About this product

This listing is a used, original sun gear shell for the Ford 5R110W TorqShift, sold for builders who already have the transmission apart and know which shell they need. The 5R110W went into Super Duty pickups and the Excursion with the 6.0L and 6.4L Power Stroke and the gas V8 and V10, and later into E-Series vans and motorhome chassis. The title does not name a model year, so read the fitment section before you order: this part changed during production, and the wrong generation will not work in your case.

What the sun shell does in a 5R110W

The sun shell sits behind the center support and links the clutch drums to the common sun gear of the front and rear planetary sets. Its rim lugs are driven or held by a clutch, and its splined center drives the sun gear. Whenever a gear needs the sun turning or stopped, the load passes through this stamping. It is a durable part on its own. It breaks when a clutch upstream slips, overheats and then grabs hard, sending a shock through the gear train that cracks the hub weld or rounds the lugs.

Three versions to know about

Since this listing has no year, compare it with your old part. Count the sun gear teeth, check the shell length, and look for the collar. If those three match, the shell fits.

Symptoms of a broken shell

How to confirm it before buying

Rule out the hydraulic side first. Our 5R110 shift solenoid guide explains which solenoid controls each clutch, so you can tell a stuck solenoid from a broken part. The 5R110 TorqShift service guide covers pan inspection and what the debris tells you. Once the unit is apart, a shell is easy to judge: look for cracks at the hub, flattened lugs and worn splines where the sun gear sits.

Fitment

This part fits a 5R110W only, and only the matching design generation. If you know your year, the dated listings are simpler: the 2003 5R110W sun shell for early units and the 2008-2019 5R110W sun shell for late ones. Units rebuilt earlier often carry update parts that do not match the truck's year, so go by what is in the case. If you are unsure, send us the year, the VIN and a photo of your old shell and we will help confirm the match. All TorqShift parts are on the 5R110W parts page.

5R110W Sun Shell: common questions

Which years does this sun shell fit?

The listing has no year, so match it to your old part. Count the sun gear teeth (42 on 2003-2004, 55 from 2005), compare the shell length, and check for a collar, which late 2008-up shells do not have.

Can I put a 2005-up shell in a 2003-2004 transmission?

Not as a straight swap. The sun gear tooth count changed, and the later shell can interfere with a first-design rear planet. Ford released the 2005 parts as a package because those pieces have to be changed together.

What usually breaks a 5R110W sun shell?

A clutch that slipped and overheated, then grabbed. The shock load cracks the hub or rounds the lugs. Fix the clutch and its hydraulic cause, or the new shell will fail the same way.

What fluid does the 5R110W use after the repair?

These transmissions were factory filled with Mercon SP, and Ford now services them with Mercon LV. Check your owner manual and replace the filter and cooler after any repair that left metal in the pan.

Is a used shell reliable?

It is a stamped steel part with no friction surfaces, so a clean take-out with good lugs, a solid hub and tight splines works like new. Inspect it before installing it.
