My question might sound dumb but do i need to replace all accumulators in the unit to pinless or can i just replace the 1-2 accumulator since others are working fine.
What would cause my 2001 4x4 Suburban to shift super hard after descending off of a big hill? It will slam through gears until I shut it down and let it cool off a while.
i see people put the sonnax 4th accumulator piston in dome side down with spring, and then put the spring in and dome side up toward the vb plate. which way is right? or does it matter?
@@mikehensley3486 so does it make any noticeable difference for 4th gear holding power or just shift quality? I’d like this thing to hold 4th gear better.
I was thinking of upgrading my 1-2 accumulator but it looks easy to do the 3-4 as well. Can I do both without removing the valve body? If I'm on my back on the ground, how would I hold the check ball up? Assembly gel? vaseline?
@@writtenpieceopaper1 I did the whole bottom end, including both accumulators and the ceramic balls. Working great for a couple of years. Also did the corvette thingie on the side. Pumped out the fluid with the engine. Now I think I only needed the front accumulator which woulda been real easy. Because reverse was working fine and when I disassembed the forward accumulator, you could see it was not moving smoothly. Easy R & R but I did the full monty.
@treslongwell1332 thank you. I might as well do all of that too. My 07 silverado is right at 155k miles. The fact it lasted you years is great motivation
Where can I buy that sanding stone you use on the case to valve body plate surface? I am not sure how coarse or fine it should be for just assuring flatness of aluminum valve body and mating surface.
Is the first ball you jam down in the hole supposed to pop out the back side and go into where the valve is it's like hanging out a little bit if I look where the valves slide back-and-forth behind that
The wave spring at 4:18 I ordered the sonnex pinless kit from Amazon but didn’t came with that wave spring my question is it safe to use it with out the wave spring??? Thanks
I have a hummer h3 2009 with 4L60E transmission.. When i put to D it takes about 2-3 seconds delay but R engagement is fine. Once it's engaged to D, driving is fine no delays and slipping..please help me in this matter...Thank you
I would recommend getting a pressure gauge on it. It could be warning signs of a forward clutch failure. A pressure test will give the direction to where the problem is withing the transmission.
So I can use the older housing on my 01 then? I don't have the waved spring or the spacer so I wanna use pre 01 style housing if I can? Need to know asap thank you.
Im currently doing this on a suburban and the forword piston is WAY tight and when i put the little balls in they went in no problem. I dudnt need to jam them in. Is that a problem?
I have the same accumulator housing you showed in this video on my 01 transmission I have a purple outer sonnax spring a couple inners and a couple other stock outers and a enhanced performance 77704s spring not sure which inner and outer to use? Any advice?
What about if you are installing transgo hd-2 kit with the sonnax. i want to put spacer for a 1-2 shift firmness. Im be add 2 spacers for very firm shift. I want to know the correct order to install it. Please and thank you
That's not something recommend doing. If you want to mix that part that's entirely your decision and I wish you the best of luck with. Sorry I'm not much help with that one.
Directions say dome goes case side. Perhaps the directions are different based on full shift kit vs stand alone part? Does it really matter what way it goes in?
Just had a 4l60e rebuilt and have went through 2 torque converts from the guy that rebuilt it but have the same issue every time. I get a very slow engagement when I go into drive. As if it’s almost not in drive until I reach around 1300 RPM and then it kicks in. Same for reverse. Then in OD, the RPM fluctuates 200-300 every few seconds unless I’m above 60. Any ideas what I can look at??? I’m tired of dealing with this guy.
@@expressautotransmissiondav4207 I have no had a pressure gauge hooked up to it. It’s a 97 model with PWM. The guy said he checked pressure on everything, not sure if that’s possible without it being in the truck.
@@expressautotransmissiondav4207 could I have that done at an auto parts store? I have the valve body taken off this morning. The forward accumulator was not replaced and seems worn out at the pin. Could this affect the engagement of 1st?
Hello ... Can you tell in more detail here in the comments, what is the iron plate for, and what does the new valve and spring do from this Sonnax set?
The separator plate is to change direction of fluid flow. And the valve with spring and plug change the apply for lockup and regulate the apply pressure.
will the lock up spring work on a 03 4l60e. I have a kit from transmission bench which has that spring but states it's only for the 95 and below years. so I have to buy the sonnox valve.
@@expressautotransmissiondav4207 I was going to do the sonnax pinless piston just wanna know which spring would be best for a possibly firmer shift if it doesn't firm up well at least I know the plastic one is outta there.
I'm confused. You plastering no spacer all over the screen yet the instructions clearly say for 01 and later to use a spacer. Later must mean newer then 01 cause right under it it say 94 to 2000 doesn't need that spacer. You said your trans is an 03 so that would mean that it does need the spacer given what the instructions are saying. So please explain why the no spacer all over the screen.
I'm sorry for the confusion during the video. In the instructions it cals for the spacer to be installed in 94-00 accumulator body's. I worded it incorrectly during the video, our transmission was an 03 but had a 94-00 accumulator housing thus why we installed the spacer. Again very sorry for the confusion of that.
@@expressautotransmissiondav4207 LOL. You got it wrong again. You said that "In the instructions it calls for the spacer to be installed in 94-00 accumulator body's." and that's wrong haha. It's the other way around, 94-00 doesn't need the spacer..... but you said yours is the 94-00 style so I got-ya now, all is forgiven. 🙂 I do have a question for you though. Is there any advantage to using the 94-00 on a 01 and up trans? are the stronger or better in any way? thanks in advance for your answer.
I don't know of any technical reasons why it's better this one came that way is only reason it left that way lol and thanks for the comments I appreciate it

