A new service bulletin has been released for the 2024 Chevy Traverse highlighting an issue related to the vehicle’s transmission. This time, the issue referenced can result in DTC (Diagnostic Trouble Code) P2817, which may be triggered as the result of a damaged turbine shaft seal within the transmission assembly. The problem has been documented under Bulletin No. PIP6005, published September 12th, 2024, and applies to several GM models equipped with the GM eight-speed automatic transmission​.
According to the bulletin, the root of the problem lies in a damaged turbine shaft seal, designated as seal 548, which is responsible for maintaining a tight seal within the torque converter. This seal may suffer damage during installation, leading to potential leaks or failures within the transmission. Notably, this seal has transitioned from an O-ring to a Z-cut square Teflon design with the latest generation.
To address this issue, affected vehicles displaying code P2817 will need to have their transmission removed in order to access the turbine shaft seal and torque converter. Both the torque converter and the damaged turbine shaft seal will need to be replaced. This repair is covered under GM’s Powertrain Warranty, with labor times detailed in GM’s service documentation for precise repair guidance​.
This new issue follows a previous bulletin published in June, specifically Service Update N242446290, which also identified a transmission-related problem in the 2024 Chevy Traverse. The update published in June highlighted on an out-of-spec clutch backing plate retaining ring and clutch piston retaining ring, which requires the replacement of the clutch piston housing at GM dealerships.
The 2024 Chevy Traverse marks the debut of the crossovers’s latest third generation. Motivation is derived from the turbocharged 2.5L I4 LK0 gasoline engine, which is rated at 328 horsepower and 326 pound-feet of torque, pairing with GM’s eight-speed automatic transmission. The Traverse rides on GM’s C1 platform and is manufactured at the Lansing Delta Township plant in Michigan​​.

Yet another one escaped half-baked.
I just got my 2024 Traverse back from the dealership after 4 weeks from the first Transmission service bulletin concerning the snap ring failure. Now I have to be concerned with a Torque Converter! Come on GM….get it together!
FFS what the hell is going on with gm? Cant have fresh models being recalled for avoidable issues like this…
Only applies if your vehicle has the related transmission error code. 90% or more won’t ever occur. No recall as it’s a rare occurrence. If you check engine light comes on, then you’ll need to spend 2 hours at a dealership, and no dollars.
GM is at least being proactive, unlike Toyota who is having to retroactively replace every tundra engine.
Precisely why I avoid first year models
Yes. Why I bought a 2023 with the V6 and 9-speed transmission. The writing on the wall for the 2024’s was 2.x Turbo and an 8-speed. No thanks.
Why did GM dump the 9-speed again? Wasn’t for the benefit of the consumer.
It is the 9 speed. It’s more like comparing the 4l60 to 4l70 transmissions from 2 decades ago. 90% of the parts are the same, but one has different valves and clutches. The 8 speeds deleted 4th gear???? Which was rarely used,Which removed a clutch allowing for beefier drums, allowing for more torque from the engine. Put the two side by side, you can’t tell the difference unless you know the external RPO code stamped on the side.
Seriously!! Get rid of the 8 speed!!! all units should have the 10 speed
Not the same vehicle, they don’t have a FWD ten speed, only the full sizers do.
Always something with GM Transmissions , very unreliable now, they used to be rock solid..
Yup more 8 spd junk, just dump the 8 spd already. The 9 speed 2023 worked great why would you change it to the 8. I am sure it was over a few $ saved knowing gm.
This 8 speed is basically the 9 speed with one less gear. Do some reading and you might understand this. Its not the same 8 speed in the rear drive vehicles and for 2023 that has been fixed. I have no issues in my 2023 colorado with the 8 speed transmission. This 8 speed that use to be the 9 speed is related to the 10 speed but for different purposes.
Where is the tranny assembled ?
With the hp and torque of the engines mated to the 9FWD, it was rarely, if ever, in the top gear. Converting it to an 8-speed saved weight, complexity and cost. All without sacrificing drivability or efficiency. It was a smart move. A move Ford made on day one (they never produced theirs as a 9-speed).
A cut seal is an assembly issue and not some fatal design flaw. Overall, it is a very good transmission.
I have a travserse 3.6v6, and it’s in top gear literally 90% of the time. It’s in top gear driving light at 60 and all interstate speeds. What’s really surprising, is when on dirt roads or driving around town, dropping it into manual and it downshifts into 4th!!!! So at 35mph I’m already in 5th, 6th. That’s lots of lower gear ratio for when I’m towing/off road.
8 speeds seem to be cursed.
Jesus, I hope they figured everything out for the 2025’s…my Z71 TPW is this week
