Is the 4L70 really any better?

[@hotroddude6551]

I love Ryan's No BS, straight to the point. vids. Love my Performabuilt trans. Was behind a built 383 LTx, now it's getting ready for more abuse from a built LS2. I've had it since 2002 and no complaints. Only thing to ever fail was the converter that my tuner broke on the dyno. I may just send it to Ryan to have it inspected and possibly updated with all his new stuff.

[@richknudsen5781]

@@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.

[@PerformaBuiltTransmissions]

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.

Which of these transmissions you talked about should i get to put back in it? If it was your truck? Which stock trans would you put in it?

No difference in 4l60s from 1998 to 2005.

With stock motor with the same power can I go faster if I just change 4065e to a 70e or 80e with the same horsepower.

[@PerformaBuiltTransmissions]

Ratio reasearch and stall speed reasearch are what you want to explore

[@MichaelRoss-d1f]

in an AWD truck, like a 2003 Silverado SS, can a 4l70 be used? do you make adapters for the AWD transfer case? I know the 4L80's need new drive shafts, a new adapter to connect to the Tcase, and a wiring harness adapter.

[@PerformaBuiltTransmissions]

Why do you want a 70 in a 2003?

[@james10739]

So are all with the speed sensor a 70 because i rebuild a trans for a friend for an like 08 silverado and it did but i was under the impression it was a 60 and i think the kit i got used the power pack with thinner steels and clutches so there was already a lot more in the 3-4 clutch pack but im pretty sure it had 4 pin planetarys

[@PerformaBuiltTransmissions]

Not all 70s came with 5 pinions, only the trailblazer ss 4l70 from 2006 to 2008 did. All other 4l70s did not have 5 Pinions. If it was 08 its a 70 nomatter what vehicle.

[@highlander8198]

My 4L60e in my ‘02 Sierra has crapped the bed, and a friend has given me a great condition 4L70e (case code 6KMD) to swap in. I’m assuming I can just do a direct swap using my current harness and ignore that additional speed sensor…?

[@PerformaBuiltTransmissions]

Will work just fine. Pcm wont see the sensor

[@CorEdmonds]

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.

I have a 4L60E and a Terminator X Max and added a pressure sensor. Are the standard pressure setting ok or do you have a base recommended starting point? To find someone with knowledge and the Holley is hard to find.

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

[@hardball107]

Hate your delivery but love your facts and knowledge. I have run a cammed 5.3 LS with a 4L60 in an S10 up to roughly 475hp with great success. My current ride, A '68 C10 has a similar engine with a hotter cam and long tubes and I opted for the 4L80 because of the weight of the truck, larger tunnel and available space. Both trucks are very reliable and in a cruiser IMHO the 4L60 works just great, want to step it up ? 5 pinion planets and all the aftermarket goodies are out there for the 60 so have at it but the 80 handles the power and doesn't cost you an arm and a leg.

[@PerformaBuiltTransmissions]

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.

[@ohane1]

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.

Hey man, whats the real difference on the 1 Piece K housing and the non K housing on Fbody cars?

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.

Gosh DAMN IT! i just routed all my harnesses for my Terminator X max yesterday!! Is this 13 pin connector absolutely necessary? Only thing i see in the instructions from Holley is pre-2009 4L60-65e W/1.75 second gear ratio or W/1.63 second gear ratio

[@PerformaBuiltTransmissions]

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

👍

[@wickedwolverine350]

An ISS does not make it a 4L70E. There are 4L60E RPO M30 with an ISS, these had 4 pinion planetaries and controlled by a TCM. I believe when GM went from PCMs that controlled both the engine and trans to separate ECM and TCM that the TCM required an ISS, so to keep using the 4L60E it had to be upgraded to have an ISS. The 4L65E RPO M32 has 5 pinion planetaries, 7 clutches in the 3-4 pack, stronger input shaft, and a stronger forward sprag. The 4L70E RPO M70 has the same upgrades as a 4L65 plus a stronger output shaft. A 4L70E RPO M70 was only found in the TrailBlazer SS, 2006 GMT800 with LQ9 engine, and 2007 and 2008 GMT900 with L76 engine.

[@PerformaBuiltTransmissions]

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.
