into drive, gear selector felt wrong. Drive felt like neutral etc. Very slow to engage drive/reverse, could rev the motor and the truck would creep or suddenly lurch ahead or backwards. So no 1,2,3 or drive or reverse.

So did you get it towed somewhere or did you limp it back home? Just curious how many miles are on the truck and how many of those miles were tuned? When was the last time your tranny fluid was changed? What does the bypass filter look like and when was the last time it was changed? When I pull mine, it has a slight gray tint to it, but it shouldn't be overly dirty. Your signature shows you have been running IDP tunes; how recent was the switch to Vivian's tunes and why did you change?

It obviously sounds like the torque converter has gone south on you, particularly with the sounds and symptoms you describe. More information might confirm or dispute that suggestion.

Thanks for the reply evil, bit as of right now I no longer have the problem. Traded in my f250 for a 2011 Dodge ram 2500 with the 6.7 and a 6speed manual No plans for a tuner or exhaust until warranty is up in 5 years, so in theory I shouldn't have to worry about a trans anytime soon.

Well I'm glad you were able to get another truck that will serve your needs. Congrats on the Dodge and I hope you still decide to hang around.

Well I have had the dodge 2 days now. It is kind of hard to compare the 6.7 cummins to the 6.0. Completely different technology. Cummins is crazy quiet. The mechanic that helped me put in my slip tank and tool box made a comment about it, because he thought it was a gas motor. The clutch is a bit stiff, but maybe I need some time to get used to a manual again. It will chatter/clunk a bit but nothing too bad. The ride is smoother than my 6.0 was before I lifted it. The new interior has come a long way to what it was even in 2009(bro has an 09 2500). Better quality plastics and more attention to keeping wind/motor/road noise out of the cab. I would put the "long horn" edition of the ram as more than equal to the KR or harley editions of the fords. You cant get a long horn with a manual so no dice there for me.

Main thing I noticed is the cummins get roughly the same mileage as my 6.0. Granted the truck has 202km on it now and after a break in I am sure it will go up a bit.
