4L60E High Performance PT3 - Sonnax Super Hold Servos

- In PT3 of the 4L60E High Performance series, I provide an overview of the Sonnax Super Hold servo kits for 2nd and 4th gear, assemble the servo, walk you though the installation and band clearance check. I also assemble the 1-2 accumulator using the pin-less accumulator kit from Sonnax.
For those installing this kit while the transmission is in the vehicle, you will want to achieve .075-.125 of servo travel. This will require grinding on the pin - Sonnax purposefully makes these pins too long so that you can grind to fit.

👍 Great video. You make this simple. God Bless.
Thanks, you too Al!
By far the best install video I’ve seen. Thanks!! The instructions for the sonnax kit are not that detailed.
Thank you for the kind words, Brian!
Thanks Nick for your reply!
Great quality and lighting really enjoy your work excellent video Nick !
Thanks again, Doc!
Wow glad I watched this before order parts , I was going to order both servos and the pin but it appears to be more I thought .
They are getting expensive and usually aren't necessary unless doing some serious heavy towing/hauling or racing.
EXCELLENT! Thanks
I have a full billet servo for my 700r4 and it doesn’t have that spring and plate and snap ring involved in it at all. I put it together exactly like the instructions show and the diagram and it seems as though it would go in but there is no spring action
Hi Wil, what servo are you installing? Sounds like the Superior Tech servo but you can confirm or deny.
Hi Nick, I have a question, is there a lot of difference in the shift quality between the .490 and the .500 boost valve? Thanks!
Hi Doug, assuming you held everything else equal and just swapped diff ratio boost valves, seat of the pants felt difference would be minimal IMO.
Great videos!! Just curious, how do you get the tires to bark?
Thanks, Marc!
Get the tires within line of sight of a mailman and they will bark their heads off, haha.
All kidding aside, an aggressive enough shift calibration will do it but it's not as easy in the 4L60E/700R4 due to the big ratio drop from 3.05 in first gear to 1.63 in second.
Since the band wiggles a little bit without the pump installed, Would it be more accurate if the pump was in place? Or will it not make a change at all?
HI Bad Drivers and car stuff, good question...Yes - having the pump in would provide a more accurate read on band clearance though in my experience the difference is not significant enough to completely invalidate any measurements taking place pre-pump install.
That said, I will be doing a band adjustment video where I walk the viewer through the process of measuring servo travel, checking/adjusting band clearance and will have the pump installed for that video...Figure about 2-3 weeks until it's on the channel.
Thank you for watching!
@@nickstransmissions Awesome thanks. I'm pulling my transmission next week to do some other upgrades and this is one of them. Thank you very much for the video and the reply.
You're welcome, man. Feel free to ask questions as you're going through yours.
One rec I'll make (assuming you're not already planning on it) is the Alto Power Pack (HE or Alto Reds, Kolene Steels). I've been using that a lot lately and it's a nice upgrade to the factory six-clutch 3-4 pack.
@@nickstransmissions I've been running the Alto Reds with Kolene Steels and the Sonnax backing plate kit since 7/23 and I've been happy with them. While I have the transmission out I'll check them and change them since I put them through a lot of abuse. I'm running all Sonnax parts throughout the 4L70e and after I install these Servos I should be good for a while. The only thing left is the Smart-Tech Input drum and I haven't justified that yet for my power level.
Good deal, man...Should be a solid set up. I sometimes use the Sonnax forward drum reinforcement kit w/billet piston for anything that will see heavy duty or high RPM use but where the Smarttech drum is either unnecessary or out of the customer's budget...Cope Racing also makes a 4L79 drum that has 9 frictions in it as well, though I've never tried it.
Let’s just slam and slide everything on a metal table 🤪🤪🤪
You didn't know that slamming parts on a metal table increases their strength and consequently, the transmission's power handling capacity by like 10x? It's by far the best way to beef up your transmission!
😂 I have watched many videos like this and they all do it!
what is the size.of the washer. thickness. It.didnt come in my kit and it's too late to complain
Not sure on the size but you can call Sonnax and they should give you the dimensions. When you can, select the menu option corresponding to their customer tech support group.
