I dropped the truck off this morning for the K1 Snap Ring Aisin issue

[Steve_Cornell]

The truck now has 25500 miles on it and I just completed a 9000 mile trip of which 6000 was pulling my toyhauler and grossing 30,000lbs.
The truck has not had any issues and I "almost" hated to have the K1 CSN done but my luck it would go out the next trip if I didn't

Curious how long it takes.

I haven't gotten a letter, so assuming my Aisin build # is within the ones they think is ok?

I’ll post an update when I get it back, probably a couple days.

What was your serial number on your trans?

The 'Book' says 10 hours, and once all of the parts came in mine took about that long. Spread over 2 days, of course.

Mine was a dreaded September '22 baby as well. My guess is that it was only a matter of time before that snap ring failed. You have peace of mind, now. At least as far as the K1 is concerned...

Gotcha. Yours is older than mine. My truck was built mid July, transmission failed with under 6k on it. Replacement tranny has a serial number putting it in December. Curious as to whether mine would be included with the new trans in this service… was just going by mileage, as my truck now has 21k.

I picked the truck up today.. I had dropped it off Wednesday morning and it was finished up this morning.
They also did the PM sensor and grid heater while it was there.
I only drove it home (about 10 miles) it seemed to shift a lot smoother but probably just my imagination, we'll see on the next trip.

Do they replace the whole transmission or the k1 assembly?

Just the K1 assembly as per the CSN 71A recall unless the transmission fails then they replace the transmission.
