I searched out information about my Duramax 2.8 Colorado in order to see what is inside this transmission (mine is failing). This is an awesome video to show how this transmission goes together. It would have been awesome to see the TC as well, since it was obviously damaged, maybe even tearing it apart. But still an awesome video. Thanks for the info.
Your comments about Ford C-4 sticking governors reminds me of a story. A Transmission mechanic was recalling some of the things the mechanic that taught him, way back when. If it was a Ford C-4, C-6, or FMX, and the governor was suspected of sticking, he would get the vehicle up to about 40 MPH on the road, then, try to engage it in Park! The idea was to have the parking pawl create so much rattling that the governor valve would dislodge any particles. The later mechanic would never try that, he would rather take off the extension housing, and, clean up the governor that way. ;)
Another Colorado/canyon owner here. Think I've got a blown converter, but I know you mentioned sonnax o ring kit for the valve body, in an install like this would you also recommend something like their "zip" kit?? And also out of curiosity, typically what would a rebuild of that depth costs approximately?
I have a 6L50 in an 08 CTS. I had a stripped output shaft spline and the transfer case stripped input shaft spline, both replaced. I'm getting codes P0700, P0716 and P1751. After driving a while or intermittently, I get a very hard shift, especially when in traffic at slower speeds. Have you experienced this issue before? What would you recommend?
I just bought a 2016 gmc canyon diesel 146,000 miles has 6l50 and 3rd slips at first before locking in, the slip time veries no slip to all slip to 4th depending on throttle seem not to slip with heavy throttle. Will be towing in the future and don't like fixing things twice so I've been doing some research and most common issue seems to be the check balls. I don't want to remove the trans. I'm thinking a valve body service and a deep pan would fix it. Any other service suggestions while I'm in there. Seen people say adding separate trans cooler isn't necessary as they don't tend to overheat. I did see your other video with the o-ring plug kit😉
@GaryFerraro I'll try manual mode on the highway tomorrow and check. Would that mean full rebuild, checking shift pistons, or solinoid. No malfunction indecator lights on the dash. Still watching RUclips videos here and there. As you can imagine the truck does run and drive but needs lot of service work done and don't want to tow till everything is up to 100%
Gary this was a great video. I have this transmission in my GMC Duramax Canyon. 50,000 miles. If you did your rebuild, as impeccable as it appears, would this engine just eat up this transmission/TC again? Currently truck shudders, clutches feel like slipping in 2-4 ranges, and there is a big chug when engine shifts while truck is decelerating (highway speeds).
Would you always upgrade the regulator? Would all the friction be replaced? If the shuttering torque converter is a consistent failure point who makes a better one?
I always update regulator valve (big problem with wearing out) Always replace the clutch plates. I believe the problem is the material that the clutch is made out of. So that has been upgraded, I purchase the converters from Transtar and rarely have a problem
@@GaryFerraro Seems we are all learning about these 6l50's. In todays market is a new 6l50 even worth? knowing what its going to do. Just drop the trans and have it rebuilt with upgraded plates and clutches new master kit for switch in the electro hydro switch ? and going to replace with Amsoil Dexos iv. That's what I perceive anyways.
@@GaryFerraro So I got a quote from a Local guy saying 5500.00 for the rebuild. Don't have that on hand. Now I don't know what to do If I flush it, It could make it worse. I bought all fluids from amsoil ATF was like 150.00. Should I flush it and hope for the best. or just save up for the rebuild and deal with it?
hopefully you can help me. I have a 2009 cadillac cgs with the same transmission. Problem Is when from a stop I accelerate and it feels like 2nd gear goes in twice. It feels like it kinda grabs for a moment then releases it and the grabs again but with a hard pull. sometimes if I take off fast it doesnt do it.
@@gs3188 Yes, just drop the pan, 2 bolts hold it in and unplug old one from TCM, very easy to do, Make sure you install the plastic rod into the manual valve
Old school good business. Gary is an encyclopedia we need a lot more like him.
Thanks for watching
@@GaryFerraro the knowledge and retention you have for all these transmissions is amazing. Hats off to you.
Thank you
There's another guy in Texas that also is a transmission encyclopedia. These are the types you want building your transmissions.
Your dad taught you very well these values are being forgotten now days thank you for saying that
Thank you

wow, never heard of that method , did that work?
@@GaryFerraro I'll bet it occasionally created some additional work and revenue.
Thank you Gary I was waiting for the video of the trandmission 8L45.
Had one a few months ago but it was so busted up and could not get parts, had to go with a dealer reman, then i programmed it
@@GaryFerraro I built the 8L45 transmission, I bought the parts on transtar and other parts in the dealer.
@@JosePerez-fw1zj where are you located? i went on transend ordering site and i didn't think i could get the kit, what brand kit did you use?
@@GaryFerraro Im located in los angeles California. I'm not sure what brand I used but thats where i bought it from.
Beautiful 👌
I wish I could do what you do. Amazing man! How can you even remember where everything goes when you put it together? 👏🏾
Big like for you
Thankyou

Zip kit can't hurt, should come with the o-ring end plugs, never used a zip kit myself, This rebuild with a computer runs about 4300ish
thanks for the teardown video really enjoyed it 👍.
Thanks for watching
You are correct we do have a governor problem. What makes the 50 or 45 and the E.
That is the torque rating, the 45 and 50 you will find only in cars or small vehicles The E is Electronic

Wouldn't be the first TC failure on those GM 6 speeds. LOL At least it seems he got lucky enough that it didn't damage too many other parts.
Common problem, almost every one i get in is a blown converter

you mean those huge pliers i was using

Is the fluid pump supposed to slide in flush? What is the procedure for installing the fluid pump?
if the pump is all together, it should sit flush onto the case

@@johnbene3277 On Everyone, bore plugs are very loose
I read on the net that this transmission was developed in house by GM, however watching the tear-down I see shades of a ZF hybrid. Maybe it's just me.
ZF Hybrid, which transmission?
@@GaryFerraro I guess It's just me. This one.
@@Transient901 Like a 6HP26?

Gn does the transmission from the jimmy and the colorado the same wanted to know plz if u can
what year and engine size,are you talking 4 speed trans, 4L60E

How many spline are on that output shaft?
What is the normal interval time for changing the AT fluid
every 20 to 25K miles
Why wouldn't you change filter and see what happens before tearing it down
The filter was clogged which means something is coming apart, if you change the filter , will only last a day or so before same problem,
Thank you for responding to my question
