Sonnax 6R80L-6R100-ZIP Transmission Valve Body Repair Kit

Application model key dimensions (A: length/B: diameter/C: diameter)

6R80 (after 2015)/6R100 A=. 645 ", B=. 629", C=. 511“

ZF6 Gen1 (including 6R80 2009-2014) A=. 645 ", B=. 629", C=. 495“

ZF6 Gen2 A=.804"，B=.629"，C=.511"

Material reinforcement design

The core components (such as accumulator piston and seal ring) are made of Sonnax special wear-resistant materials: the piston is made of high-strength engineering plastics, which is oil resistant and anti-aging; The sealing ring is made of nitrile rubber or fluororubber material, suitable for transmission oil (Ford XT-6-QSP/Merck SP), and is not easily hardened or deformed after long-term use.

（2） Key installation requirements

Valve body model identification

Before installation, it is necessary to confirm the compatibility of the valve body through the following 3 steps to avoid misuse:

Casting identification: The casting number for the upper valve body of 6R80 (after 2015) is 9FL3P-7A092-BA/FL3P-7A092-AA, and the lower valve body is FL3P-7A101-AA, without D2 Passage Eliminated;

Electromagnetic valve identification: The electromagnetic valve connector is made of transparent material, and the nozzle color is black/brown (ordinary electromagnetic valve) or gray (SSE electromagnetic valve), and the surface of the electromagnetic valve has flow level markings (1-5);

Pressure regulator identification: The pressure regulator sleeve has a dedicated groove (refer to product figure 4), and the size should be consistent with the specifications of 6R80/6R100 in the table.

Installation specifications

Torque requirements: The connecting bolts between the valve body and the gearbox housing have a torque of 8Nm (71 in lb), the metal oil pan bolts have a torque of 14Nm (10 ft lb), and the output shaft flange nuts have a torque of 60Nm (44 ft lb). A torque wrench is required to ensure accuracy;

Installation of solenoid valve: If the old solenoid valve is reused, it needs to be installed back to its original position (TCM has learned its flow characteristics) and cannot be confused; The new solenoid valve needs to correspond to the "nozzle color position" (e.g. brown nozzle corresponds to SSA/SSC/TCC solenoid valve);

Vacuum testing: After installation, the built-in test spring and end plug of the kit must be used for vacuum testing to check the sealing of the oil passage (qualification standard: stable vacuum degree, no obvious leakage), otherwise it may cause the fault to recur after maintenance.

Postoperative calibration

After the repair is completed, it is necessary to reset the adaptive learning value (KAM) of the transmission. It is recommended to use a Ford specific diagnostic tool to perform this;

Complete 6 cycles of light throttle up and down shifting (after the oil temperature reaches 80 ℃) to allow TCM to relearn shifting parameters and ensure shifting quality;

The transmission fluid needs to be filled with Ford original XT-6-QSP or Mercon SP specifications, with a full filling of 9.5 quarts (9 liters) and maintenance filling of 4.2 quarts (4 liters). The oil level should be checked after the temperature reaches 88 ℃ (190 ℉) and the thermal control valve opens.

Fault diagnosis and additional repair suggestions

（1） Typical faults and kit compatibility

The kit can specifically solve the following faults of 6R80/6R100. If the fault exceeds the scope, additional specialized components need to be purchased:

Additional suggestions on the ability to solve typical fault kits

Shift shock/jerking can be solved (replace accumulator piston, pressure regulator). If the fault still exists, check the clutch clearance (must comply with OE specification 0.2-0.4mm)

Shift delay/no reverse gear can be solved (replace end plugs, sealing rings, repair oil passage leaks). Check the transmission oil pump pressure (must comply with 10Nm pump bolt torque)

The fault code of solenoid valve (such as P0868 low pressure) can be solved by replacing the sealing ring and pressure regulator of the solenoid valve. Use an ohmmeter to check the resistance of the solenoid valve (SSA/SSB=5.5 Ω, SSE=18 Ω)

TCC slip/lock abnormality can be resolved (replace TCC related sealing rings, bypass clutch adjuster). Check the wear of the torque converter and replace it if necessary

（2） Key wear areas and testing

The technical manual accompanying the kit specifies in detail the wear areas of the valve body that need to be inspected in detail. It is recommended to verify through vacuum testing:

Lower valve body: main pressure regulator valve, clutch A/E control regulator valve, solenoid valve pressure regulator valve. If the vacuum degree is insufficient (such as below 50% of the standard value), an additional Sonnax oversize valve kit (such as 95740-46K main pressure valve kit) needs to be purchased;

Upper valve body: accumulator piston (sealing in inverted state needs to be tested), clutch B/D control valve. If the piston sinks more than 0.030 ", the reinforced piston needs to be replaced (the kit includes the basic version, and the high-strength version needs to be ordered separately).
