Transmission is best suited for heavier towing and some increase in horsepower. Valve identification for the upper valve body is in Figure 4, and Figure 5 identifies the lower-valve-body valve arrangements. The LEVEL 2-5R110 Transmission comes with deep pan, modified pump and modified clutch packs. You have two checkballs, two checkvalves and the location of the pump inlet nozzle. Figure 3 shows the valve-body small parts – not a lot going on here. A normally low solenoid will exhaust its related circuit when power is removed.įigure 2 shows a funnel-shaped object stuck to the spacer plate this is the pump inlet nozzle. A normally high solenoid will pressurize its related hydraulic circuit when power is removed. Its solenoids are all regulating types and therefore must be categorized as either normally high or normally low. You can also notice that just like its predecessor this unit has no on/off solenoids. In Figure 1 the solenoids are identified, and as you can see there are seven of them. Line pressure at wide-open-throttle (WOT) is 230 psi and only 10 psi higher in reverse at WOT for a spec of 240 psi.Īnytime a new transmission comes out we at ATSG usually like to start with the hydraulic control system, so we will start with the valve body in this issue. Line pressure for this unit is slightly unusual 90 psi is the spec in both drive and reverse at idle. The factory fluid is Mercon® LV, and dry capacity is 16.2 quarts for trucks equipped with diesel engines and 17.2 quarts for trucks equipped with gasoline engines. The 6R140W has a pretty gutsy initial take-off due to a 3.97 first-gear ratio. Depending on transmission temperature, it will allow converter-clutch operation from first gear on up through sixth gear. Unlike the 5R110W, which was also a six-speed – although, depending on transmission temperature, it would give you only five forward speeds – the 6R140W will provide all six speeds at any given time.
