I was thinking 12.8xx @ 106.xx honestly. What's going on with the 2-3 shift? I know with the 80E in my truck, I'm having to set max shift RPM at 5000 and set the MPH where I want it so it doesn't over run the commanded RPM. When I had it set by RPM and MPH (6100 RPM) I was getting 6500-6600 RPM upshifts. On the recommendation of a few people, I set my max RPM to 5000 and left the MPH the same. On the street, it seems to have fixed it, I am going to the 1st Funday Sunday of the new year to see if I can go faster with it shifting lower. The cam peaks around 5600 and carries to 6000-6100, never pulled it to 6500-6600 on the dyno - so no idea how hard it is or isn't falling off up there. Prior to a gear swap, I had gotten my best ETs and MPH shifting at 6100. Also, what day was this? It looked like December 10th by the time slips.
@@J-Whit Damn, I had no clue they were running yesterday. Opportunity missed. I really want to try different shift points and find my sweet spot. Then, torque converter swap.
@@J-Whit Hopefully the weather is agreeable on the 7th. 🤞 I went 13.289 @ 103.77 last month in good air - with it shifting in the twilight zone. I think I can improve that a tenth with proper shift points. Then I'd like to try stalling it up against the brakes as high as it will go. Thus far, light burnout and leaving off idle yields the best results. 1.959 sixty foot best so far. (Converter is too tight, I feel your pain despite different combos)
@@J-Whit That's not an issue. We did a 6L80 my neighbor's 04 lifted 4x4 TB with 4.2l a few yrs ago. He follows you on the 4200 or something forum. He just reported 15k since the conversion, towing a camper all over the place. With the 4.03 first gear and better spaced gears, your E67 will not freak out so much between manifold pressure changes during shifts. And your turbo will stay on its efficiency "boost" curve. That 1-2 and 3-4 of a 4Lslippy just suuuuuucks! Lol
That last pass was nice! We heard you get up & back in it at the top end just before the finish & that may have hurt just a scoche bit on your time but that was a really nice pass! Like she still wanted to keep going 😁👍🏾 Once you do something with those gears & maybe a higher stall would definitely help your launch I'm thinking 🤔 Don't know how much that transmission can handle as is but i'm sure a line lock somewhere in the future wouldn't hurt. Congratulations my dude, really exciting to see that 4200 getting down the track😁👍🏾
Also what was your 1/8 time on the fadt pass. I was trying see it but you never help the slip still 😂😂😂😂😂. I'm a 1/8 mile racer so it more applies to me
@@J-Whit Wow can make alot of trouble to many sport cars... I tuned my Isuzu Rodeo (in the Usa i think its called Isuzu Amigo) from 205hp to 225hp its much faster on the higher rpms... You can see me here drag racing in the sand dunes: th-cam.com/video/tiPJecFzjDY/w-d-xo.htmlsi=PjeaJpm-tttia-Tu
"we" need to work on that transmission next suggest transgo shift kit + transgo separator plate + sonnax pinless accumulator piston kit. I'll link them to you on FB. can do all from the bottom without dropping trans. Drop pan, drop valve body, follow directions in the kit. If you can do a turbo you can do this! I rebuilt the trans in my tired 4.2 2wd TB and did these upgrades and had it chirping 2nd gear shifts like your uncle's old camaro, it was a hoot Or does it slip 3rd gear in normal driving too? If so, then rebuild/overhaul/refresh time, same as all other 4L60 ever.
Is it ok for oil pressure to be that low at idle or is there a sensor issue? My mom had an Envoy awd 4.2 and always idled around 40psi like most GM trucks in this era. Not being an ass, just genuinely wondering why, would assume with the turbo it would be higher than normal, even at idle.
its also not shifting into 3rd. its doing like 90% of the track in first and second then hits the limiter around the 1000ft mark when trying to shift into 3rd.
This is extremely impressive. And what boggles my mind is that it still has so much left in it. 3rd gear, lower gears, stronger trans that will hold a higher stall converter, taking seats out for weight. I cant remember. Do you have calvins camshaft upgrade in it?
Its still running stock cams at the moment. But you are right and thats why im so happy it ran this in its current form. Just shows how much further it can go.
You can do quite a bit with trans tuning and a Corvette servo. Also making sure trans fluid and filter are clean. Knock the shift timing in half with HP tuners. Bump line pressure 10 percent to start. Also raise shift speed 5 mph across the board. Idk if you've done any of this already but trans sounds lazy for sure when shifting. Oh yeah and change shift pattern I think it is called to performance. One last thing the stock i6 converter stalls around 2600 to maybe 2800 at best considered the poor man's stall on a V8 application so that's helping you as is evident on last launch.
@edgallimore2843 i know pressure has been bumped and torque management adjusted. Not sure on the shift points etc. When i go back i plan to manually shift it.
im looking into a 2step possibility. thats what 2 step does kind of. it will cut spark at a certain rpm to allow it to build boost and hold at a set rpm. stock computer makes it challenging.
@@J-Whit Once in awhile, all the good parts come together at the hands of a good technician, who was having a good day, and that unit made it into your GMT360. When I worked at a driveline/transmission shop, they wouldn't warranty a 4L60 behind more than 400 hp, especially trucks and SUV's. Any plans for when (if) it expires ?
@@J-Whit had to sub, too. Looking forward to seeing this play out. I passed on a free 07 T/B engine that was going to be scrapped, because I didn't want to burn up a Saturday (already had plans) pulling it before it was gone Monday. The 6L controller is interesting, and I will be looking into that, most 6L failures come from the torque converter sprag failing, and "making metal" , I believe that running the engine in DOD mode makes it worse. Factory programming has the converter clutch being PWM applied in second gear, too, when it really could wait until vehicle speed is above 40 mph, but GM is trying to get every mpg they can. Staying tuned, good luck.
I dont think the turbo is a problem. This has made over 600whp on a stock atlas long block. Once we turn it up we will advance the vvt exhaust cam angle to get it to spool quick then retard the angle going down the track. But right now the trans, converter and gearing are all stock. Once we start upgrading those components it will perform better.
I bought a new '06 Trailblazer EXT with a 4.2 Vortec. The engine and drivetrain now have 170k trouble-free miles on the odometer. For several years I have considered buying a truck with which to replace it, but the prices have simply been outrageous. So I think I will just drive it for another 100K miles, or at least until we get rid of Biden and the chaos he is causing in the auto industry with his ridiculous and stupid EV mandates has run its course.
Great trucks GMC Envoy and Chevy Trailblazer basically a small GMC Yukon and Chevy Tahoe definitely a gmc envoy xl the envoy xl is only one inch shorter than a gmc Yukon and Chevy Tahoe
Before seeing the last pass I was gonna say it looks like you're suffering from turbo lag. If so maybe why 3rd was better if you launched at higher rpm. If thats case maybe try retard timing down low to build more egt to help spin the turbo sooner...maybe
@blueridgemountainprepper2166 the turbo spools pretty decent but the gearing isnt ideal at the moment. Since i cant get it to build almost any boost im leaving the line on almost nothing. That will soon change.

