Exclamation Keep An Eye On Your Transmission Case

As some know I had cracked transmission housing right out of the box. Not to beat the dead horse and yes Ford made EVERYTHING right.

But when I was looking at the old transmission's crack in the case which was about 2-2.5 inches long parallel (horizontal) to the seam. It was at the 10 o'clock position when looking from the back forward. As we were standing near it another technician that just spent the previous week in 6.7 school said they were informed that they are having problems with transmission housing cracking due to the housing not being strong enough for the higher torque of the 6.7.

I was not in the class and taking the word of the tech. I know there are a lot of trucks making a ton more power than ours but never the less this is what they are teaching in 6.7 school. So in the meantime keep an eye on the garage floor and bottom of your trucks.

Lets hope this is not a big deal.

What ever happened with your tranny? Did Ford replace the whole thing or just the case?

They replaced the entire transmission... but it wasn't without a fight. It was very stressful after spending all this money. I was actually thinking about trading it in with 1,000 miles on it, so glad I didn't (as of now).

I've got four at work I'll have to keep an eye on. Funny how Ford torture tested these things for a "million" miles in the most brutal of conditions...then had them field tested by heavy use companies...then as soon as they are available to the public...BAM!! Torque is too much for the trans case. How could they have ever known, right?

So certain are you? Hear you nothing they say, Master Yoda?

Let me help you...see the quote below from the original post.

I'll interpret it for you too. Sounds as if Ford Technicians at a Ford training were informed that they [meaning Ford] are having problems [plural meaning more than one] with transmission housing cracking due to the housing not being strong enough [the issue] for the higher torque of the 6.7 [the cause].
