Check line pressure with gauge. Is the pressure gauge smooth? If yes, the pressure regulator system is in good shape and no air is entering the system. If no, inspect for cracked filer or poor seal. A cross leak or place for air to be sucked into system. 2. Is the noise there sitting still and in gear? If yes, Inspect converter and converter hub bearing and pump. If no, inspect transmission gear train and drive train. This bulletin does not apply. 3. Is the noise there whenever the engine is running? If yes, Check converter hub bearing and pump. If no this bulletin does not apply. Ford 6R140 transmission has no pump bushing. Ford now uses a bearing like some of the Mercedes transmission. This bearing is also failing with low miles as seen in figure 1. Inspect the bearing for pit- ting and wear marks. At the time of this bulletin the bearing is only sold as part of the complete pump.

Lineartronic CVT Gen 1Secondary Pressure and Transfer ClutchPressure TestingSubaruApril, 2014

Technical Bulletin #1604

Lineartronic CVT Gen 1Secondary Pressure and Transfer Clutch Pressure TestingWarning: You need a 1000 PSI gauge and hose to test secondary pressure. I would suggest using a transducer for added safety.

To check secondary pulley pressure (line pressure) we are going to need to remove the pressure plug on the passenger’s side of the transmission shown in figure 1. The fitting threads on the secondary pressure plug are 14mm x 1.5mm. The pressure is high and we need a 1000 PSI gauge set. I would recommend the use of a transducer or the Subaru testing equipment.

The Subaru part numbers for testing equipment:

#1604With the transducer or gauge hooked up check and record pressure readings at idle in park, reverse, neutral and drive. Then test reverse at stall and drive at stall. In figure 2 is the chart for line pressure specification for reference. If line pressure is low some of the area’s to look at would be a plugged filter, bad pump and leaks in the secondary pulley circuit.

Transfer clutch pressureIn figure 3 is the transfer clutch pressure port. Install gauge or transducer in port. With scan tool enter FWD mode and test should show 0 psi on tap in all ranges. If pressure is shown, there may be a prob-lem with transfer clutch control solenoid or valve.

Hondas with External MLPS SwitchRough/Delayed Engagements, Range Indicator ProblemsHondaApril, 2014

Technical Bulletin #1605

Hondas with External MLPS SwitchRough/Delayed Engagement, Range Indicator ProblemsAfter overhaul you may experience delayed or rough engagements into forward or reverse. Gear range indicator light problems may also occur.

The cause of these complaints is a loose fit between the manual lever selector shaft into the MLPS switch. This happens when the case cover is being installed. The technician sees that the roll pin on the selector shaft is not lined up with the key way in the case cover. A pair of pliers is used to rotate the shaft into position. Twisting the shaft with pliers or vise grips will collapse the shaft causing a loose fit. Simply spread the shaft open to obtain a good fit between the shaft and MLPS switch.

TH400Diagnosing Late Shifts or No Kick Down,Detent Solenoid ProblemsGMApril, 2014

Technical Bulletin #1606

TH400Diagnosing Late Shifts or No Kick DownAn oldie but a goodie that has plagued many technicians. When a 400 has late shifts, it either has no vacuum to the modulator or the detent solenoid is active (solenoid is open or leaks). If there’s no kick down it’s usally an innactive detent solenoid (solenoid stuck closed or no current). A quick way to find out what’s at fault is with a pressure gauge.

Late ShiftsMeasure the line pressure in neutral and drive. The pressure readings should be the same in both ranges 55-80lbs. If the line pressure jumps to 95-105 in drive and drops back to 55-80lbs when the lever is placed back in neutral, the detent solenoid circuit is active and is the cause of the late shifts. If the line pressure is high in neutral and in drive, it’s a vacuum flow or modulator related problem.

Causes of Late Shifts-Active Solenoid Circuit (High Pressure in Drive Only)1-The solenoid is stuck open2-Solenoid bolts are loose3-Has a gasket installed on with an “open winding solenoid”4-Seperator plate feed orifice is missing,covered or plugged5-Detent regulator valve stuck open6-The solenoid gasket is missing or leaking on a “closed winding soleonid”7-Has battery current to the solenoid with accelerator pedal in closed throttle position

No Kick-Down and Early WOT ShiftsAttach a remote starter switch to the battery positive post and to the soleonid case connector. Line pressure should be 55-80lbs in nuetral. Place the lever in the drive position and energize the solenoid, check the line pressure. If there’s no increase in line pressure while in drive with solenoid energized see “inactive solenoid” causes.

#1606Inactive Solenoid Circuit Causes: No Kick Down and Early WOT Shifts1-The solenoid is stuck closed2-The seperator plate feed orifice is too big3-Detent regulator valve is stuck closed

If there’s a line pressure increase in drive with remote stater switch, repeat the test using the vehicles electrical system to energize the solenoid. When using the vehicle electrical system, if there still is no pressure increase then there is a blown fuse, bad switch or a resistance problem. The late GM trucks from 1987 on utilize a TPS triggered relay that commonly fails.

Open winding solenoids have a rubber gasket molded into the mounting flange. If the metal gasket is installed, it will create a leak in the circuit and cause late shifts.

Closed winding solenoids require a gasket. If the gasket is left out it will cause late shifts.

Closed Winding SolenoidOpen Winding Solenoid

If you have one that will not kick down, has line pressure increase with solenoid enegrized. Remove the gear and valve from the governor. Blow air through the gear end of valve, air must exit at balance port.

#1606When working on any GM transmission. High line pressure from a pressure regulator problem will only cause rough shifts, never late shifts.

The 400 detent solenoid is tied into the modulator circuit. A leak in the solenoid circuit will cause a pressure boost created by the modulator circuit in drive only and late shifts.

PCSV-A: When the oil pressure is required for OD clutch or Low & reverse brake, this solenoid valve must be off.

PCSV-B: When the oil pressure is required for 2nd brake or Reverse clutch, this solenoid valve must be off. If the manual valve ‘R’ position is selected, the pressure will be applied to the reverse clutch. That is the reason why the reverse clutch is not engaged in 2nd and 4th gear (PCSV-B off condition)

PCSV-C: When this solenoid valve is off, UD clutch will be engaged.

PCSV-D: When this solenoid is off, the damper clutch is released.

SCSV (On/Off): When this solenoid valve is off, LR brake pressure is released and the OD clutch pres-sure is applied. That is the reason why the 3rd gear failsafe (mechanically failed 3rd gear condition) is possible when the all solenoid valves are off including this solenoid valve.

VFS Solenoid Valve: Changes the line pressure according to throttle open angle (engine load) and shift ranges.

#1608The C clutch drum shaft bushings not only provide support for the shaft and drum. The bushings are also critical seals for the reverse hydraulic circuit. Most often the bushings may have an appearance of “in good condition”. You should always place the C drum shaft over the input planet shaft and check the bushing fit one end at a time.

If the bushings are worn reverse oil will be dumped into the lube circuit and pan. Replacment bushings are availible. The o-rings and teflon sealing rings are equally important as well.
