2006 f150 screw with 113000 miles. I had the transmission completely rebuilt only 11000 miles ago. Last week I hear a dreaded whining sound and my mechanic says it's the torque converter and it's unfortunately our of warranty. Metal shavings completely infiltrated the entire system! Should a converter go out that soon after a rebuild? Based on preliminary research these things last forever. It just doesn't seem right. Gonna run me 1500 bucks to fix everything.

 

I would likely say you got a defective transmission OR the shop screwed up and didn't replace a contaminated trans cooler and/or used the original torque converter to cut corners.

Since you say you are out of warranty, I would consult some more shops.

Did you physically see the metal shavings, or are you going off what your mechanic says?

 

I thought most transmission rebuilds have a 12mo/12k warranty or better?

 

They are supposed to -- unless you used old parts, like the torque converter and trans cooler.

I just helped a buddy do a transmission a few weeks ago, and it had warnings on the paper work, crate, and tags on the transmission warning that using old parts automatically voids the warranty.

I have also seen some in addition to that warning, it also says that a qualified mechanic/business needs to install it for the warranty to be valid and they'd only honor it with a receipt with mileage out.

But going back to OP, if they are still within warranty, but they did use old parts, it's not out of the question to contact the manufacturer to see what they'll do. They might bargain with shipping costs; basically whatever it costs for freight to and from, the OP can pay for. I've see scenarios like this, but I've also seen the opposite where it's firm no matter how nice you are... basically what I'm getting to, is ask first. It can't hurt.
