Project Carbon Next Gen 10 Speed Valve Body Kit

PPE Aluminum Transmission Pan info and pictures. Note this pan is for the SUV's and has the smaller end to go under the exhaust cross over pipe. Some of the trucks use a full depth pan which is a different part number. The SUV pan is PPE part number #128051300. I think this is a newer product, currently only available in unfinished aluminum.

The pan seems to be good quality and weighs in at 12 lbs!!
It has nice machined flat gasket flange with locating holes for the gasket.
Large Magnetic Drain Plug
Interesting internal baffle design that appears to allow fluid to fully drain and not get hung in the baffles
Heat sink fins on bottom area of pan
Holds 2.5 quarts over OE transmission pan
Includes mounting hardware
Also includes a small 1/4"?? threaded side port for an external temp gauge if desired. Might try to figure out a way to set up a fluid level sight glass using this port??

So today's update.

Sonnax Zip Kit and Torlon Check Balls arrived. Decided to swap out the cheap nylon check balls wit hthe Torlon Check Balls. These are overall more durable than the cheap nylon OE check balls that may start to wear over time.

Project Carbon Valve Body Kit should be shipping today. They were waiting on a spool valve delivery.

Is the Zip kit for a gen1 or gen2? I believe we have a gen2 on the 21+ SUVs. I only found a zip kit for the gen1.

Also, where did you find the check balls?

Just another indicator that these valve bodies are junk!!

I will confirm once I pull my valve body if the screen are still inside the valve body on the separator plate. GM chose to use STEEL so the screen parts come apart and then are attracted to the electromagnetic solenoids. The strands also get stuck in the spool valves as well. The word from the rebuilders is to do away with the screens and deal with any debris that should not be in the valve body passages!

One note- that video is an Allison 10L1000. Our SUVs and 1/2 ton pickups have a 10L80 from a joint venture between Ford and GM—two totally different transmissions?

@Kpwweb

You are correct that the only Sonnax Zip Kit I found was for the Gen 1 transmission, we do have Gen 2 transmission in the later models. There were some minor changes between Gen 1 and Gen 2, some in the valve body I believe, some in other areas of the transmission. But there are some parts that are similar. I kind of bought the kit on a whim and figured I would see what it may offer that the NextGen Project Carbon kit did not offer. I did a quick comparison and I think there may be 1 or 2 parts from the Zip Kit that I may consider, but I really need to get the valve body on the bench and inspect the OE parts and the Sonnax parts. Most likely an audible call as I rework the valve body.

For some reason I was unable to locate a Sonnax Gen 2 Zip kit, maybe only AT parts suppliers sell them direct to transmission shops.

As for the Check Balls, I was poking around and found them as an option. They are standard 0.25" check balls. I think I found them on ebay, but I did see them on Amazon for about $9 more as I recall. The check ball kit is Sonnax Part #10000-08. It is a package of 10 1/4" Torlon check balls.

So from everything I have learned/read/been told the 10L1000 is not really an Allison transmission. GM licensed the Allison name for the 10L1000 in the heavier trucks. The 10L1000 is just the big brother to the 10L80/10L90 and has a manual shift selector valve. I can tell you with pretty good authority that the valve body between the 10L1000 and the 10L80/10L90 are very similar. Most of the parts are interchangeable from the NextGen Project Carbon kit. It looks like the 10L1000 does not have the auxiliary electric fluid pump, the sub valve body assembly and does not have electronic shift selection, it has a manual shift selector valve in the valve body unlike many of the 10L80/10L90 units. The 10L1000 does not have the stupid Auto Stop/Start mess so this is why there are some differences. Otherwise even the valves that NextGen sells are the exactly the same and I believe the larger valve body separator is the same. The NextGen Project Carbon valve body kit for the 10L1000 is actually cheaper than the one for the 10L80/10L90 because it has 2 less valve body separator plates, it only has the single large separator plate.

I even ended up with the Allison 10L1000 instructions with my NextGen Project Carbon kit and I was a bit concerned that they may have shipped the wrong part number, but it turned out that I did get all the correct parts and I was told to follow the 10L1000 for the valve body upgrade. I think I just need to check on the bolt sizes and torque for the sub valve body to make sure I have all the info at hand before I tear into the valve body.
