My check engine light and a transmission hot idle engine msg came up on my dashboard. The transmission fluid got up to 234 when I check. A mechanic said my transmission is bad. He didn’t test it out, he just went with what I told him. He charges 3,500 to fix my transmission. He wont swap het, he will just replace all the parts inside the transmission. Im not sure if there’s actually a need to do all that. Can someone help me?

My favorite generation F-series. I own a 2002 SVT Lightning with 32k miles. And I love it!!!

Ia there oem replacement or gotta get a after market one?

😭😭😭 this hot transmission came on today an didn't think it be all this

Stick to 6 cylinder and if its 4x4 make sure it's manual on the floor

I have a 2003 with 215,000 running strong😊…I just changed the rotors and it feels safer… Installing a 10” New speakers 🔊 miniature amplifier and putting 35’s next month…

goodyear better than michelin? nonsense

I have a 2017 Silverado 4X4 Long Box (6’ 6 “) - Crew Cab, 6.2 L Engine with A/C Seats. Owned since New-172,800 KM (Canada), now experiencing leaking rear brake light. GM Sells no replacement Gasket-Only Sells a New 3rd Brake light…. Ridiculous!!! Cost for a New one $150.00 Cdn. Also hydraulic / electrical Pressure Switch needs replacing. Intermittently works now, controls ABS/TRAILER BRAKE/ STABILITRAK System warning message shows up. $2500.00 Cdn to replace. Non-Repairable Module.

236 temperature I’m truck

220 not going down

Great insight I just bought a 3rd gen cummins dully with 77k notes with be taken More cummins content !!!

So we just remove that thermo bypass valve ??? Or add a thermo bypass valve. I’m lost. Sorry.

Did your truck come with an AOD? Or was it C6?

Starting on your day 1 and working all the way through. You are for sure a natural for KZbin. I’ve got an 89 and LOVE it.

I got my front from 1aauto and redid most of the front end suspension and did the work myself for around 300$

Changed the bypass valve on my 2017 Sierra yesterday. Temperature went from 190 deg. To 145 deg!!!

Totally agree with you

I completely bypassed my valve by buying cooler lines for the 2013 (no valve) Added a $20 cooler In the winter towing a trailer i was getting up to 210’ Summer now 90-100 degree weather and my trans stays at 165-170 and no more trans slipping or random shifts LITERALLY LIFE CHANGING

Thanks

Those rims are the same that Jeep use on their KL Trailhawks but this one is all alu and not alu/black.

Then my converter never locks up until I’m almost overheating. I run at 170s even when towing my camper I don’t go over 190. Only time it heats up is when I’m plowing hard and I’ve gotten it up to 240s 250.

Thanks for the info

Never had any good luck with my Sierra. Trans at 223. And a lot of little nitpick problems like bad grounds

I seen many video's on trans thermostat but what about fluid type . GM has two, one i believe is semi synthetic other full synthetic. Has anyone tested temp readings using either fluid vs valvoline or amsoil. I would think using different fluid would get different results.

I bought a ls6 from a cts-v. I've pulled a few ls motors apart even a ls1 once but usually its just blow the dirt off and send it.But the ls6 actually wanted a nice refresh for my 99' ss . I gotta say it really impressed me. Not just did I find Gen 4 rods and floating pistons. But the rotating assembly had grind marks from gm balanced the motor and other things like the crankshaft was gun drilled are valves are stainless with hollowed Sodium filled exhaust. The oil pump was ported and even rockers were a different ratio.

Brudah,those are not the original rotors,rest assure its the 3rd ones

Gas

Great video, we have one as well and we love it, does like has though! 😊

where did you get them

My truck is a 2015 120k miles. It got the trans temp up to 240 and started shifting weird. Do you think this will fix it? Or is it toast ?

My silverado 2018 lt transmission is overheating goes 278 degrees 😢 only 70k miles. You guys think that if install the bypass it will help. No check engine light on!

3/2024: Good Day. I bought my 2004 Z06 Commemorative Corvette New. It now has 131,000 miles on it. I have had it up to 176 MPH once. Never raced it, treated it well, but really enjoyed it. No leaks, runs like new and gets good gas milage on the highway. Truthfully, it still has the factory original clutch. While it was under warranty, the dealer did replace the oil pump. Great Engine and your comments are in line with what I am aware of. I'm an old MOPAR Guy. I've owned three 440 magnums, a 383, a 340 and a 318, back in the day. Loved um. This LS6 is the finest engine that I have owned. Thanks for this post & Best Regards.

I got the exact same truck same color 4x4 Great truck!

horrible truck, 2 lifter repairs, never had a ac problem but also on the 3rd transmission rebuild in 223k miles 2015 gmc sierra 5.3 most unreliable truck. buy a 13ford 261k or 17toyota 378k all stock no problems

I have a 5.3 and a 5.7 ls6 and they both chug oil. My ls6 only has 34k miles.

I had a friend tell me about this problem on his truck, I had no idea. Then, I started checking on my 2015 Sierra, and it was running between 195 to 204 degrees.. so I bought that kit superior solutions tech,. I paid 35 dollars for it. So today, i changed to transmission fluid, filter, and installed the superior solutions thermal bypass. It works really well. I drove it about 6 or 7 miles, and the temp only got up to 133.

GM put out an updated Bypass that is set at about 150 degrees and it is to replace the 194

Looks very nice.

I was wondering if the last year on this gen of gmc(2018)is the best year to get

I had the chatter at 146,000 miles. I had some metal fines in the pan but not bad. I swapped the converter with a billet from Florida Torque Converters. All good now.

What they lack in power they more than make up for in comfort, very nice truck. I just bought on yesterday 2003 5.4 63k original owner miles.

I put a 2002 ls6 in a my 4gen camaro ss. Great engine....eventually it went 10.7@130 with just bolt ons. Had 90k miles on it.

Mine is at 65565 and I got the warning 😢

I know its an old video and ypu probably dont own the truck any more but how was the handling on does 275 65 20 did you have any rubbing on inner wells

Can I just run the lines directly into the transmission or will it mess my transmission up without a bypass valve on it?

I just installed the Superior Solutions STL010 thermostat kit. Even though I don't tow a lot and the temp was ~190F, it now runs ~40F cooler. I welded an O2 bung as a drain plug on a replacement pan at the first filter change and do drain & fills every second oil change. I deleted AFM with a tune right after I got the truck at 21K. Sonnax has a great page on why the converters on these are marginal and prone to failure. I plan on replacing the ATF with Mobil1 LV HP ATF 'blue label' next. 96K and crossing my fingers.

i have 2014 Silverado 61,000 miles, trans would be steady at 190-95. put this in now 165-75

It’s been a bit? Do you still have it and what is your thoughts or final thoughts on owning one of these?

Thermostat delete

Maybe I missed it. But what size engine is the video, and does it matter? I have the 2015 4.3L v6 with overheating. Do they all have the same transmission, and thermal valve?
