The Compushift module also provides a real-time display of transmission function data including range, fluid temperature, line pressure, etc. cycle to let 50 PSI reach the control valve. Finally, in 2009, GM eliminated the 3-2 On/Off downshift solenoid and replaced the pressure switch manifold with an internal mode switch. The Powertrain Control Module controls the solenoid by providing a ground path on the TCC PWM solenoid valve control circuit. I have a 93 one ton chevy with a 4l80e , my truck would not go into third gear or overdrive. Subaru OBD-I (1990-5) Trouble Codes This is an attempt to collect some of the less common information on some of the more esoteric codes here, rather than the full diagnostic procedure (which can be found in the service manual). Pictured below is the TCC solenoid. In forward ranges low pressure results. Secondly, put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Always better to be safe then sorry, it's a one hour job to change those solenoids VS a half a day to get the OD off rebuilt and back on. The replacement of the entire control is often considered the best, but there are many GM torque converter clutch solenoid available that can be merged in the entire control. A: 1-2 shift solenoid ground signal. The probable operation of the solenoid is that there is a default position of the solenoid in the middle where the transmission is derivable. From 1993 to 2008 the GM 4l60E transmission used a pressure switch manifold to tell the computer what gear was selected. Run engine. Overdrive Band, 4.

With lung pressure (or very low pressure) try to blow through the solenoid. All the '94^ EFI series use the soft-apply TCC with release upon decel - the pre-94 non-EFI series used a stand-alone TCM to control 4L80E functions - the solenoid was referred to as PWM TCC solenoid - having had no personal experience with the early series, I can neither confirm nor deny PWM function. But in 2006, GM decided to add an input shaft speed (ISS) sensor to the transmission for improved gear monitoring and pressure control, creating a new data parameter for the scan tool. This in turn has an effect on exactly how much pressure is going through the lines of the 4L60E at any given time. It would only act up during the first 3 minutes of operation. Connect a test light across converter clutch harness terminals. 4l80e valve body removal and electrical testing.

I thought it might be an internal problem so I swapped in transmission 2 hoping the problem would go away…and I’m having the exact same symptoms. The last owner of my truck replaced this transmission but it was new and never had the upgrades done to it. Its job is to control pressure as the computer commands it. It can be used in the vehicle, on a dyno and on a valve body machine to test and control the automatic transmission and mechatronics. Current flows through the solenoid coil according to the duty cycle (percentage of ON and OFF time). I adjusted line pressure positions in the tune, but don't get substantial changes in feel. Codes can be cleared by. Connect the solenoid to a 12-volt source. I mean there are 2 speed sensors on the left side, then theres the wiring harness that enters through the side. The plunger can also get stuck. So 60's aren't impressive but the light under the left wheel for a second was. Master Overhaul Kit with friction and steel plates, 2. We also have thousands of new parts too!. Shift solenoid malfunctions can be the result of a variety of both mechanical and electrical faults. It absolutly is labeled correctly and can show you where your solenoids are located you just have to look at it and pay attention, and compare it to your valve body. Noted below are a few of the indicators that the transmission oil pressure switch is damaged and needs to be replaced by a local ASE certified mechanic. NEW high quality GM 4L80E/4T80E Electronic Pressure Control Solenoid also known as the Force Motor for 2004 and up automatic transmissions. The PCM can vary the current from 0. The transmission pressure control solenoid controls the fluid pressure to the internal friction plate clutches or drum bands. In R: 64-75psi Min. The Powertrain Control Module controls the solenoid by providing a ground path on circuit 418. D: pressure control solenoid low. so we don’t want to run the higher current needed to directly engage the TCC solenoid through the pressure switch on a long-term. Check out our billet torque converters for 700R4, 4L60E, 200-4R, 4L80E, 6L80E, TH400, 4R70W, 4R100 and 48RE transmissions. In this article, I'll show you how to test the transmission shift solenoids (specifically 1-2 solenoid and 2-3 solenoid) on your GM 4. The dealer asked if I needed the 1-2, 2-3, or 3-4 solenoid. 0 out of 5 4L80E 1-2 A Shift Solenoid and 2-3 B Shift Solenoid. When the ECM signal stops, the solenoid closes the valve and pressure is vented causing the TCC to disengage. So if this pressure is low, the PWM solenoid will not influence the isolator valve sufficiently to raise converter clutch apply pressure. i'm using the tach output off the msd box. Learn what does P0748 Pressure Control Solenoid 'A' Electrical means, location and how to repair? The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil. Fluid level, color and smell are good. Transmission from the most popular brands at the lowest prices including sales on transmission, transmission le, kit, solenoid transmission, te transmission, s Car Automatic Transmission Parts. The case connector is updated to the latest design on pre-1994 versions and a vehicle harness pigtail is provided to address connection issues with the early design.
