It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system one primary filter for transmission sump, one for the fluid cooler return system. It was normally paired with the 4. Service fill is 6—8 quarts. Gear ratios were designed to maintain speed on long or high grades, without sacrificing highway efficiency. The solenoid pack is mounted directly to the valve body; its connector protrudes from a hole on the left side of the transmission.
The shafts, clutches, pump, torque converter, and other parts were also redesigned to handle the. All 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. Ram has been developed sophisticated transmissions through years and it is critical that you add the exact type of transmission fluid stipulated by your owner's manual typically in the back of the manual in a section titled Fluid Capacities. If you are having problems with the transmission in your 1500, such as clunky shifting or hesitation, check the fluid level first - it is amazing how many drivers pay thousands of dollars for transmission work when a half quart of transmission fluid would have fixed the problem. When adding transmission fluid to your 1500, be sure to add it slowly as the transmission fluid capacity is reached quickly and it is difficult to remove excess fluid if you overfill. The name refers to its design and Full Electronic control system. This article needs additional citations for.
The tapered side of the two tapered snap rings in the input clutch must face up. The 2C reaction plate has to go in first when rebuilding the 2C clutch, not the separator plate. Owners pointed to weak spots in the 2007-11 units, particularly the torque converter. Underdrive clutch clearance is not adjustable, but reverse clutch clearance is, via a selectable snap ring. They all use three planetary gearsets, three driving clutches, three holding clutches, and an overrunning clutch.
The Getrag six speed manual available on these trucks had a 5. The underdrive, overdrive, and reverse clutch assembly snap rings are not interchangeable between transmissions. If the transmission fluid level on your 1500 is low, you need to add fluid through the dipstick tube. Stumble accross this spreadsheet and thought it might be useful. Depending on type and size of internal cooler, length and inside diameter of cooler lines, or use of an auxiliary cooler, these capacities may vary.
A variation may be observed from vehicle to vehicle due to manufacturing tolerance and refill procedure. Refer to 19, Steering for proper fill and bleed procedures. . Under partial throttle, shifting into gears above third was delayed; and the system was likely to kick down under part throttle into fourth and fifth. Unsourced material may be challenged and removed. 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. During limp mode, the manual valve provides reverse, neutral, and fourth gear.
Before adding transmission fluid, make sure that your engine was running when you checked the fluid level. With the exception of an improved torque converter, it is physically the same as its predecessor. This video shows you how to add transmission fluid to your 2012 Ram 1500. The transmission-control is built into the powertrain computer. It used a computer that did not allow retrofits into earlier trucks. They do not use a 7 thrust bearing; the 11 bearing is in the input and reverse planetary assembly.
