New TSB for CDF drum, 10R60/10R80/10R80 MHT

[TimberExpy]

UPDATE:

Oops, guess this isn't a new TSB after all... and I'm not sure how to delete this post. Although Flying Wrenches' YouTube post is new, others were talking about this TSB earlier last year:

TSB 23-2250 - 2018-2023 Expedition/Navigator + Other Models - 10R80 Auto Trans + Others - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift

So the TSB Mason's referring to here is in fact TSB 23-2250:

Although we've not had any issues (yet?) on our '22 Timberline, I'm always worried about this 10R80 based on other's stories and posts in this forum and others.

No worries, pls. You will have the same symptoms eventually. lol. I even feel harsh engagement from gear 5 to 3 or 4 to 3 when the tranny downshifts on my brand new 2024 expedition. Putting drive train into 4A model can mitigate the harsh feeling, though.

Wow, even on a '24, huh?

Yes. But I don't think it is a CDF drum issue. It is either a learning mis-track or valve body issue.

So, if I'm going to have the same symptoms eventually, is there anything I can do now while I'm still under warranty? The only real issue I've had with the transmission is the clunking it does when going into gear on an incline. To mitigate this, I engage the parking brake when I'm parking on an incline. Otherwise the tranny hasn't given me any real problem.

But I certainly don't want to be "all good" during the warranty period, and then have something go to crap when the warranty has ended. I don't have an extended warranty.

You may ask dealership to check if there is any error code on the transmission. If there is none, I doubt there is anything else you could do. By the way, isn't it great if you feel nothing seriously wrong with the transmission?

SAME!!! When shifting between P or R or D on an incline, my 2020 would clunk which completely burned my mechanical sympathy. The only thing is my powertrain warranty expires in less than a year...
Don't know if I should bring it in. I have another thread asking about this: https://www.expeditionforum.com/thr...ed-do-they-all-do-the-occasional-clunk.55175/

Your post reminds me I did feel the clunk several times when shifting from P to R on my driveway. And my driveway is an inclined surface. But it's been a while since the last time I felt the clunk. (model year 2024)

This is concerning. I'm curious if the 10R80s that the factory has stocked have the TSB applied to them...

This happens with every automatic transmission if the vehicle is parked incorrectly. In the photo you can see how the parking position of the automatic transmission prevents the vehicle from rolling away.
The correct way to park a vehicle in an incline is to stop in D or R, stay on the brake, activate the parking brake, slowly take your foot off the brake and only then set the automatic transmission to the P position. This way, the entire weight of the vehicle is not on the pawl (#10 in the Picture). To drive away again, stand on the foot brake, switch the automatic from P to D or R and only then release the parking brake.
This way, your automatic transmission will remain undamaged for a long time

This is the procedure I follow every time I park even on the slightest of inclines. Watching (or feeling) a vehicle roll back and bounce on the parking pawl is like nails on a chalkboard to me.

One nice thing about the Auto Hold feature (if you have it turned on) is that when you later restart the engine with your foot on the brake, you can put the transmission into R or D and when you let off of the brake there is no 'clunk' or roll b/c the brakes are holding for you. So, at least there's that I guess. :/

That makes sense I guess, but I wonder what Toyota did differently on our 2016 Rav4 6-speed as well as all our previous Toyotas that would never ever clunk and jerk no matter how hard you are on the parking pawl.

Unfortunately for us, a simple piece of software that Ford didn't include in the pre-facelift 2020 model. The car is totally capable of it, we tried by engaging radar cruise when stopped on a hill and it would hold the car just like the auto hold feature! The electronic parking brake too!

Are they holding 10klbs of weight and capable of 400 plus lbs of torque through the transmission? Different design.

Every truck I’ve had (albeit not many) has this ‘Issue’. Cars, generally not so much.
