Stripped Torx, now what?
 

I attempted to change my transmission fluid and filter this afternoon, and of the 24 odd torx, I stripped 2. Anybody have any idea what I should do now?

I used a T27, would going to a slightly larger size (28, 29?) work? I have a T30, but it was too large.

It's really too bad they stripped, because I'd be done by now if they hadn't!

After you get some sort of bit to fit into it, you should try using an impact driver. NOT the power ones used on wheel bolts, but one you hit with a hammer, driving the bit into the screw, while simultaneously turning it a small amount (make sure you set it to undo, not tighten). Picture below. Mandatory tool for Japanese motorcycles with lots of Phillips head screws in the side cases. If another Torx bit fits, fine. If not, use a hacksaw to cut a slot in the head (yes, it's painful). If none of the above work, then you are faced with drilling it and using an Easy-out screw extractor, or something similar.

Impact driver! Duh, why didn't I think of that?

I was hoping to reuse the Torx, I guess not now.

Since I've used it so many times I vote for the drilling it and using an Easy-out screw extractor method. Just make sure you get the best extractor you can find.

Before you drill, some times an allen head will fit into a striped out torx head. And like JCL suggested a hand impact is ideal for this job.

Let us know how it turns out.

So I see that Bavarian Auto doesn't carry these torx bolts. Anybody have another good source?

Try ecstuning

I just ran into the same prob recently. Took a dremel tool, cut a slit across it and used a large flat-head screwdriver to turn it loose.

Dremel should work beautifully. I have used it in a similar scenario.

A screw out is ok but I found myself cursing more when that doesn't work. What I find works a hell of a lot better are bolt outs. I just did this yesterday when I stripped a t30. These bolt outs are usually tempered steel but I have cobalt ones that are tapered and fluted. Bolt came out without a problem. I think sears sells a good set in a pinch! Essentially the bolt out grabs the outside of the bolt and not the inside which is already weak.
