- In this video I interview Jack McGee, Owner of Jacks Transmissions and he discusses the differences between CBA and DBA GT-R GR6 Transmissions. There is a long lasting debate between GT-R owners about the longevity of CBA GR6's vs DBA. Jack discusses 3 differences in the CBA including Clutch Seals, ETS Gear Splines, and Synchro Sleeves. All GT-R owners and potential owners should checkout this video.

CBA 2008-2011
DBA 2012-2016
EBA 2017-2020
2020 to now is technically EBA
Some purists disagree with the EBA term. Personally, I like it. Thanks for commenting.
The great content keeps coming, great job Darrell😀
Thanks so much Kevin !! I really got lucky with the Jack interview. Hoping I can get some additional experts in my vid's to share some additional knowledge !!
So grateful I live 40 minutes from his shop. Gonna make getting my trans bulletproofed that much easier. 🤘
Sweet !!
Excellent video, very informative, picked up some new info about the synchro sleeves.
Cool.. Thanks for watching.
Great stuff, learned something new for sure!
Glad to hear it!. Thanks for the comment, and thanks so much for watching !! I have a new one dropping on Friday. It's going to be awesome. I'm also going to be interviewing a tuner !!
Thank you for this video. Very informative.
You're very welcome! Thanks for watching and commenting !
Great video, thanks for this!
Thank for watching and the compliment. Having Jack share his knowledge makes it really easy !
Great informative video. I just picked up a spare CBA trans and likely get few things done.
Nice !! Jack's the man !! Good idea to have a spare for sure!! That's awesome !!
Love the vids
Thanks so much for watching. A couple more from Jack.. Then off to do a Bell Housing video and then maybe a behind the scenes with a Tuner.
This is awesome. Thank you.
Thanks so much for watching. So awesome that Jack took the time to explain the differences.
@@The.Garage.Studio I agree. It's fantastic. So much knowledge in this man.
Question, is there any videos where he discusses the limits of power or torque on a standard gearbox of what needs to be done to keep them alive when tuned and roughly how much
I recall some old forum threads where Jack mentioned that he had a pre-emptive solution for the synchro sleeves. It sounded like he installed some sort of internal stopper inside the valve body, which then reduced the load on the sleeve stopper, and that this could be done before it all goes south
Hm.. interesting..
Good video😊
Thanks 😁.. Really appreciate the view and the comment !!!
Great video. Thanks. I am too a little confused when Jack started jumping around talking about the synchro sleeves, ETS gear and then the clips. So is he saying for the CBA, you should definitely update the clips to prolong the life of the trans? Or should you also change the synchro sleeves and ETS gear? I guess the answer is "yes change all of them" but just want to clarify when he started talking about the failure that would render the trans useless (@10:05), is his talking just about the TSB clips or the clips at the ETS gear?
Yeah, it's a little bit confusing and i'm not a gear head. But he is definitely not talking about the typical TSB clips replacement. It's the clips for the ETS gear. Hope this helps. You could also give Jacks Transmissions a call to get clarification.
At the 10min mark he’s talking about the cir clip that holds the ets drive gear on the end of the output shaft. Like he said if you ever have the front cover off the trans that clip is right there in your face and might as well upgrade it.
My advice is change over everything in a cba trans to dba except the synchro sleeves, the labor required for that just doesn’t justify it on its own. Save that for if your building a trans with an entire new gearset. (Hence why cba cores are usually 1200-1500$ more to build than a dba core)
I have a 2014 R35 which already has a DBA but I've been wanting to pick up a used cba which I would like to build and keep as spare, but I do see that it costs around $1350 extra to convert to a DBA, my plan is to do the basic 1st gear upgrade, clutches and baskets
Sounds like a plan.
WHEN I REACHED OUT TO JACKS FOR ADVICE ABOUT A LEAKING SEAL FROM THE TRANSMISSION HE WAS OF NO ASSISTANCE. unlike Shep TRANSMISSION WHO WAS NOT LACKING WITH ADVICE
Thanks for sharing.
Just wanted to point out that the pictures for the synchro sleeves and the splines on the shaft for the C clip are in the wrong segments they are switched.
Thanks for pointing this out. Really appreciate it !!
What clip is he talking about 9:58 ? Anyone got any relevant links where I can look more into that specific clip etc.
Thanks
Jack sort or talks about clip/spline in the same sentence. So I think it's the same thing. I would however reach out to Jack directly. You can email him at: shop@jackstransmissions.com
@@The.Garage.Studio appreciate the response. Do you know by any chance if he is talking about the tsb clips?
did you end up posting the advice to tuners video with jack? i cant find it
I did. Here you go - th-cam.com/video/N99YiJLWk_A/w-d-xo.html
Legend thanks
@@bentles You bet..
Hi, do you have any info on how the 2 filters that go in the transmission? Where to buy them and the exact model#? Thanks
Reach out to Jack. He'll hook you up. sales@jackstransmissions.com
@@The.Garage.Studio got it thanks 🙏. I went to his website and all the products are there. Makes it easy!
Keep making these gtr videos!!!!
You bet!! So much more content to create on this beast. I'm hoping to get a tuner.. to do a a "behind the scenes" tuning for a GT-R.. That would be cool !!
what does he mean by shock? is this when you use launch control?
Anytime you "shock" the drive trane. Meaning a violent launch, or when shifting gears, and it's violent (i.,e lots of wheelspin). I know we like wheelspin, but with AWD cars, that should not be the goal if you want longevity.
He’s rebuilt over thousands of transmissions
Jack is awesome !!
TLDR: if you dont have deep pockets, dont buy a GTR.
True.
