Shift, EPC and TCC solenoids plus filter and pan gasket for the 2005-2008 Ford 4R70W and 4R75W with the 14-bolt pan. Replaces 76919 and 76420.
Crown Victoria, Grand Marquis and Town Car owners, along with F-150 drivers, end up here for the same reasons: the transmission takes off in second, flares or bangs between gears, or never locks the converter on the highway. This kit, manufacturer part CXT-TRS01701, covers the 2005-2008 Ford 4R70W and 4R75W with the 14-bolt oil pan and puts every electrical part on the valve body in one package - the shift solenoid pack, the EPC solenoid, the TCC solenoid - with a filter and pan gasket so the service is finished in one pan drop.
The PCM never moves a shift valve directly. It fires the shift solenoids, and their on/off combination routes oil to the valves that select each gear. On this family the pattern is SS1 on and SS2 off for 1st, both off for 2nd, SS1 off and SS2 on for 3rd and both on for 4th, per Sonnax's application chart. That is why a dead SS1 circuit commonly leaves the car starting in 2nd. Line pressure is handled by the EPC, a variable force solenoid that raises pressure as its current drops, and the TCC solenoid controls converter lockup. On a police-package or livery Panther that idles, accelerates and brakes all day, heat breaks these parts down faster than mileage alone suggests.
Start at the case connector. Sonnax's booklet gives the pin layout for the 1998-2008 connector and the target readings - 20-30 ohms for each shift solenoid, 10-16 for the TCC, 2-5 for the EPC. Wiggle the harness while reading; an intermittent value is a wiring fault. Transmission Digest has documented a 4R70W that started in a higher gear with solenoid codes after an overhaul, caused by terminals pushed back in a poor-quality case connector, so inspect the pins closely. If the electrical tests pass and the complaint is a slip under throttle, it is likely hydraulic, which our Crown Victoria shift problems guide and EPC symptoms guide walk through.
Fits 2005-2008 4R70W and 4R75W transmissions with the 14-bolt pan; Ford's later documents may label the same units 4R70E or 4R75E. Pan bolt count is the fastest check, since earlier transmissions use a different pan and filter and this filter will not seat on them. The kit replaces kit numbers 76919, 76420, 76921, 76923 and 46118 and Ford F6AZ-7G383-AA, F7AZ-7G484-AA and F5AZ-7G136-A. Match one of those numbers to your existing parts, or send us your year and VIN. Model years outside this range are on the 4R70W and 4R75W page.
Lift the car, drain and drop the pan, and remove the filter. With the valve body exposed, unplug and unbolt the solenoids, fit new O-rings soaked in ATF, and install the new solenoids without forcing them into their bores. Inspect the internal harness while it is accessible; if it is cracked, add the matching solenoid kit with wire harness. If you find the valve body worn or damaged, a 2004-2011 4R75W valve body is the next step. Fit the new filter and gasket, tighten the pan bolts evenly in a crisscross pattern, and refill with MERCON V. Clear codes, then road test through all four gears and confirm lockup at cruise.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It often does when the cause is shift solenoid A or its circuit. Ohm the solenoid at the case connector first; if the reading is out of the 20-30 ohm range, the kit addresses it. If the solenoid reads good, check the harness and connector.
Count the pan bolts. This kit and its filter are for the 14-bolt pan used on 2005-2008 units. Earlier transmissions use a different pan and filter.
Kit numbers 76919, 76420, 76921, 76923 and 46118, and Ford F6AZ-7G383-AA, F7AZ-7G484-AA and F5AZ-7G136-A. The manufacturer part number is CXT-TRS01701.
MERCON V. Ford's quick reference chart lists it for the 4R70W and 4R75W family. Check the level hot after the road test.
Replace the internal harness if it is brittle, and inspect the valve body for wear. If the transmission still slips under load after the electrical repair, the cause is hydraulic or friction wear, not the solenoids.
