4L80E Planetary Damage, Pump InterchangeGMOctober, 2013

Technical Bulletin #1117A

4L80EPlanetary Damage, Pump InterchangeAn update to the pump cover occurred for 2004-2006 model years on all 4L80E/85E applications. Thepump cover part number was changed to accommodate interim case changes that occurred. The fol-lowing part numbers for the pump cover based on model year.

This is a simple plug kit. Remove cup plug, install the 1 slug. Important: Do not bury the slug all theway down into the pump. When tapping the slug in, drive it in .355 below the pump surface. Installthe new cup plug. If a kit is not available from your parts supplier you can make your own. The size ofthis slug is 1 long and .247 (1 x .247) in diameter, the cup plug is .344.

CD4E Harsh 1-2 Shift or Erratic ShiftsFord October, 2013

Technical Bulletin #1561

CD4EHarsh 1-2 Shift or Erratic ShiftsIf you experience a harsh 1-2 shift after rebuild check the assembly of the 2/4 accumulator piston. It islocated in the accumulator section of the valve body. The correct assembly is shown in figure 1.

If by mistake it was assumed that all the accumulators install into the valve body in the same direction,

it may be possible that the 2/4 accumulator piston was misassembled as shown in figure 2.

Special thanks to Ratio Tek for the valve body pictures.

#1562In gure 2 are the di erent names for the solenoids, Ohms values and func on of the solenoids.

When we have a are or bump on a shi we are able to make an adjustment to one clutch at a me.

Before any adjustments are made some things have to be checked rst. Valve body condi on of Sole -noid Modula on valves, Lock up Control valves, Pressure Regulator and Secondary Regulator valvesneed to be checked for wear. Also the solenoids need to be rebuilt or con rm that the amature in thesolenoid is not s cking when hot (#1 problem).

Make sure all the latest updates to the so ware are installed. The transmission adapts and relearnsprocedure needs to be done along with a long test drive. If the relearn is not done properly you willmake more adjustment then necessary.

#1562Use the Clutch Apply chart ( gure 3) and Solenoid Firing chart ( gure 4) to learn what clutch needsadjusted.

One note on the solenoid apply chart remember that when the solenoid is o the clutch is applied.

Make adjustments half a turn to one turn at a me. Turn in the adjuster IN to slow the shi down(smooth/slow apply rate). Turn the adjuster OUT to speed up the apply rate of the clutch ( rmershi ).

6F35Leaks Out of the Dipstick 2009 Ford Escape and Mercury Mariner October, 2013


6F35Leaks Out of the DipstickSome 2009 Escape and Mariner vehicles equipped with 6F35 automatic transmissions and built on orbefore 10/29/2008 may exhibit a loss of transmission fluid from the dipstick tube area. This may bedue to transmission being overfilled. A new transmission dipstick and filler tube kit is now availablethrough Ford with added minimum and maximum fluid level lines to easily determine proper fluid

level and with a revised vent system on the filler tube.

Ford Part #AL8Z-7A020-A for the updated dipstick and tube.

6L80E Neutrals on Take Off, Checkball Locations2009 GMC YukonOctober, 2013


6L80ECheck Ball LocationsWe have been made aware of a problem with the plastic #1 check ball eroding from .250 to .180 andgetting stuck in the plate. The #1 ball is in play in Drive, from 1st - 6th gears.

#1 Drive 1-6/Drive Braking:

Located in the upper control valve body, this ball shuttle valve style check ball allows drive brakingfluid, in a Drive 1st gear engine braking condition, to enter the 2-6 clutch/1234 clutch feed fluid circuitto apply the 1-2-3-4 clutch.

#2 Solenoid 1/Reverse:Located in the upper control valve body, this ball shuttle valve style check ball is seated against thereverse fluid passage while the transmission is operating in Park, Neutral and Drive 1st (Engine Brak-ing). With the ball check valve in this position, solenoid 1 fluid enters the CSV2 enable fluid circuit toapply the clutch select valve 2. When the transmission is operating in Reverse, the ball check valveseats against the solenoid 1 fluid passage to allow reverse fluid to enter the CSV2 enable fluid circuitand hold the clutch select valve 2 in the applied position.