In my experience yes. The things to watch for are if the vehicle is retaining dod if it is then this kit should be a supplement to a sure cure kit without on off lock control change. If you have some specifics about your build I can answer more thoroughly

Great video, very thorough and detailed, nicely done.
Looking forward for part 2.. 😃👍
It might have already been mentioned but always replace or at least check map sensor and TPS. They can report back the wrong load calculations.

The instructions say to have dome towards the case. I noticed this one the dome was towards the Spacer plate.
So what way is it lol? My original was towards the case.
I ended up putting spring in and putting piston up against vb. Seems to be doing fine
@@mikehensley3486 so does it make any noticeable difference for 4th gear holding power or just shift quality? I’d like this thing to hold 4th gear better.
A ball doesn’t go into the 3-4 in place of pin?
Did you find out I’m wondering??
Did you need to block the center hole with the pinless 3-4 accumulator?
That’s what I want to know!?!?!

Sorry, I see where you answered the question below.
What is that stone you use to do the VB surface of your transmission?
It's a fine and course stone. I purchased it from A&Reds transmission supply. They work great for valvebodys and cases.
May I ask why people put the 4th accumulator backwards? What’s the benefit of that ?
It's cancels the accumulation of 4th also cuts down to amount of leak in the 4th clutch circuit.
Is the first ball you jam down in the hole supposed to pop out the back side and go into where the valve is it's like hanging out a little bit if I look where the valves slide back-and-forth behind that
Yes.it will potrude from the back of the hole once driven in
@@expressautotransmissiondav4207 that does not interfere with the valve the slides right there
The wave spring at 4:18 I ordered the sonnex pinless kit from Amazon but didn’t came with that wave spring my question is it safe to use it with out the wave spring??? Thanks
Absolutely the wave spring is only included in the performance pack.
Can this be installed while the transmission is still in the truck?
I have a 2000 s20 and it keep going in and out of lockup what could it be
this would be a fine video but the instructions you gave for the 3-4 accumuator is upside down compared on the sonnax instructions
you can put them in either way the way he did it it will be a little more firmer

@@expressautotransmissiondav4207 A real live complete 700r4 build? or is it really all the same as the 4L60E? Is it possible to contact you? Thanks
I can do either and absolutely look up our page name for baxter springs ks
why did you install the 3/4 accumulator dome up?
Per the instructions of the sonnax kit.
www.sonnax.com/parts/2520-pinless-accumulator-piston-kit
Directions say dome goes case side. Perhaps the directions are different based on full shift kit vs stand alone part? Does it really matter what way it goes in?
It's does for accumulation purpose when it's upside down I believe it acts to hell seal the circuit from cross leaks

My 4l60e was rebuild and the torque converter wasn't replaced and now I have a shutter between 45mph and 55mph. What should I do?
That's a tough one. Do you have a local shop you can trust to check it out.
@@expressautotransmissiondav4207 no! I am thinking about pulling it and check it out for bad parts in the rebuild.
Ahhhh ok
Did you ever find out what caused the shutter? I get a similar shutter.
So is it ok if my piston sits alittle lower than the housing? My OE spring let's it sit lower than how yours looks I have a 2001 4l60e.
Yep yep
So sir I'm wondering for accumulator piston install is it firmer the spring softer the shift and lighter spring tension harder shift?
Unfortunately there's a bit more than that to it.
