So the 7CS kit for the 60e instructs to use that plug included and replace the checkball. Some locals have told me that particular piece caused their 3rd gear to fail prematurely. I understand that some guys use a plug and then drill the edge of the sealing area, around a .035” hole. I believe the point of this is just to prevent centrifugal apply.
my question is,
will the use of this plug provided with the kit give me issues? I have always used the springs but have never used the provided plug with the bleed hole . I recently built one and I’m debating on pulling the plug and just reinstalling the capsule back again if it’s gna give issues.

 

what rpm are you shifting at?

yea the general consensus here is to not use the Transgo orifice and just keep the checkball capsule. I don't think it's the end of the world if you end up using it though. I know I have a bunch of units where I installed it long before finding this message board

 

I have used that orificed plug with success for 20 plus years. I just did a fresh-up service for one I built 7 years ago. It had developed a converter whine. Customer wanted to freshen it up while it was out for the new converter. It had all the springs in both retainers and the orifice, It had 8- Raybestos GPZ 105's & 6 .077 non kolene steels. They looked like they were installed 6 month's ago.

 

Around 7200 rpm
and why is the consensus here to not use it? What’s the thinking behind it?

good to hear tranzman thank you for your feedback always have good info

 

Alot is just a matter of preference and experience. Each to thier own. Many questions you ask of builders you will get 50 different perspectives some wrong many right.
I have done it both ways and both ways worked fine.

 

I'll keep this short and sweet
The idea to move the bleed orifice is an ok idea
Adding a 2nd bleed orifice to an already starved circuit...not a good idea

The orifice will work for some lower hp or lower rpm stuff but it's not the ideal for a unit that truly gets abused.

 

Ideally a Bleed Orifice and Stiffer Springs used TOGETHER (with the Check-Ball Capsule in the Input-Drum) is what you would want to help prevent a Clutch Pack from applying at high RPM.
I agree that Drilling a Bleed Orifice is not ideal for the 3-4 Clutch on the 4L60E.
I also do not like that the TransGo Part does not use a Check-Ball (Like the Stock part does).

I would prefer installing a replacement Stock Check-Ball Capsule in the Input-Drum, or even the Superior Transmission Version.

I have also had good luck with even stiffer Springs (slightly shorter) and a custom Thicker Steel Cage.
This works with the same process for the forward Clutch...
But I do not like the Forward apply feeling with a Lower Stall Speed Torque Converter.

 

I actually have to read all this crap in my Notes now...
It's really frustrating.

My brain just can't retain nor process this stuff anymore!
Don't lose your Mind guys!

 

Another Option is to remove the Check-Ball Capsule, Drill, Tap, and Plug with a Set-Screw...

Then Add a Universal Check-Ball Capsule in a new location (Drill and Press-In/ Install).



In Older Transmissions where Hard Parts can be difficult to find...
Often the Drum or Apply Piston that is Obtained has a Check-Ball Capsule when one is not needed.
Or the Opposite, the Drum or Apply Piston does not have a Check-Ball Capsule, and one is needed.

It is common practice to remove one and plug with a Set-Screw...
Or to Install a new One.

 

at least you took notes!

 

I have enough notes on Building GM Power-Train Systems...
(Building all of the following: Engines, Manual Transmissions, Automatic Transmissions, Transfer-Cases, Differentials, Super-Chargers, Turbo-Chargers, Nitrous-Oxide Injection, Ethanol/ Methanol Fueling, Alternators, Power-Steering Pumps, Hydro-Boost Units, Carburetors, Mechanical Fuel-Injection, Distributors, Magnetos, as well as all of the Wiring Harnesses/ Connectors from scratch, and Control-Module Repairs).

I could fill enough Books to look like the Encyclopedia-Britannica!
LMAO!


When you start having health issues that could kill you at any time, you think about things that otherwise would not have been on your mind.

I wonder if anyone would Organize and Publish all these Notes before I "Kick it".

 

You've got my email
I'm compiling a couple build books. Not only that cover some of the mods/tricks. But with accompanying reasons/theory behind the modifications.
I'm only just begun on 60e and 80e but they're a labor of love that's coming along.

 

I absolutely have your E-Mail!

I have honestly been so impressed by you over these years and continue to be further and further impressed...
I would actually leave whatever I have left to you, when the time comes.


I would love to see you release some Books!

I am also looking forward to whatever you have for me, regarding our last E-Mail!!!

 

From experience imo a fresh checkball and capsule is the way to go and aids in release. The plug will work but its best to stay oem on this subject.

 

Thanks everyone
trans shifted great

 

Do you intend to publish these books when finished. I would be willing to pay a premium price for those book.

 

this..

 

Never thought there would be enough interest to even consider a publication.
If anything it would be a simple printing, not something like the cliff ruggles book or others similar to that

 

If you ever make them available for sale, print or digital I am very interested.
