Sonnax 1-2 accumulator piston 4l60e 700r4 Harsh 1-2 Shift 

Sorry to be off topic but does any of you know a trick to log back into an instagram account? I somehow forgot my login password. I love any assistance you can give me!

@Payton Jeremias instablaster :)

@Jeremiah Deangelo Thanks for your reply. I got to the site through google and Im trying it out now. Seems to take a while so I will get back to you later when my account password hopefully is recovered.

@Jeremiah Deangelo It worked and I actually got access to my account again. I'm so happy! Thank you so much you saved my ass :D

@Payton Jeremias glad I could help :)

Did you replace the accumulator? if so did the hard shift go away? Or what was done for your hard shifts to go away?

@@frankiando30 yes new acumulator and new oil filter service that did the job.👍

In the description there is a link! Hopefully that will work for you

Awesome! Thanks for watching

Ya I'm not sure how well I staked them just because it's recessed and all but that's a good idea

Crack my housing trying to stake the ball. Tapping the next ones 👍

Hi David Moreno, When: while replacing The 1st to 2nd gear Shift accumulator valve located next to the valve body. Apply Is a generous amount of automatic transmission assembly lube directly on the accumulator piston and in the bore. The piston has a Teflon or Rubber ring The Lube is similar to Vaseline & allows smooth assembly. Automatic Transmission assembly lube Is designed to dissolve away. Recommended brands: ATP, ASSEMBLY GOO or SMART BLEND. The LUBE will be GREEN or BLUE in color. In the old days we used Vaseline they are similar in Is texture & viscosity. Kenneth ^

If it’s intermittent I doubt it’s a mechanical problem. Try disconnecting and reconnecting the wiring harness to the transmission to clean those contacts. If you decide to check solenoid resistance, do it all the way from the ECM-side harness connection to check the wiring and connection integrity.

@@testmcgee9230 Thanks man. it wound up being that my Bank2 O2 sensor wasnt working. replaced and now all is smooth.

@@atxjax1 really? All because of an 02 sensor? What brand did you replace with?

@@budthechud3408 It was because when I put my headers on I put the upstream O2 too far from the exhaust stream.

Very interesting idea! I’ll try that if I ever get my hands on another Chevy haha

If have valvebody off always take the 3/4 accumulator you put two of them in that hole one like supposed to go and another upside down no spring you do this on all 4l60 to improve 4th gear

servo

IRONWOLF _OMEGA Sorry for the late reply, but yes it did! I also did several transmission upgrades, the list is located in the description. Thanks for watching

Hey there, thank you for watching! I have read that it is 8lb/ft on each bolt, according to this link: www.gmtransmissionparts.com/4l60e-torque-specs/

Hi there! While I did have a hard 1-2 transition, it wasn’t anything that I would consider a slam. May I ask what your mileage is? I would do a fluid drain and fill, as well as replace your filter, 1-2 accumulator, and your A and B shift solenoids.

Could you provide a link where sonnax mentions discarding the inner spring? I'm curious because I've never read that before. Thank you

I don't believe any on this info is correct. Stiffer springs give you a stiffer shift. And the kit I got from sonnax came with both inner and outer springs.

@@beetee801 ur wrong

@@anthonycrosier8824 yea, I did the research and I stand corrected.

I bought my 08 new its a virgin , there was only one spring in mine , the bigger one , 334,000 miles its never been to a shop , ive done all the services so i know its original . It didnt fix my missing second gear , it might be the band is gone , but im gonna check that 1 2 ball in the valve body plate , i got another rebuilt tranny 2wd ,but it got flooded with water , mines 4wd ..im gonna swap the valve body ,after i clean it up , i think my band is burnt though , gotta try anyway ..glad i got a hoist ..

William Birnbaum The 2nd ball is for the 700r4 accumulator housing, as this kit is compliant for both. The 1-2 accumulator will not have a affect on your Park to Drive shifting error. There is a Forward accumulator that can possibly be your issue. I would make sure your engine is idling properly, as a high idle will cause a “kick” when selecting a gear.

"U" joints

That might be in the tune but I don't know

Same problem....And can't get a proper answer anywhere..

The GMC Sierra forum explains about 10 symptoms and fixes that's why I'm looking at the first second shift accumulator because when I go from first I have to rev it up to 23 mph or so and come off the gas and then it goes into second

@@juanmarshall4083 did you ever resolve the issue? Having exactly the same with my 02 'Avalanche

This applies to your model! They’re very much the same transmission, except 2011+ gets a little tricky.

I got a 1996 and my accumulator is different on my 4L60E@@howtofrank502

When your transmission shifts harder than usual, it breaks off tiny bits of clutch material every time. If this happens too much, one of the clutch packs will fully degrade and your transmission will not shift at all! The 4L60E is a fairly fragile transmission, so ignoring a repair wouldn’t be the best idea. Thanks for watching!

When/where would you apply the transmission assembly lube ?

Hi David Moreno, When: while replacing The 1st to 2nd gear Shift accumulator valve located next to the valve body.

did you fix it?

Try tcc valve

Hey brother any luck figuring out the problem? I’m having a similar one right now.

chris chris Hey there! I did not have a code. That seems to be a code for your Vehicle Speed Sensor, please watch this video for help replacing it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EHrJi9cXdTo.html

Hey there Rodney, please click the link posted to purchase the part: Sonnax 4L60 4L60E 4L65-E & 4L70-E Pinless Accumulator Piston Kit www.amazon.com/dp/B00BCN9Z5A/ref=cm_sw_r_cp_api_i_1PM-Eb9CZBCPS

Yes the piston moves when needed, you’re fine! I wouldn’t push it any further than that though

@@howtofrank502 haha. Thanks for the quick reply I'm literally doing this right now. I actually pushed it in all the way. Should be fine. Doubt I'm stronger then the springs. I'm doing the separator plate right now.(transgo).

