Scary issue with the 6L80 today - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

InFiD3ViL · 10-30-2021, 11:06 PM

So had a newer, very pretty 370z pull up next to me at a light today. Decided to let her rip, brought the rpms up just a little bit with my foot on the brake (stock convertor), and took off when the light changed. Left the 370 in the dust...for a moment.

Took off through first and the rpms just kept climbing and pegged the rev limiter. I had the car in regular Drive, not Competitive Mode. She wouldn't shift out of first and kept banging the limiter until I pulled off throttle (Ryan set my limiter at 7200 rpm, so she was screaming!). Looked down to make sure I somehow didn't leave it in manual mode, and I hadn't, The D was flashing on the DIC's gear indicator, but I didn't throw any codes. Never saw that before.

Once I let off throttle it eventually shifted and all was well. It ran perfectly fine after that and has been shifting perfectly. Put another 20 miles or so on her without so much as a peep. Shifts are nice and crisp through all gears, even more so in Comp Mode of course.

Fluid was changed around 15k ago, along with a wide mouth filter and new seal. I run Valvoline Max Life ATF, as that got rid of the occasional 2-3 shift flare I would get when running the Dexron VI.

TECHM glitch or failure imminent? Convertor issue? This has me nervous as hell as the 6L80 has 167k on her. It's had a TCM tune since around 70k, but I rarely beat on my car. I drive probably 95% using the paddles. I don't have a trans cooler, but temps are always decent, around 180. This just has me worried as my next mod is going to be a 4k convertor.

I have GM GDS2 software on the laptop, so I may do relearns/adapts tomorrow, but part of me thinks I should just let it be. Have a baby coming in 2 months, so the timing would be horrible if its on the way out..

Are you running the fluid level at the "stock" level? Or do you have a JRE dipstick and run it a half quart over? You may have had a fluid loss to the filter on the quick hit of the throttle and the sudden forward movement and it couldn't pick it up until you let off and it caught back up to the filter/pump. I had this happen a couple times going around a corner and romping on it and it downshifted and wouldn't upshift until I let off. Was kinda of annoying to say the least. And I was is sport mode which I drive in all the time.

Torque converter and or clutch pack. If it is at the proper fluid level, you would be hard pressed to slosh the fluid that much that it starves. Sometimes these new transmissions, such as the 6L 8L and 10L, have funky weird and erratic shifts. If it doesn't do it all the time, I wouldn't be too worried. But I would monitor it.

Not to question Ryan's tuning but 7200 rpm is pretty high for our engines. Especially for our camshaft with a stock intake and throttle body. Because we have almost the same build and I had my car dyno tuned and it stop building power at actually 6100 rpm but It carried that power until around 63-6400 rpm. I think my full throttle rpm shifts were set to 6400 by Ryan and my tuner. But the fuel cutoff was set to 7300 by Ryan at GPI and 6700 by the dyno tuner so I left it at 6700 and just changed my my wot revs in the transmission tune to 6300 and had to play around with the full throttle shift speed to get it to shift there because the full throttle shift rpm wasn't really working for me. I don't know about you but I can't really afford to blow my engine up. lol

That is exactly what he did with mine. 7200 on fuel cutoff. His exact words were 'have shift points and rev limit set, so you can run 3-4 wot pulls to the shift points. They should be mid to upper 6000s. Rev limit will be about 7200-7300'. I thought it was a bit high, but I trust him and figured if everything is working properly it should never hit cutoff.

As for the fluid levels? I used to run the JRE dipstick but took it off since it was vibrating and causing a rattle. I think mine is slightly bent and was hitting somewhere, so I removed it. Just never got around to reinstalling it. But I never filled it a half quart over. I need to do a fluid level check. When I last changed the fluid/filter, I went through the proper level check steps at the correct temps, but haven't checked since. I hadn't considered fluid slosh, but that's definitely something to think about. I def need to check levels.

The TCM certainly noticed something out of the ordinary though, since the D was flashing on the DIC. Low level scan tool shows no codes. I am going to break out the laptop with the GDS2 software and do a proper scan and check history.

1JEWLDSSRS · 11-01-2021, 08:59 AM

Good luck with it my friend. My Camaro after that escapade drove normal as it should, but it did put a WTF moment in my head and made me wonder about why it did that, also it was BEFORE I had the cam swap done. I got curious as to if it was a one time deal or something wrong so one day when I came to the same off ramp from the highway speeds and took the corner again at about 30 as before and romped on it the same way as before going up a slight incline it downshifted like before and kept going all the way to the limiter again and didn't shift but I was ready this time and tapped the upshift button on my steering wheel and it shifted to the next gear like normal. So I just never go around any corners and romp on it anymore. Straight line it NEVER did that.

AlanRubin · 11-03-2021, 01:51 AM

I have had actual solenoid issues, and "D" never blinked on me.
They're intermittent...

The GM Manual says the D on the dash will flash if a trouble code is being entered to
the Transmission Control Module. Yet, I have never seen it, and I get two trouble
codes when it acts up. It is from the TECM though...

Revving to 7200, I would surmise something went out of range, since it's not
supposed to rev that high. AS RPMs go up, solenoids are opened to increase
pressure on the clutches. It's not made to go to 7200.

A good scan-tool will be able to read the TCM to see what it was.

1JEWLDSSRS · 11-03-2021, 08:36 AM

Thanks Alan, great info. All I know is when mine did it nothing ever showed on the dash as a blinking "D" or any codes at all. Has never done it again except for those 2 times. Of course I have never gone around a bend/off ramp and romped on it again. Been quite a long while since it happened..

I’m pushing past 7200…no issue

Moto-Mojo · 11-03-2021, 09:31 PM

I’m Jxx tuned and on occasion the tranny hiccups. Nothing serious but it does seem anomalies exist. I try to put them out of my mind. :0

How long have you been pushing it that far? And what mods do you have? Or are you all stock? As I said OUR engines (mine and InFid3Vil) stop making power at 6100 rpm so why in the heck would you run it to 7200 rpm?

Just a note on that on my setup. My stock intake after we did the cam swap would only make power up to 6800 rpm, after I installed the LOD she made power up 7500 and wanted to keep going, but for safety sake we stopped there. So when I'm feeling frisky we run around 7000-7200 with it, no issues. The LOD moved the power curve to the right in the rpm range, and the 4500 stall makes up for the low end loss.. Maybe he has a better flowing intake on his too.

morepowerjoe · 11-04-2021, 08:40 AM

That's what I'm thinking too.

1JEWLDSSRS · 11-04-2021, 06:15 PM

Yea, because the stock one, and I think even the rod mod one doesn't make any more power past say 6800, depending on the cam and such.
