This visual demonstration is awesome. Thank you very much sir! I got my Superior STL010 installed last night. It did prevent the overheating. Highest temp remain high at 199degrees highway. Im happy with this, no leak. Prior to this had a nightmare of temp as high as 165degrees, tranny was leaking!!! On the same highway speed.
Something everyone should know is that Chevy issued a TSB and if you complain about high trans temps they will replace the TBV to the cooler 70°C one for free. If you live in a northern climate which gets cold this is what you want. The TBV delete kits are good in the summer but then your trans gets too cold in the winter.
Thanks for that… great demo! I have a Chevy suburban 2013 with a tow package… I can pull up to 8100lbs. I bought a travel trailer 5800lbs and my transmission got up too 210 degrees… before I pull again, what can I do to lower the temp!
Have you looked at the Transmission, HOW would you hook the line to a hole coming out of the transmission?? You would have to do some Serious modifications!
I never agreed with the direction automotive manufacturers that had a thermostat system for the transmission. What really had me torched was when I began to see this system but unfortunately the lube techs who were treated like dogs, were never trained onto service the Super Duty nor F-150 that had this system. They would receive the R.O. to see it's a 30k service ESP Ford then once after replacing items that are covered by this service plan, they would attach the BG transmission flush machine and brake tourqe the truck until the fluid was to temp for the thermostat to open, from experience with a customer's transmission started to shudder and slip, the damage from the lube techs put upon the transmission by cooking it.
@@codemansauto208 I'm working on a similar one with working pressure cant find clear that will take the psi, bet you know how messy in can get, but I really liked the mock up. Nice display
Great video thank you for this, really helps with the visual learning. I installed the surecool on my 2014 Silverado and it works great in the HWy it stays around 160° however in city driving It’s still gone up to 200° at times. Any ideas or suggestions? Also do you think if I swapped out my engine coolant thermostat to open at 194° rather than 207° would help with that. Thank you in advance.
It would help slightly on the tstadt drop, if it's running warm in town you need to add a second Cooler, like a Hayden or tru cool type in the front air flow.
Good video, I have a question I have a 2011 Chevy 1500 and all of a sudden I didn't have drive or reverse. Tho only code that shows is 0605 and that was lack of voltage to the ECM
Yes, your cooler also works to warm your transmission in cold temperatures because your engine heats up faster then your transmission, that was the design since automatics came out that where fluid cooled instead of air cooled
Hello, what about 2011 ? what should i do to bypass it ? i seen there is some item called Transmission Cooler Adapter With Thermostat did this will work for my 2011 transmission ?
the newest truck that we have serviced has been an 18 model so you may need to have someone to look under the truck on the driver side to see if it has one, I cant find this information on the 2021
your 2012 should not have this thermostat on it but if you plan on towing with it you should think about a larger external cooler and a billet style torque converter also be sure to upgrade your transmission fluid to Mobil one full synthetic LV HP
I installed the stl010 in my truck. For my curiosity I've been trying to figure out how it works and I think I got it. What they call the "piston" is hallow. The "Bushing" is also hallow with the steel check ball. The bushing has holes on top right below the two O rings. The check ball blocks the passage of those holes and stays in place with the cone spring. If a line is kinked or there is some type of blockage, the check ball is pushed towards the "piston" allowing the fluid to flow back into the trans. This is why it is important that the spring is NOT installed backwards. If it was, the check ball could not block off the holes in the "bushing" and it would not flow through the cooler. Am I right?
I loved seeing the demo there. So thats the flip? surecool ,or is that the trans go? Also I was wondering what about cold weather areas with the sure cool ? Is there a too cold?
no to cold and that was the transgo delete in the video i knew that i wouldnt have enough pressure with that pump to change the outcome of the sure cool
@@codemansauto208 thank you I was just wondering because I just did my 6l80e with the surecool and it's be colder in 20s out side thank you for making your video helped alot !
I have a GMC yukon 2011, I can't find out the problem that why the transmission is heating up even though my transmission has been overhauled, but it's still heating up. any suggestions?
yes take your top and bottom cooler lines off the radiator and flush the cooler from the top of the radiator forcing a back flush on your cooler this will clean the cooler on your radiator sometimes rebuilders will flush the cooler the same direction as the fluid flow and this method usually doesnt clean the cooler very well hope this helps you (use KoolerKleen)
Found out about this all too late had to have my transmission rebuilt ...and went to put in a bypassed system and they Took the thermostat out And drilled and tapped a plug in the bottom of it.. is that safe
It would be easier to understand if you stopped incorrectly using the word "delete". A delete is your second example. A aftermarket bypass valve is the first
@@codemansauto208,I just paid $2,675 to have my transmission rebuilt. Plus a $60 tow charge. As long as it’s cool out,the transmission temperature stays around 145 to 150. But I know I’m going to have to do something before it gets hot out again. That’s when the temperature runs high 180 to 190
So if you've plugged the bypass, if the cooler starts to plug or restrict flow from the cooler into the trans what do you do now? If you have plugged it your in trouble. = No flow.
No! There is no safety check ball. If there is a blockage in the line or cooler it will STOP the flow of oil and you will burn the trans. The check ball in the Stl010 will push back against the spring and allow oil flow back into the trans to get you to a safe location. Also it will equal the pressure so you don't have a delayed engagement into gear on a cold transmission.
Hey im currently debating between the stl010 , and the new updated GM bypass from the dealer , any suggestions? Im honestly leaning towards the rebuild kit just not sure how the updated GM differs
Original opens at 195. Updated one, stamped "70" means 70 Celsius = 158 degrees to open. "Flipping the pill" bypasses the thermostat to go to cooler 100% of the time - OK perhaps in warm climates, in cold areas, no warm up. If cooler stops up, your screwed. That's the point of the video.
To bad Chevy did'nt put the 400 turbo tranny in all their trucks,they were eternal.I'm selling my 14 Silverado and buying an older chevy truck,a dam shame.
The purpose of the thermostat is to let your trans warm up faster. Then when it reaches the thermostat temperature it opens to the cooler. This increase your MPG. A delete will cost you MPG because the trans takes so long to get to operating temperature.
yes that was the purpose for that design the only reason was to get your lock up to come on faster to drop RPM stay tuned for a video showing the difference in between the time it takes for the lock up to engage between a deleted and a stock transmission thermostat
If you happen to live in a hot state like Florida the factory setup will cook your torque converter in short order. This was a very bad call by GM and I understand they have fessed up to their sins and offer a replacement thermostat that opens up at a much cooler temperature. Now if they could just do away with their AFM they would have some pretty good trucks.
Basically, the Transmission fluid goes into the thermostat block and is diverted Back into the transmission by the thermostat when it is cold. When you take the thermostat out or DELETE it from the block the fluid goes to the radiator and then returns to the Transmission. But when you remove or DELETE the thermostat it leaves an open hole because when it heats up and moves forward it blocks hole A and that will send the fluid to the Radiator and when it cools down it blocks hole B and that sends the fluid back to the Transmission. This video was to show that you can't just remove or DELETE the thermostat without blocking off hole B.
@Mike yep, the original wouldn't prevent overheating, but the gm replacement thermal bypass valve opens at 158° instead of 194° so it should run significantly cooler and stay out of the tranny killing zone.
Flipped the pill on mine and dropped Temps by 30-40 degrees....a must do

Good demonstration. A little over explained, but I guess some ppl need it.
why not just bypass the thing all together? run the hoses like the old school way. one hose from trans to cooler, one hose from cooler to trans.
