I know that's debatable.and yes, you must keep up with everything new coming out.but, not at the expense of your existing customers.as 99% of us don't have brand new/last year model vehicles.
#4l60e shift solenoid test software
Weird both, this software and 4L*0e's have been out so long.and the vast majority of GM based people have them.yet, this basic operating discrepancy hasn't been identified/fixed before now.Ī happy existing customer brings more business to the door, than trying to market new customers with software advances. HPTuners must revisit this entire software chain to make right. One can't be wrong and the other right.their both wrong. Yet, the on/off status for each 1-2/3-4 (supposed 2-3) Solenoid didn't change in the scan results? This shows, not only is the Scanner wrong, but the Controls and Special Functions is wrong as well. Third chart is my scan results after I'd swapped each 1-2/2-3 electrical connector around inside transmission at Valve body Second chart is what my original scan/results were for each gear
#4l60e shift solenoid test manual
Here's a pic of my handwritten scan/test results.įirst Chart is correct Solenoid operation per om the GM Service manual man, that truly threw me for a loop when I saw that.thus, knew, something had to be wrong in the HPTuners software. But.it doesn't change.the scan's on/off status stays the same wether both shift solenoids are wired correctly or backwards. If you swap the two solenoid's electrical connectors around, you should see the exact opposite on/off status for each Shift Solenoid 1-2/3-4 in both 2nd and 4th gear. JasonB, the truly wild part about this is - when you physically swap the 1-2 and 2-3 shift solenoid electrical connectors around inside transmission (at the valve body).then put it all back together and go for a drive/scan.the scanner's on/off status for each solenoid stays exactly the same as it was before you swapped them around. I've seen him work his magic a few times on here. Yet, they show up on the scanner as being right? (except the 3-4 is supposed to be 2-3).that threw me off too.thinking HPTuners software "simply had to be right".īILL at Support will get this ironed out quickly, for sure. When you click 1-2 on/off, it'll actually cycle the 2-3 solenoid on the valvebody.and visa-versa. I'm relieved.and yet, a bit aggravated over this.Īnd, in the first portion of your video, when your using Controls and Special Functions to manually cycle the 1-2/2-3 solenoids on/off.i can verify (twice) that if you drop your oil pan, those will be backwards as well.which is also on the same ticket I currently have in with BILL Support. Drained/dropped my trans oil pan twice.because I figured HPTuners couldn't be wrong on something this basic, especially since its been out there for years (both the software and 4L60e's). This cost me a lot of work, kicking big rocks around my yard, and spewing words a sailor would frown upon. Your shift solenoid 1-2/3-4 (supposed 2-3) on/off cycles exactly like mine in 1,2,3, and 4th gears.1st and 3rd are good.2nd and 4th Solenoid on/off are ass backwards. Dammit man, that's good work.you made my day bro/took a load off my shoulders. Difficult to believe this hasn't cropped up before/been fixed already.ĭamn fine work JasonB.,I never thought about making a video.,that's *uckin' genius that is. Chased my ass for 3 weeks over this issue, thinking either my newly rebuilt 4L60e/truck/0411PCM had something wrong! We must get this fixed, there's a lot of 4L60e transmissions on the road.and this is a fairly basic operating parameter/diagnostic aid/issue to fix.
You'll have to stop the video at each gear change and see the on/off status of the 1-2/3-4 (supposed 2-3) shift solenoids.Īppears everyone's is like this?.man, I'm glad it ain't just mine.and here I thought I had big problems in my truck somewhere. BILL HPTuners Support - look at the video JasonB made above (I'll email you too, under the same ticket number).JasonB nailed it perfectly.
