Is the 4L70 really any better? 

Thats 95% of the car community sadly. And stubborn boomers.

Your welcome!!

Ive tried both. Short videos it seems in automotive esp on this channel tend to do better. I think its not so much length people are after but i feel they just want a direct answer to their issue and dont care about anything otherwise.

Check out some of my older build videos for performance parts suggestions if you havent already

@@PerformaBuiltTransmissions Been there done that but I have been confused a bit as to which parts are used in the different vintages of 4l60e like harnesses and valve body components. I have C5 Vettes and a cherry 2010 GMC canyon with the 5.3 v8 option and low rider handling kit so they all have different 4l60 requirements. Thank Again.

Valve body and harness setup for the c5 from 1997 to 2004 will be the same and you can use any valve body and harness out of any 4l60e or 65e from 1997 to 2006. The gmc canyon has a unique core and is set up in the style of 2009-2013 model valve body and harness. The only time the 4l60e got super weird is the three standalone years i.e 1993, 1994, and 1995.

@@PerformaBuiltTransmissions Appreciated Ryan, Thanks.

yes interchangeable

Its because they are the same in general. No difference that matters in function except the 70 iss if your vehicle requires it and is not on a standalone.

Stall speed, and rear gearing adjustment. Many videos available on the math to acheive what your trying to do.

You actually might have a rare exception because most of those came with 4L60Es not 4L70Es.

Its sad too many people want a racecar but shouldnt have one

Why do you want a 70 in a 2003?

Sorry, Working on it. And its been on my list. A video like that takes alot of time to put together and its getting peiced together but it will be awhile before all the screen captures are edited in. Im having staffing issues and a high demand lately so ive had to put alot of these kinds of things for youtube on the back burner for now. Quick videos like this dont require alot of work.

US Quick Shift is awesome. I have one running my Heavy Hauler.. TCI's EZ TCU sucked.

Depends on your trans builders build. We require a stock line pressure setting for ours.

Will work just fine. Pcm wont see the sensor

Can a 60 be used where a 70 once resided? What type of codes would it have and can hptuners tune out the fault code?

It can but you will have to go into the pcm and change the iss function from fitted to not fitted. This wont work with all pcms but most of them.

In the inner talks of the industry, the 80 isnt going to be cheaper much longer. Cores are getting destroyed and harder to get, the drums cant turn near as much rpm and are costly for aluminum ones. Reid just increased their prices immensely a few days ago. The 80 is about to cost more than the 60 by alot.

I have about 800hp going through a highly modified 4L70E... in a Saab 9-7X Aero. I'm seeing a little more metal flake than I like in the fluid but have done 0-60 in 3.37 w/ 1 ft rollout. 3.69 w/o.

My 4L70E has 5 pinion planet, 800hp Saab 9-7x Aero. (TBSS)

Might need to check your converter spacing as in its too tight past 1/8 or more likely your flexplate is wearing out and chewing up the pump backing. Not alot sheds metal flake in these transmissions except that.

@@PerformaBuiltTransmissions did that recently & was correct per Yank instructions. Thanks 4 reply! I will see when I open it up if it gets worse or stops working I guess. I just figured heavy vehicle + power = clutch wear? By "shavings" meant glitter btw...

99 percent of this was mentioned in the video minus codes... most people watching this dont want to get that into it and want it put simply. Simply is, The biggest difference between the 70 and the rest being basically a iss sensor is the key and major difference that came about in 2006 and primarily in 2007 and 2008 various model codes. Transmission slang is 2007 and 08 were pretty much in fact dubbed the 4l70e unofficially by nearly everyone in and out of the industry. Said 2006 trailblazer was mentioned in being the true 70 as well. You can also change most pcms or tcm iss input selection from fitted to not fitted as it was not an essential peice at all. Great info thats more detailed than i was tho.

Might be might not be. For the sake of video time and todays attention spans i did not cover every little vehicle. Some 06 models did have 70s like the trailblazer ss but its is extremely extremely rare. Youll just have to start running numbers your vin and rpo codes.

Holley x max usually requires a 15 pin not a 13. They list it broadly from 1996 to 2008 but left out the part that 2007 and 2008 are totally different from 1996 to 2005 / some 2006s. Consult your controller and harness you posess for a pin count. 13 is 60e and 15 is 70e

2008 silverado needs a 4l70E because of the electronics. You cant use a 4L60E. I would sell you our level 2 as well, you can veiw it and order at www.performabuilt.com

Casting is slightly thicker around the starter and dustcover area. Was meant for 4x4 trucks mostly and gm cut the ears off of each side for Fbodies because the cut would weaken the non K case around the cut area.

Depends how you build it. Making hard parts strong and last through function starts with the basic fundamentals of hydraulics.

Ys you can

Yes, You can swap it out for a 4l65 or 70 and there will be 0 issues with the computer.

@@PerformaBuiltTransmissions thank you so much for your response!! 2nd question..will running John Deere Hygard low viscosity tighten up the torque converter and buy me some time? lot of old timers recommend this but don't know the veracity if such a claim

I have lots of people that use hyguard no issue.

I am extremely condecending. I dont do feelings, just information. Im sick of people whining about every little thing tbh. If you had to deal with what i do everyday for the past decade + ... youd be pretty numb and fed up too

Well he's building your transmission, not trying to marry you. Ryan looks like a "No Filter Included" guy I'd drink a beer with.

I think it's just a general public idea of the customer is always right, when you're not, he's not mincing his words and that's about it.

You better harden up. This world isn't a kind place for soft people.

Nothing wrong with being stern and short.

Yes. Quote "Some 2006s namely the trailblazer ss" please rewatch

What I am getting at is that those are the oddball years, because mine does not have a ISS. It has a 13 pin green plug. But has M70 RPO code.

@@sierravmax Then its not a 4L70E. a 13 pin non iss 70 does not exist. If it has that code, it has to have ISS.

@PerformaBuilt Transmissions Not true. Truck has a 4l70e. Even the brochure they gave me says it when I bought the truck brand new. It is a Vortecmax with a LQ9. Reason is because it does not have a T42 TCM. ECU still controlled the trans. No point of installing a sensor.

@@sierravmax we can agree to disagree. you may have a rare case but overall its not truely correct, no iss means its just a glorified 4l65E
