AODE Shift Kit 1991-2013, new and ready to install. Fits the AODE. Ships fast from the USA.
The AODE was Ford's first electronically controlled overdrive automatic, the computer-shifted successor to the old hydraulic AOD, and it arrived behind the 4.6L in the early-1990s Crown Victoria, Grand Marquis and Town Car. This TransGo shift kit is the valve body repair for that unit. TransGo builds a single kit for the AODE and everything that grew out of it, the 4R70W and 4R75W included, and covers it from 1991 on; that is where the 1991-2013 range in the title comes from. If your early Panther car flares between gears, bangs on a downshift, or just had its overdrive band replaced, this page is for you.
The AODE kept the AOD's gearset, with a 2.40 first gear and a 0.67 overdrive, but replaced the throttle valve cable with solenoids. Two shift solenoids choose the gear and the EPC solenoid sets line pressure for every shift. After a couple hundred thousand miles the valve body bores are worn, the solenoid regulator valve sticks or leaks, and the accumulators let each shift drag on. The kit answers that with a no-stick solenoid regulator valve, a drop-in pressure regulator valve, firmer accumulator springs, a 3rd accumulator plate saver for cracked separator plates, an EPC relief system and better forward clutch sealing rings, according to TransGo's own parts list.
Before you pull the valve body, scan for solenoid circuit codes and check the fluid. Early AODE units use the white soft-wired internal harness, and a chafed wire or a bad solenoid can mimic a valve body fault. Vacuum testing the solenoid regulator and pressure regulator bores is the shop method for proving wear. Our Crown Victoria shift problem guide walks through the Panther-car symptoms, and the shift solenoid testing guide covers the electrical checks.
The kit fits the AODE as one TransGo application from 1991 on. AODE units use a different gear ratio set and the early soft-wired harness, and they do not share solenoids with 1998-later 4R70W units, but the valve body kit is common to the family. The instructions branch by year and separator plate, so lay your old plate next to the sheet before modifying anything. Not sure if you have an AODE or an early 4R70W? Both look alike from under the car; send your year and VIN, or browse the AODE and 4R70W parts collection.
The kit installs from under the car with the transmission in place. Drain the pan, unplug the harness, and lift out the valve body on a clean bench, laying every valve and spring out in order before swapping parts. Inspect the bores; a scored pressure regulator bore needs more than a kit. If the band or direct clutch is already burned, this kit belongs inside an overhaul, not in place of one, so pair it with a rebuild kit such as the 4R70W master rebuild kit (check that the friction count matches your AODE) and inspect the AODE clutch drum while it is apart. Refill with Mercon V or the fluid your owner guide calls for, check level hot, and reset adaptive memory before the road test.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
TransGo covers the AODE, 4R70W/E and 4R75W/E with one shift kit from 1991 on. The instructions branch by year and separator plate, so an AODE gets its own steps even though the parts in the box are shared.
The AOD is fully hydraulic and uses a throttle valve cable from the throttle body. The AODE has no TV cable and a wiring connector on the case for its solenoids. If there is no cable and the computer controls shifting, you have the electronic unit.
It addresses the causes TransGo lists for 4th and overdrive band failure: weak solenoid regulator output, low line pressure and slow accumulator action. It cannot fix a band that is already burnt, so replace the band and drum if they are damaged.
Basic hand tools, a torque wrench for the valve body bolts, and a drill if your year calls for any separator plate holes to be opened. Follow the sheet for drill sizes; do not guess.
Use the fluid your owner guide specifies, which for these years is a Mercon-type ATF. Check the level hot in Park after the road test.
