CHEVY TRAILBLAZER TRANSMISSION COOLER UPGRADE (4L60E HEAT MANAGEMENT WITH DERALE 8000 SERIES COOLER)
HTML-код
- Опубликовано: 21 июл 2024
- The 4L60E is one of the most commonly used transmissions from GM and can be found in applications like the Chevy Trailblazer, Silverado, GMC Envoy, Oldsmobile Bravada, Saab 9-7X, and many more. Although it is a very popular transmission. It can be very unreliable. The #1 enemy of these transmissions is heat! In today's video. We upgrade my Chevy Trailblazer's transmission cooling system by installing an upgraded transmission cooler from Derale. With the help of the Derale 8000 series transmission cooler. The transmission temps should stay down and help extend the life of my new 4L60E. In this video, I show you all of the tools you will need for this installation and show you step-by-step how to upgrade your transmission cooling system so you can extend the life of your 4L60E transmission. If you found this video helpful, please give it a THUMBS UP and SUBSCRIBE to the channel for upcoming Trailblazer content. Thank you all for the continued support!

You're the trailblazer wizard. Love your videos can't wait to try some of the things you've done to my 2004 trailblazer. Your videos are perfect 👍
Thank you so much for the positive feedback! If you ever have any questions when upgrading your Trailblazer. Feel free to ask! Can’t wait to hear about what you do to yours 🙂 please subscribe to the channel if you haven’t already 😃
Impressive. Will have to look into doing this. Thanks for the video!
No problem at all! Thanks for watching, Felix! 😃
you and fritz ramos help me get so much knowledge for both of my cars that world seemed to forget about
I’m glad you’re enjoying the videos! Please give it a thumbs up and subscribe to the channel if you haven’t already. I have a lot more Trailblazer content on the way 🙂
@@PASSIONBUILT yep, i did half way through the bilstien video when i saw it in october, 99% the upgrade im gonna do in the spring, i might just go for the adjustable fronts to circumvent the leveling kit
That’s awesome! Thank you for subbing.
Let me know which route you end up going with for your suspension build. 🙂
Awesome video!!! Gonna have to do this to my TB. Keep the videos coming! Thanks
Thank you for the great feedback! I will for sure. Plenty of Trailblazer content coming in 2022! Make sure you subscribe, hit that notification bell, and give the video a thumbs up. It really helps the channel out! 😃
@@PASSIONBUILT any more TB videos in the near future? Don’t put it on the back burner for to long LOL I’m already subscribed and I’ve liked all the TB videos. So please keep them coming
Yes there are more Trailblazer videos on the way. Last week’s video was supposed to be a Trailblazer video. I made a video on how to rebuild your center console armrest and the video was great until it came to assembly and installation. The rebuild kit that I bought from eBay had terrible alignment with the bolt holes for the upper lid and underside. I was able to assemble it but when I went to install it. It didn’t work as it should. So I ended up having to use the upper portion from my OEM center console and the lower latching portion from the rebuild kit. I was very disappointed with the quality of the kit and ended up deleting that video because I didn’t want anyone to buy the same rebuild kit and have installation issues. But yeah. Trailblazer videos are coming soon. 😃👍🏼
Dude. I’m proud of you! Keep it up. If you wanna install some parts on my ram…lmk nice video!
Thanks man! I appreciate it! Honestly, I have my hands full with content off of my own vehicles at the moment. Maybe one day if I ever run short on content. Or if you get another Miata I would love to pick some content up off that as it falls in line with my Miata content. I’m trying to stick to content that I can create regularly. So for right now Suzuki SV650/SV1000 content, Chevy Trailblazer content, Miata content, and then next year I’ll be adding my CRF250R and my sons JR50 to the channel to add some more variety in.
The round plastic piece you called a dust cover is actually a much more important piece, i learned the hard way 😅 it holds tension inward on that little snap ring thats under it. Without that little bit of tension from that plastic piece, the transmission line can force that ring off and cause you to blow a line out. Happened to me at 60mph and 2hrs from home on the interstate
Sorry to hear that happened to you. Hope it didn’t cause any damage to your transmission.
How did you hold the bottom part of the cooler? love the video, so helpful!
I have a 2007 trailblazer and it has 280,000 miles on it and the 4.2 engine and transmission run great no slip no leaks AC works and I paid 2000.00 for it I don't want to sell it I wish all my vehicles ran like the trailblazer
My Trailblazer hit 250,500 miles and the transmission finally decided to go out. But after replacing it. She’s back on the road and driving perfect again. I hope I can get another quarter million miles out of my Trailblazer. It has been one of the best vehicles I’ve ever owned. I paid $2,500 for it about 4 or 5 years ago. Prices have almost tripled since then. I’m glad I got mine for a good deal. I hope yours continues to last you many miles 🙂
Just to back up your " public service announcement" at the end. definitely....definitely do a leak/drive/switch through all gears. Glad i did, i had to use a heat gun like you to put hose over the flares. I had a catastrophic failure at the hose. Luckily didnt drive far. Thinking the heat gun weakened the hose? Anyway...i lost just about a quart of fluid. Gave myself extra hose during install luckily. Cut the failed area and reinstalled...no leaks yet. Hopefully fixed the issue.
