DTC will set if one of the following conditions occurs for 5 seconds: *Control module commands solenoid on and voltage remains high (battery voltage) *Control module commands solenoid off and voltage remains low (zero volts)" But I wouldn't be surprised if there are other issues that can throw this code. 35386A 4L60E 4L80E Transmission (MLP) manual lever position switch 1995-2003. E: ignition power feed from TCM to solenoids . Sometimes these plugs may be stuck, so wiggle them a little to get them free. There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. Simply repeat this process for the other solenoid to verify both are working or not. Like it or not, modifications will always be a part of this business. 35382B 700R4 Torque converter clutch signal switch 1982-92. Central Oklahoma. CPT 4l60e participates in the Amazon Associates program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, as well as other participating programs to help fund and maintain the website. This eliminates slip and prevents excess heat during high-load conditions. T: tcc solenoid (on/off in pump) U: tcc pwm solenoid (valve body) TCC lock-up solenoid is normally only energized in 4th gear, if the transmission temperature is above 250F it will energize it in 2nd and 3rd as well. No machining required. F]:(6I5j4 Next, take your test leads and connect them to the backside of the solenoid where the electrical prongs are. Transmission builders are no strangers to modification. While 4l60e shift solenoids do go bad, its not a common occurrence. While some people call them the 1-2 Shift and 2-3 Shift solenoids, that is actually confusing and therefore many others refer to them simply as solenoids A and B.

Helps cure: TCC apply concerns; Overheated converter; Loss of lube oil; TCC Solenoid Snout Kit 77942-02K. D: pressure control solenoid low . The TCC lining also was changed, from paper to a high-carbon content lining to stand up to the extra friction and heat generated during PWM operation. Voltage drop testing is also accurate but you also need to put your component under load. Has PWM stamped cast in pump. This is enough for extra holding power while avoiding the consequences of full line pressure to the TCC piston. There is a common modification for the 4L60-E TCC circuit that causes multiple problems, one of which is TCC friction delamination. trailer

It is Digikey MSP6907-ND for $114. However if they burn out the computer should generate a DTC code. This blocking modification has been embraced by some builders of high performance or heavy towing units, even without a trouble code to conquer. Since the apply pressures are capped in this manner, the pressure limiter can be used with friction linings designed for on/off, PWM or EC3 with great success. C: pressure control solenoid high . TGM-HR GM Harness Connector Removal Tool for 4L30E, 4L60E, 4L80E, 4T40E. This adaptive control strategy can provide nuggets of diagnostic gold: as the regulator bore wears, the duty cycle required to keep slip in the appropriate range increases. How Much Power Will A Stock 4l60e Handle. 393gwI /BFC?jn"m&&v(2NgwI dS! 20 to 40 ohms, splice in design, twist locks connectors included. Another way to test your shift solenoids is to check the ohms of resistance with a multimeter. These are simple plugs that have a tab that is easily released. This kit does not work on 1996 and newer 4L60E transmissions.This kit contains:1-35391A (20 to 40 OHM) Universal lock-up solenoid2-35393A (20 to 40 OHM) Shift solenoids 2-35394A (9 to 14 OHM) PWM 3-2 downshift solenoids.

TCC PWM solenoid). 1-35399A (3.5 to 4.66 OHM) EPC solenoid 2-35394A (9 to 14 OHM) PWM 3-2 downshift solenoids. %} : }yS#22r.^x3TS l#'_qa'!ca29. The switch contacts are normally open and close when fluid pressure causes them to. The required fix was to overbore the TCC regulator valve and the AFL valve and replace them with oversize valves. There is a solenoid in your GM converter that causes the the torque convertor clutch (TCC) to engage and disengage.

Front pump internal passages different to match new TCC strategy. Here I use Ohms Law for testing. Shift solenoid 2 should be 12-28 Ohms. If the solenoid works, youll hear a clicking sound when you go to attach the 2nd wire to the battery. VSS (vehicle speed sensor) on 2WD vehicles is in transmission extension housing, on 4WD vehicles the VSS is in transfer-case. Hb```c``Q``e`(fe@ (C A1?4d71b`34

Some of them can burn you, even when you werent the one that performed them. Working with transmission builders to ensure they are buying a 4L60-E converter with lining best suited to their particular build or modifications is one of the keys to long converter life and avoiding modification-related comebacks. If you need printing, shipping, shredding, or mailbox services, visit us at 13725 Metcalf Ave. An erratic TCC lock up can be caused by an erratic input signal from the VSS (vehicle speed sensor). Instead a consistent slip of 20 to 40 RPM is maintained. 35386BH 4L60 4L65E Wire Harness Repair 2004-UP (4L80E 01-UP). There is no cleaning pulse (dither) every 10 seconds on this transmission (unlike the 4L80E). 4L60E transmission solenoids
Transmission Solenoid Testing. Earlier transmissions won't have this solenoid, so checking it will show an open circuit. Some other info, if leak test isnt accessable. Sonnax is an industry leader in the cutting edge design, manufacture and distribution of the highest quality products to the automotive aftermarket, commercial vehicle industries, and industrial sectors utilizing drivetrain technology. More Information, Replacement for cracked or broken lockup solenoid snout. Ramping this pressure in stages gives us the smooth operation and improved fuel economy were looking for. So just Ohm testing on its own is not really accurate. Typically the TCC solenoid itself costs under $30, so between that and fluid and a new filter (might as well change that while youre in there), you can be less than $100 into replacing a TCC solenoid yourself in a few hours. Locally owned and operated. 1 Prong normally open switch.

Pump is the same as '95. 2 required.No returns on installed electrical components. 0000001258 00000 n
A common problem with PWM and EC3 units is caused by continuous oscillation of the regulator valve, which creates bore wear over time that allows critical apply pressure to exhaust. 0000000886 00000 n
# The Lock-Up Feel (LUF) solenoid was probably put in high end Cadillacs for seamless shifting. 1996: The 3-2 downshift strategy was changed to an on /off arrangement. I believe that this is the only way to test your solenoids on or off the vehicle. While the extra pressure masks bore wear and provides a Band-Aid for TCC slip, it can lead to: These problems are made worse if line pressure modifications are performed which allow even higher pressures into the apply circuit. For 1996 and up, the 3/2 downshift solenoid should be 12-28 Ohms. But on/off operation had some shortcomings. 35380BH 4L60E 4L80E Output speed sensor, repair harness 1996-on. With anti-drainback valve. If you need to replace your shift solenoids, they are a pretty straightforward piece to remove and install. How an Internal Combustion Spark-Ignition Engine Works, Setting the Cold Start and Warm-Up Enrichments, Vehicle Speed Sensor (VSS) - has its own 2-pin connector, Sol A (1-2/3-4) Switched GND (aka. Common issues that may cause you to believe the 1-2 or 2-3 shift solenoids are failing are a bad accumulator, stuck shift valve, just to name a few. The cost associated with replacing a 4l60e TCC solenoid is not too bad, especially if youre comfortable doing it yourself. 0000001002 00000 n
