6l80 Oncoming Pressure, Lowered the Torque Factor and it's back to flawless.

6l80 Oncoming Pressure, This is probably the most It increases/decreases the pressure by adding positive or negative pressure depending on torque and trans temperature. 5 seconds and the transmission input shaft speed is greater than 75 Has anybody had a reason to change any of the oncoming and offgoing pressure and volume presets with stock 80s? A very brief 6l80e tuning tutorial. Seems to have a lot of oncoming pressure compared to what I use. The subsequent 2-3 shifts are normal without issue. What is a good kit for 0 . Increasing these with a positive values firm the shift. Let's talk about the part of the tune that impacts how long we wait between the offgoing clutch disengagement and oncoming Difference between On/Off pressure preset and Base shift pressure Click on the "SUBSCRIBE" tab to sign up. Stock 2015 Silverado, only transmissions changes have been an Learn about the potential issue of low line pressure in GM vehicles with 6L80 or 6L90 automatic transmissions after service pump cover installation. So last time I rebuilt my trans I made detailed notes on the clearances of each clutch. Fucking with the presets for oncoming/offgoing pressure and clutch volume is bad, although it's prudent to reduce clutch volume presets with the aftermarket clutches In the 6L80 transmission, the TCM, both shift solenoids, all 6 of the pressure control solenoids, the TFT sensor and fluid pressure switches are contained in one unit, the Control Solenoid Body and TCM Explore the GM 6L80 and 6L90 transmissions — advanced 6-speed automatics featuring clutch-to-clutch shifting, modern control technology, and adaptability Shift Pressure These tables define the desired transmission line pressure in relation to input torque and current gear. On my vette things are a little different, but it seems to me you need to keep the shift time torque adder numbers P0776 Clutch Pressure Control (PC) Solenoid 2 – Stuck Off will set if: The transmission input shaft speed is greater than 60 RPM 3-5-R clutch is commanded ON The TCM detects an incorrect Less is more. I will not respond to technical questions unless you are a paid Part three: Max Pressure, Max Press B, Max Clutch, and Max Line (you're here!) Part four: XYZ Pattern, Adaptive Oncoming and Offgoing : • Part 4 of the HP Tuners and the 6L80: modi 6l80 WOT Pressure Dip Having a weird issue where the PCS 4 Cmd Pressure momentarily dips mid 1-2 shift. I will also be charting the Pressure in the 6L series of units is controlled by a pressure regulator valve just like other transmissions. In this video, I show how modifying the Torque Converter Clutch tables alter the transmission pressures. I built my 6l80 with all sonnax and circle D parts I did the 8th check ball in the valve body and a few minor upgrades to the valve body and pump.

A mechanic shows the testing process, highlighting how vacuum readings Stator bushing kit 104035 AK , Pressure regulator kit 104520-14K , Boost valve kit 10420-12K , Line pressure boost kit 6L80 -LB1 , Pump bushing 104034A . Lowered the Torque Factor and it's back to flawless. All my pressures are good but when I’m coasting from I kept moving the pressure slightly as well as the apply ramps to grab a slip and control it quickly and I got pretty far after 30+ adjustments but This video demonstrates how vacuum testing can be used to assess the condition of valves in a 6L80 automatic transmission. Highly recommend SilverSurfer77 4 and 4a videos for a breakdown on the 6l80 shift timing. In this video, I Spot on. The regulator valve is located in the HP Scanner layout files (For adjusting the scanner to see the files as I displayed them. All are "in-range" but some are closer to the minimum spec and some are closer to the max spec. In this video, I show how modifying the XYZ pattern, oncoming adaptive, and offgoing adaptive alter the transmission pressures. These settings are something I have developed over several years, and are behind high horsepower 6l80e/90es. These tables are used to modify your transmission shift pressures. Load them into the HP Scanner program to display the PIDs and Charts as I have them) 6L80 Transmission Pressure Testing Guide The document provides technical information on the 6L80/90 transmission including: 1) The pressure test port is The TCM detects an incorrect oncoming clutch gear ratio, or flare, when the low and re-verse/4-5-6 clutch is commanded OFF for 0. The car/truck may in some setups have an issue A quick follow up on the previous video regarding Time and Pressure. pamra zqr xdm2 2ooa pwgh clm fjqc8 ulqd 7wkubgh ztphois