Buying a 07 TB today. Has 144k on it. 2wd. Plans are coming from this! My brother builds race cars so he's happy lol. 12.7 is nuts in that suv.
it can be a pain in the butt at time during the build but it will be worth it when its done!
Now it's time for a built 60e
Bingo
We need to talk about getting you a 6 speed in there (6L50 or 6L80). You'll be in 11's!
That would be slick! May be getting a built 60e soon with a transbrake.
Only issue is the bellhousing. Plus i want to keep it awd. Not super married to that idea but the awd aspect makes it fun to launch.

Thanks for the video. This is why I love my Chevy Trailblazer 4200...
how much hp?
previously with meth only and no intercooler it made 440whp on the dyno. now with the a2w intercooler, it is making about 500whp.

Congratulations and keep working hard...🎉
Like this simple but complicated.
I don't care how but im do what yall did to the 4.2 in my trailblazer like you whatever happen is ok

oh i put it back in 4wd. it ran a 12.7 in 4wd
Good job

It doesnt slip third, but it doesnt like shifting into it under load, which is why it bounces the limiter in second unless i lift a little lol

I havent figured out the speedo issue yet. And 2psi is the mpst i can launch it at lol

Fuel cut
What was the deal with not shifting out of 3rd
Its been doing that from the begnining. We have a few theories but still arent sure.

Get rid of some extra weight. the passenger seats and so.

around the speed of the slip. 105ish. but the problem is im going to put a much more aggressive gear in it and i will need third without a doubt.