Glad to hear you caught it before something catastrophic happened. Hope it holds up and works out for you. Thanks for watching 🙂
So the 2 hoses coming off the cooler don't have a specific way they go on. Dosen't matter which hose goes where when they attach to the factory linesn
Thanks for this vid. I just got a Saab 97x and the owner gave me a cooler. Looks just like yours. So the trans fluid is pressurized? And will just flow up and down those lines you installed? I’m a noob when it comes to trans coolers
No problem. Thanks for watching! Yes. The lines are pressurized.
nice job brother! i went to the scrap yard and chopped the end off one of the lines from a donor so i didnt have to cut the lines on my truck in case i wanted to quickly revert back for any reason
Thanks for the love, Robert! I hope everything is going well with your transmission swap! 🙂
I'm condused. so you didn't cut into your existing lines? you are just running the cooler alone and not having the fluid go through the radiator?
@adamharlow8124 I still did I just didn't cut the original lines
@adamharlow8124 the part where he cut instead of cutting mine I cut one from the donor and just ran my hose off the uncut end of mine and then used the scrap one for the other end. That way if I needed to remove the cooler instead of my line being cut I could just pull the hose off and plug it right back in to the quick connect
@@rabmanrabman ah. Okay. I’m with ya. Sorry, I don’t know why I didn’t understand that. So in this video he’s running the after market cooler AND the stock cooler right ?
My transmission finally blew does the trans cooler make a difference and if so I’m going to get a used trans do you think it would help it out?
The transmission cooler definitely helps keep the temps down. Since I’ve installed my rebuilt transmission, it has been shifting perfectly and hasn’t had any issues. I highly recommend just getting your existing unit rebuilt or buy a rebuilt unit if you have the means for it. Installing a used 4L60E isn’t ideal unless it has known low mileage and has been fully tested with no signs of slipping. I made a separate video of where I got my 4L60E from. Check it out.
sorry I'm a bit slow and maybe a silly question. but so with this mod you did, your running the fluid through the radiator and also the aux cooler? so you didn't delete the original cooler you just are now running essentially 2 coolers?
Yes. Im running it inline with the factory system. The factory system is inadequate. Unlike the Silverados that got an independent functional transmission cooler. The Trailblazer just got one built into the radiator tank so it doesn’t really do much cooling. This remote cooler helps reduce transmission temps much better than the factory “cooler”.
What size/type of tires do you have? I'm trying to find what the largest size is I can install without spacers.
I believe they are 225/70/16 Falken Wildpeak A/T3
Hey, just trying to figure out why you didn’t tap into the other line why did you put the hoses to one side and not the other. Thanks
No need to tap into the other line. We’re just adding an external cooler since there really isn’t one on the 4.2 model trailblazers. So we are teeing into one of the factory hardlines to allow the cooler to be installed.
@@PASSIONBUILT thanks i was asking because i plan to do the same thank you
Just use the double flare cap for the bubble on your flares and skip the second step without it so they aren't sharp anymore and I won't be mad at you. You just need a little bubble. Won't leave a sharp edge and it makes the hose easier to slip on. That hurt me watching it. lol
Not my proudest moment on making a flare but they’re still holding up and working well. Thanks for your feedback on this. I appreciate it!
Questions hows The performance from when u did, to now..... ima Follow your steps tomorrow but before I do just wanna knw how is it boss
It’s been great. Since installing this cooler with a fresh transmission. I have had no issues at all. I’ve towed a couple of cars. No slips and no signs of the transmission getting too hot. I live in Florida and the heat is brutal down here. The cooler definitely helps keep the trans temps down.
@@PASSIONBUILT thanks
No problem at all.
How has the cooler performed so far.. you happen to have a part #
The cooler has performed well. Check the video description. The link to the same cooler is there.
Question I was told I have the 4L70 trans. How do I found out
If you have a Trailblazer SS. You have a 4L70.
Trailblazer still running strong? I just bought one and going to install the same Trans cooler today
Yes it is! I believe I’m a little over 20k since installing the new transmission and cooler. Good luck with your installation!
Thank you brother 🙏🏾
@@PASSIONBUILT That line you cut in the video. Is that the return line? Also is the new cooler spiced in with the old cooler?
@@shawnjs260yeah the new cooler is in series with the stock cooler in the video. I’m unsure which line he’s splicing but I’m assuming you want to splice the inlet line ?
do you still have he TB and hows the trans and cooler holding up
Of course I still have my Trailblazer. We just hit 20,000 miles on the new transmission and she is still running perfect since the install with the cooler. 😎👍🏼
@@PASSIONBUILThave you had any issue w the cooler so far ? or is it working how’s it’s supposed to work ?
No issues at all. About to hit 35k miles since the cooler and transmission install.
Will a 350 bolt up to the trailblazer 4x4 transmission
Honestly couldn’t tell you 😅
Yes.. just didffent bell houses
Copy that 😊😊
Hmm... that doesn't look like an sv650 🤔🧐
🤣
Lmao! Sorry, Oscar! Next video will be an SV video. Not all content on this channel is SV related. This is an all around motorsports channel which includes building my Trailblazer, both of my Miatas, both of my SVs, and soon we will be introducing my Honda CRF250R and my son’s Suzuki JR50. Hope you stick around and enjoy all of the content! 🙂
All good. Just bustin your chops
Haha all good buddy. It’s funny because when I went a while without posting Trailblazer content and was only posting SV content. I had Trailblazer guys commenting on the SV videos asking where the Trailblazer content was at lol
So now I’m just trying to post SV content one week, Trailblazer the next, SV the next, then Miata the next to try and have a good variety of content for everyone to enjoy while still sticking to the roots of this channel 😃
Thanks for sticking around and supporting the channel, Oscar 😎
