    All, without warning last night, my transmission went out. I was in 4th gear driving normally and it felt like it dropped into neutral and a CEL came on. I have no forward gears, reverse shifts in very hard. DTC’s: P2701, P0731, P0734. There is about 6 inches of snow and ice and it is well below...

    Truck has 200k miles and never one issue or hint at an issue ever before with the trans. Now all of a sudden when I get past 40moh and it tries to shift it will lightly clunk, then flair in rpms and stay in 4th. It downshifts fine manually but won't upshift past 4th. Now here's where it gets...

    Can’t tell if my truck has trans tune or not. It does have some random EFI sotf tunes. Doesn’t go into 6th until about 67mph. Converter locks up real hard in 4th. Unlocks noticeably going to 5th, then locks hard again (can really feel the torque when it locks though lol) Also seems to lug in...

    I recently made the switch from a '08 F450 6.0 to a 2020 Ram 3500 tradesman crew cab DRW. My new truck has a 3.73 axle ratio with a 68RFE transmission. I tow 25,000lbs on a regular basis and had no idea a dually could be rated at only 20,000lbs MAX towing. Need to be able to tow my equipment...

    I just bought a 2015 Ram 2500 knowing it had transmission issues. It has efi live tuning and he said he had the local transmission shop do the tune. It's a small shop and I have no idea if they actually know what they are doing. Anyway, the transmission likes to go into neutral when in drive and...

    Recently deleted using ez Lynk and CTT. First thing: From what I’ve read CTT has very limited if any shift flare on their TCM tune but my likes to flare and I don’t like it... opinions? Second thing: The CTT TCM tune should have bumped my line pressure up to 225ish and now when I monitor both...

    I just changed my transmission fluid on my 2018 Ram 3500 with the 68RFE. After draining the old fluid and putting the pan back on, I added a gallon of fluid, and then started the engine. I let the truck idle for a few minutes in park then, to get the fluid circulating so I could check the level...

    Truck is a 2015 2500 outdoorsman. It has been deleted for about 6,000 miles and tuned by ecofreak custom tuning and have had zero issues with it. The stock 68 went out. I had been doing research on the g56 swap for a while now and it looked doable. Found a salvage yard that was selling a g56...

    Problem that happened to me while unhooked from my trailer followed by a solution.

    Greeting Cummins Community, I have been looking at removing the transmission bypass valve. On my recent trip of 15k lbs in the city, I saw about 200F on the transmission gauge. That is about 20 above what I want to see. Upon inspection, it appears there are flanges on both sides of the line. I...
