4R70W Shift Kit 1992, new and ready to install. Fits the 4R70W. Ships fast from the USA.
This listing is the valve-included version of Superior's AOD-E/4R70W shift correction package, the box marked KAOD-E-V. It starts at 1992 because that is the first year of Ford's electronic AODE, and the same kit carries forward into the 4R70W used in the F-150, Expedition, Mustang, Crown Victoria, Grand Marquis and Town Car. Pick this one if the valve body you are opening has real mileage on it: besides the springs, drill bits and ring set, it adds a new boost valve to replace the worn factory valve.
Line pressure in the AODE and 4R70W is set by the main pressure regulator, and the boost valve behind it is what raises that pressure when the EPC solenoid asks for more, under load and in Reverse. The boost valve rides in its own sleeve, and once the valve and bore wear, the EPC signal leaks off and the pressure rise never fully arrives. Sonnax ties boost valve wear to low Reverse boost, delayed or slipping Reverse, low line rise and a burnt Reverse clutch. A spring-only kit cannot restore that; a fresh valve can. The rest of the package recalibrates the accumulator and regulator circuits for shorter, firmer shifts, improves lube, and supplies Superior's two-piece Spiral Plus ring set to replace a factory snap ring that can sling off.
A pressure gauge is the honest test. If line pressure does not rise as it should when you load the engine or select Reverse, the regulator and boost circuit are suspect; Transmission Digest describes how a worn regulator bore bleeds EPC oil away and kills the line rise. Electrical faults have to be cleared first, though, because solenoid codes from a bad connector can mimic a hydraulic problem. Our Crown Victoria shift problem guide and Mustang shift problem guide walk through both checks.
Be clear on one point: no 1992 Ford left the factory with a 4R70W. The 4R70W arrived for 1993 in the Lincoln Mark VIII and spread from there; in 1992 the electronic four-speed was the AODE, offered first in the Lincoln Town Car. The 1992 in this listing is the start of the kit's coverage, and the same Superior package fits both units going forward. A 1992 vehicle with the electronic AODE is a fit; one with the older throttle-cable AOD is not, so check for a wiring connector on the case before ordering. Inside the range, separator plates and pressure regulators changed by year (the regulator design split at 1995-1996), so follow the year notes in the instructions. If you would rather have the standard kit without the valve, see the 4R70W shift kit for 1992-2005. Send your year and VIN if you want us to check, or browse the 4R70W collection.
Pull the valve body with the pan off, keep each valve and spring in order on a clean tray, and fit the new boost valve into its sleeve dry first to confirm it slides freely before oiling it. Inspect the main regulator bore; if it is badly worn, the kit cannot fully seal it. Drill only where the instructions say, for your year. If the unit has been slipping, rebuild it at the same time with a 4R70W banner rebuild kit, and on a 1996-1997 unit the 1996-1997 overhaul kit is the matching set of seals and gaskets. Refill with the fluid your owner guide lists and check it hot.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This is the KAOD-E-V version. It contains the same shift correction parts plus a new boost valve to replace the worn factory boost valve, which matters on high-mileage valve bodies with Reverse or line rise complaints.
No. In 1992 the electronic four-speed was the AODE. The 4R70W came for 1993 with the Lincoln Mark VIII. This Superior kit covers both units, so a 1992 AODE vehicle is a fit, but the older hydraulic AOD is not.
If the slip comes from a worn boost valve and low Reverse pressure, the new valve addresses that. If the Reverse clutch is already burnt, it has to be replaced as well.
The drill bits for the valve body and plate modifications come in the kit. You need a drill, basic hand tools, a torque wrench for the valve body bolts and a clean work surface.
A new filter and pan gasket at minimum. If the transmission slipped or the fluid is burnt, rebuild with a full kit of frictions, steels and bands so the new pressure calibration is not wasted on damaged parts.