Did you have any issues pushing it past flush ? I pushed mine down by hand and let it seat using spring pressure. Haven't installed accumulator yet though because I was worried it's to far down.

How’d it go for you?

It went well. I tapped the hole and used a set screw and red loctite instead of the ball set up. It drives much better. A+

Im wondering the same

Hard first to second shift not sure about late shift

You ever figure out your problem? I’m struggling with a late shift out of first as well.

@nickkane8690 my problem was related to aftermarket parts i have. I have a carbureted engine so the bracket i used for the TPI was adjustable and out of adjustment so the TPI was giving bad data.

it probably fits a different year transmission where the hole is larger for that pin. So they send both sizes to cover all

Same here, was wondering if it's ok to use 2. What did end up doing?

Just an update, I used the sonnax violet outer with a gm oem pink inner spring and my truck shifts awesome. So I had 1 spring but put back 2, was worthbit.

I did the same. I put both back in.

In the GMC Sierra forum the tech list at least 10 different symptoms and fixes for different problems it sounds like you're on the wrong video.

bishop being a newer transmission it should be relatively durable. If everything else is good, replace this accumulator and your 1-2/3-4 shift solenoids.

iput in the sonax spring, much firmer, just 1

Yes it would!

Absolutely! I just followed the manufacturers recommended process. Thanks for your comment

I'd that's all you are doing maybe the one on the separator plate should be fine and I don't think there is even really gasket there but you might need a pan gasket and if you are there you should probably get a filter kit with a new pan gasket anyway

@@james10739 thanks I was just wondering because I saw one one the internet I know about the pan my shop refuses to work on transmission we just send them away but it's one of my personal trucks

No, but a filter and fluid service might help. What is your mileage?

Andy Likhonin thanks for letting me know! Please try the link again, here it is below: facebook.com/FranksFixandFlip/

@@howtofrank502 no problem! It works now :)

Same problem and CAN'T FIND AN ANSWER ANYWHERE....

Okay got mine fixed here's what I did take a shot in the dark I studied up on the system seeing how everything switches what it takes which is I put a extended servo pin in my transmission never even slipped the first time since then and that's been about 3 months may not work for you but it did for me just the thought extended servo pin

@Daniel Hall I have a feeling i have to open the pan. I have zero Check Engine lights and that most likely means this video saved me. Thanks though 👍👍

Absolutely absolutely anytime brother you know I'm I went to man I beat my head up against the ball so long trying to figure out that issue and I've never tore up automatic transmission even so much is the pan as far as I ever got as far as ever wanted to get they are extremely intimidating but after months and months of doing nothing but research on that transmission figuring out how it shifts what causes it to ship where does it build pressure I finally ventured into pulling the pan pull the valve body off and checked everything out redone everything everything look good I mean could use a couple things I wish I had to put a shift kit in it while it's down which I have now I'm going to put in but like I said turned out to be that you know extended turbo pin it wasn't engaging the 24 band so it would you have to let off the gas to get it to shift from second to third but I wish you well my friend good luck!

Stephen christopher EBay or amazon, just search Sonnax pinless accumulator 4l60e

FranksFixAndFlip hey bro not sure what year my 4l60e came out of bought it from OfferUp to mate it with my gen 3 5.3 . The Amazon’s it eBay accumulator should fit forsure right?

Beto’s Garage Yes. 4l60E is the same overall, but if you want a nice upgrade get a 4l65!

@@howtofrank502 I have heard you can't tell the difference by the outside of the case is this true? My truck is a 2011 silverado 4.8 4 speed I'm guessing they are all 4l60e

Stephen christopher It is pretty much true, only difference really would be the way it fits against the engine. If you are putting a 4.8 4l60e on a 4.3 engine you may need a adapter plate. Other than that they transmission were virtually the same, slight upgrades over the years.

Henrri Flores hola! pasemos a 3:25 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2PV62NbfWfk.html

I don’t see an issue with that. Wasn’t worth the effort for me as it is overall low pressure, but if you have the tools handy go for it! Thanks for watching.

Yeah! tap it and perhaps use a grub screw?

What is your mileage? It could be your B shift solenoid failing, but this part is most notorious to fail in the 4L60E

One hundred Sixteen miles

Mine is v8 Colorado

I think mine is 4l60e

I would bet it’s the accumulator. Mine had close to the same mileage when it showed symptoms of failure

This is the way!

@@UpstateSCBass two factory aluminum piston and shim, better and cheaper

Could y'all please elaborate? I'm currently in the process of trying to figure out what to do with my accumaltor.

How so?

I don't get how putting two Pistons in and making less volume works especially since my truck stopped shifting out of first and on the teardown the only thing I found was the 1-2 accumulator spring was broke did I miss something??

Justin Cody Lol just hammer a “X” into the metal on top of the ball, don’t over think it.

@@howtofrank502 like on the ball or where you drop the ball into

Justin Cody Where you drop the ball into. You put the ball in the hole, press it flush (flat), then hammer a X into the metal housing the ball is inside of.

Justin Cody focus on the part where I draw my finger when explaining cross hatching. Do exactly as I drew and you will be in good shape. To make sure you did it right flip it over and try to force the ball out. If it doesn’t budge you’re good

@@howtofrank502 lol ok we all have our moments 🤣🤦🏻‍♂️
