5R55E Shift Kit 1994, new and ready to install. Fits the 5R55E. Ships fast from the USA.
A Ranger or Explorer with the 4R55E or 5R55E that thumps hard into Reverse after a long pause, will not back up at all, or keeps setting a converter clutch slip code after a fresh overhaul is a common sight in transmission shops. This new TransGo SK 44-55E shift kit is the valve body repair kit for that whole family, and besides firming up the forward shifts it carries two lesser-known fixes: a reverse engagement correction and a converter clutch exhaust correction. Both are explained below so you know exactly what you are getting for your truck.
These transmissions shift with a mix of clutches and bands, and the valve body decides how hard each one is applied. From the factory, shift apply pressure can be regulated down to about 40 psi even when line pressure is higher, so bands and the forward clutch slip through every shift and wear out early. The SK 44-55E raises that apply pressure with a new forward control spring and end plug, adds an EPC limit and converter relief assembly, and supplies a tapered orifice for the second band feed. That is the core of the kit, and it is what stops the hard-throttle 2-3 slip these trucks are known for.
Delayed, banging Reverse on this family usually traces to how fast the reverse circuit fills. TransGo's added procedure installs a gold retainer in a specified valve body cavity, requires that the .250 inch check ball in that circuit be present, and reduces one separator plate hole from its original .067 to .071 inch down to .046 to .052 inch. TransGo describes the result as a firm Reverse engagement like the older A4LD, with a smaller hole giving a softer feel. The procedure works on bonded plates as well.
Some trucks still set TCC slip or stuck-off codes after an overhaul with a new converter, even when the solenoid, pump and converter all check out. TransGo's fix drills a 1/16 inch exhaust hole under the TCC shift valve and plugs a plate passage with a bent wire supplied in the kit. It is worth doing on any unit that has had this complaint, but it only helps when the hard parts are in fact good.
Measure the solenoids before opening the valve body. TransGo lists 22 to 48 ohms for the shift solenoids, 9 to 16 ohms for TCC and 3.1 to 5.7 ohms for EPC, and the transmission temperature thermistor at about 28,400 ohms at 70 degrees F. A unit that always starts in third is in limp mode, which is an electrical issue. Our harsh or delayed shift diagnostic guide walks through those tests in order.
TransGo's product page lists the SK 44-55E for all 4R44E, 4R55E, 5R44E and 5R55E units from 1994 on, while its printed instructions say 1995-2010. That gap matters for a true 1994 truck. The Ranger Station's chart shows Rangers through 1994 with the older A4LD, and the electronic 4R44E and 4R55E starting in 1995. Both carry the letter T on the door-jamb sticker, so the code alone will not settle it. If your truck is a 1994, read the transmission tag or send us the year and VIN before ordering. This kit does not fit the 5R55W, 5R55S or 5R55N. More parts for these trucks are in the 5R55 collection.
Keep removed parts in order and follow every TransGo step, including the required .063 inch cross-drill. Torque the valve body only 72 to 92 inch-pounds from the center out. Set the second band so the output shaft just turns by hand both ways; a single-wrap overdrive band backs off two turns from snug and a double-wrap band three. Fill with Mercon V. If the reverse complaint came with burned bands or clutches, the unit needs more than a valve body job, and the 5R55E banner rebuild kit with bands covers the soft parts. For a converter clutch complaint, test or replace the solenoid with the 5R55E TCC solenoid set before drilling.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it has an electronic 4R44E or 4R55E. Ford Rangers through 1994 generally used the A4LD, which needs a different kit. Check the transmission tag or send us the year and VIN.
It fixes reverse complaints caused by the valve body and fill rate. If the reverse band or direct clutch is already burned, those parts must be replaced too, so check the fluid and pan for friction debris first.
No. It is an extra correction TransGo includes for trucks that keep setting converter clutch slip codes after an overhaul when the solenoid, pump and converter are known to be good.
No. TransGo recommends a new EPC solenoid because they wear out, but it is sold separately. Test yours against the 3.1 to 5.7 ohm specification.
Mercon V. Check the level with the transmission at operating temperature.
