2013 Ram 2500 6.7. Turbo back 5 inch and anarchy tune as well as transmission tune. Bone stock except that. I installed everything Monday and have been driving it everyday. I haven't been hard on it at all. Waiting on the transmission to smooth out and relearn. Question is, it starts a slight shaking ( almost like a tire out of align, grabbing feeling) at around 1800 rpms. It's just before the transmission shifts gears. From 35 to 38 mph range. Then at 45, 55 , and just steady cruising around 75. I feel like it's the transmission, but may could be something in the motor tune. Transmission is still all over the place with shift smoothness and firmness. Great one time, then horrible the next. I've called Anarchy two days in a row. They haven't got back with me. It's very irritating to drive right now. Any ideas?

68RFE is a POS...What else it new? Fan boys will jump in here and tell you its your fault. The bottom line is the 68RFE is junk and everyone who is NOT BRAND LOYAL knows it. Get rid of it while it's still worth something. Save yourself the headache and get a Allison and Torqshift.

Maybe, but it was fine before the tune. I also just got rid of one with 230,000 miles on it that was original except for a rev max tcm. Never had an issue.

Yup. Sounds exactly like a 68RFE.. Hit or miss.... You can try reflashing the tune which will reset the CVI values. Then do the 50 mile drive to let it relearn.

Sounds to me like the trans tuning, specifically the converter lockup schedule. I'd check with whoever you got the tune from.
Bingo! Call your tuner and they'll get it straightened out. You also have to do a drive learn, so make sure you keep it under 30% throttle for 30-50 miles with no extended highway driving and make sure to shift up and down as much as possible to let it learn the CVI's. It will continue to learn for 500-800 miles but the CVI's will be established after 30-50 so you don't have to baby it. The 68's are a decent trans.

Does it do it in tow haul as well? Or if you manually shift it? How many miles do you have on it since the tune?

It does it any way you drive it, at those exact speeds. If you change manually and hold out until higher rpms, it will go away. Probably around 500 miles. I did the relearn the way your supposed to.

Im stupid. It just hit me why you responded that way. LoL. I guess it doesn't do it if you change manually. The problem is crossing at those speeds in the "normal gear". You can't feel it if accelerating. I'll try the tuner again Monday.
