Along with the appearance difference between the ’03-04 on the left and the ’05-up on the right is the forward-clutch spline count. To start with, the front planetary components changed tooth counts and diameters ( Figure 1). In 2005, the gloves came off and a lot of stuff got changed, similar to the OD section thing in 2007. So much for the front end of the transmission what about the back end, behind the center support? All previous-model components have been deleted. All four packages cost several hundred dollars. Last, non-PTO applications have just a sensor ring bolted to the planet, whereas PTO applications have a drive gear as well. ![]() This change in tooth count resulted in a slight ratio difference. The planet, sun-gear and ring tooth counts were changed as follows: What makes this worse is that beyond the OWC and coast drum is the planetary gear set. The stamping denotes only which OWC is included. Functionally, there is not much difference.Īlthough the coast-clutch drum is stamped “gas” or “diesel,” they are the same. The gas version has two missing teeth, whereas the diesel has a full set. To start with, the OD OWC was split into two versions, one gas and one diesel. This change made the previous one look like child’s play. The pace really picked up at the front end, in 2007, when Ford released four new packages, which depended upon whether the engine was gas or diesel and whether the transmission had PTO. Gas or diesel applications didn’t matter. The package included the OWC, coast-clutch drum and OD sun gear. This change triggered the first OD-package launch, due to the wider OWC and repositioning of the snap-ring groove in the coast-clutch drum. The fix was to increase the width of the OWC by about 0.040 inch. Initially, there was a problem with the overdrive one-way clutch (OWC), which is a mechanical diode. ![]() ![]() It’s hard to limit the overall repair cost when the part components of the repair enter the stratosphere.Ĭertain upgrades like the pump and valve body were not much of an issue, unlike what happened regarding the coast-clutch assembly. These OEM modifications have rendered cost containment nonexistent. Some of the item upgrades had been limited to the item itself, whereas others resulted in rather expensive and heavy packages. Beginning with the launch of the 5R110W in 2003, the number of tweaks has been unending.
