Some days I have to get into the gas hard to get it to shift and other days it runs normal. What sucks about it is, when I'm in my neighborhood or say a school zone and have to do 20MPH, it won't shift! So here I am cruising at 3000RPM unless I romp on it to make it shift and that's not prudent in a school zone. Also, if I get a chance like at a red light, I can shut off the motor and restart and it runs normal again. Plus, as I said, there are days when it simply runs normal with no problems. Then there are sluggish days also where it just doesn't seem to get up to speed without really getting in it. Now, I do like the feeling of it when it acts up? like when I have to get on it to shift. That's when I really notice those 3.56 gears in it.

I can romp on it at take off and it'll jump up and go! Kinda scared to really get on it when it does this as I'm afraid I'll twist the driveshaft or an axle! lol Plus it hits each gear so hard that, if the tires weren't so big, they'd probably bark each time.Īnyway, I guess replacing both sensors isn't on my long list of honey do's for the D. LCATION MOPAR DODGE RAM PRESSURE SENSOR 545RFE TRANSMISSION PLUS I've been working both jobs a lot and with stupid Daylight Saving Time kicked in, there's not enough daylight left after my part time job. But at least I can get the parts ordered and have them waiting.The torque converter locked up in every forward gear except first, based on temperature, gear, tow/haul mode, and exhaust brake activation. It used a computer that did not allow retrofits into earlier trucks. Owners pointed to weak spots in the 2007-11 units, particularly the torque converter. Partly for that reason, in 2012, when Ram started selling a higher-output Cummins diesel truck (with 800 lb-ft of torque), they beefed up the torque converter and modified the shift algorithms for durability. Service notes: 66RFE and 68RFE automatic transmissions The 2012 66RFE and 68RFE had a wider overall gear range than the 545RFE/65RFE they can be identified with a label on the transmission case that shows the part number and build sequence (also stamped into the case, below the label). The 66 and 68 have one set of splines on the overdrive shaft the 545/65 has two. The 66RFE resembles the 545RFE from the outside, but shares its extension housing and output shaft with the 68RFE. The 66RFE has its torque converter recessed inside the case, while it sticks out of the 68RFE.Īll three transmissions, as used in 2012 and onwards, have a single-piece case, two-stage pump (which shuts the secondary side at higher speeds, for efficiency), and similar valve bodies. They all use three planetary gearsets, three driving clutches, three holding clutches, and an overrunning clutch. LCATION MOPAR DODGE RAM PRESSURE SENSOR 545RFE TRANSMISSION PLUS.