#3 Solenoid 2/4-5-6 Clutch:Located in the upper control valve body, this ball shuttle valve style check ball is seated against the456 clutch passage while the transmission is operating in Park, Reverse, Neutral, Drive 1st, 2nd and3rd gear ranges. With the ball check valve in this position, solenoid 2 fluid enters the CSV3 enable fluidcircuit to apply the clutch select valve 3. When the transmission is operating in Drive 4th, 5th or 6thgear ranges, the ball check valve seats against the solenoid 2 fluid passage to allow 456 clutch fluid toenter the CSV3 enable fluid circuit and hold the clutch select valve 2 in the applied position.

#4 PS5/4-5-6 Clutch:Located in the upper control valve body, this ball shuttle valve style check ball is seated against the456 clutch passage by PS5 fluid while the transmission is operating in Drive 1st, 2nd and 3rd gear rang-es. With the ball check valve in this position, PS5 fluid enters the SSV2 latch fluid circuit to hold theclutch select valve 2 in the released position. When the transmission is operating in Drive 4th, 5th or6th gear ranges, 456 clutch fluid pressure seats the ball check valve against the PS5 fluid passage to al-low 456 clutch fluid to enter the CSV2 latch fluid circuit to hold the clutch select valve 2 in the releasedposition.

#1564#5 Drive 1-6/3-5 Reverse Supply:Located in the upper control valve body, this ball shuttle valve style check ball is seated against theDrive 1-6 fluid passage by 35 reverse feed fluid while the transmission is operating in Reverse. Withthe ball check valve in this position, 35 reverse feed fluid enters the 35 reverse supply circuit and is

routed to the #7 ball check valve. When the transmission is operating in Drive 1st, 2nd, 3rd, 4th, 5th or6th gear ranges, Drive 1-6 clutch fluid pressure seats the ball check valve against the 35 reverse feedpassage to allow Drive 1-6 clutch fluid to enter the 35 reverse supply fluid circuit.

#6 2-6 Clutch/1-2-3-4 Clutch Feed:Located in the upper control valve body, this one way orifice control style check ball is used to dif-ferentiate the flow rate of fluid between applying and releasing the 1-2-3-4 clutch. 26 clutch/1234clutch feed fluid pressure opens the ball check valve while the transmission is operating in Drive 1st(engine braking), 1st, 2nd, 3rd, 4th, 5th or 6th gear ranges. With the ball check valve in this position,26 clutch/1234 clutch feed fluid flows freely into the 1234 clutch feed fluid passage. When Park, Re-verse or Neutral gear is selected after the transmission was operating in Drive, exhausting 1234 clutchfeed fluid seats the ball check valve and fluid is forced through orifice #32. This allows for a controlledexhaust of 1234 clutch feed fluid.

#7 3-5 Reverse Supply/3-5 Reverse Feed:Located in the upper control valve body, this one way orifice control style check ball is used to differ-entiate the flow rate of fluid between applying and releasing the 3-5 reverse clutch. 35 reverse supplyfluid pressure seats the ball check valve against the 35 reverse feed passage while the transmissionis operating in Reverse, Drive 1st, 2nd, 3rd, 4th, 5th or 6 gear ranges. With the ball check valve in thisposition, 35 reverse supply fluid is forced through orifice #25 before entering the 35 reverse feed fluidpassage. The orifice helps control the apply rate of the 3-5 clutch when the transmission shifts intoReverse, 3rd and 5th gears. When Park or Neutral gear is selected after the transmission was operat-ing in Drive, or Reverse, exhausting 35 reverse feed fluid unseats the ball check valve. This allows for afaster exhaust of 35 reverse feed fluid and a quick release of the 3-5 reverse clutch.
