The ’03 version on the left should not be used at all. The clutch spline length was shortened as well ( Figure 3). By 2004 the rear planet was updated to limit the pinion-gear pins from walking out. The sun-gear tooth count went from 42 to 55 in 2005.Ī new rear planet was also included in the ’05-up package as a precaution, due to earlier failures. Using the first-design rear planet with the ’05-up shell can cause interference. Although the overall length of the shell is different, the main area of concern is the back side of the shell.
Not only did the tooth count of the front sun gear change, but so did the shell ( Figure 2). Gas applications have six tabs and diesels have four tabs. The lube dam increased in diameter, and there are now two types. Along with the thrust washer increasing in diameter is the lube-dam change. The tooth count for the front ring gear and hub went from 78 to 101 in ’05. Planet-gear tooth count increased from 18 in 03-04 to -up. The forward drum changed slightly as well. The forward frictions were changed from 90 teeth to 76 teeth. 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.
