I tried to adjust the tranny bowden cable but the threaded end was stuck tight to the ball socket end. The threaded end cheerily sheared off when I tried a bit more. I did yell `no please donītī but it fell to deaf ears

First I thought I needed to replace the entire bowden cable, but then I found a screw on repair end in PET, which seems perfect. It just costs about $75 bucks. For a simple threaded end. I have a relatively high tolerance for Porsche prices, but this is ridiculous.

So I looked at replacement ends online, most found at bike shops, these seem to have to be either pressed on or soldered on. I can either try to `pressī on a new end by squeezing the hell out of a pair of cable pliers, side cutters, or something like that, or I can try to solder it on.

Anyone have experience in repairing bowden cables and willing to share some helpful does and dontīs?

PS. is it possible to drive without the bowden cable for a short while?

they make a collar that has two allen screws. you can slip each end of the cable onto the collar and tighten down the screws and walla....

Get a threaded end with the correct thread. Clean up the cable end - fraying etc. Silver solder would be preferred for strength, if you can do it. Get the cable end soaked with solder, file it all clean so it will go into the hole in the back of the threaded end. Insert cable into hole with assembly vertical, thread end down, fill with solder. If you have an end with grub screws coming in from the side to lock the cable, fit these before filling with solder.
I think driving without the cable will just produce early up changes, as the box wont know how much pedal you have applied.

I made my own. I will check for it as I have replaced my cable during TT rebuild. Just a collar that screws on to threaded ball cup end with two set screws to hold cable.
I found it, would you like me to send it to you?

Thanks for the responses.

I tried soldering, but since the cable is stainless steel it doesn't flow with a normal (20W) soldering iron.

Luckily no such thing as a unique problem on rennlist. Thomas, if you don't need the collar anymore, then I would love to have it. Thanks!

take a bolt of the right thread pitch, and a short part that has no thread.
Cut off the head a drill a hole in the end where the head was that is JUST bigger than the cable.
Insert cable and with a butane or propane torch heat it to run silver solder into it.
Once cool reassemble!

I did that but with a 20W soldering iron. Guess it needs much more heat to flow. Are there any health issues when soldering with gas e.g. using brake cleaner etc. Anyway, Thomas graciously offered to send me the collar he made when he had this issue.

At least he didn't mention the most dreaded string instrument-viola!

There is a lot of difference between silver soldering and normal soldering. Silver soldering is actually "silver brazing" and requires getting the parts much much hotter, usually approaching "red" hot, depending on the melting temps of the silver solder you have. The good news is silver soldering is many times stronger than regular soldering, and it will adhere to stainless too. It can be as strong as 60,000 psi yield.... the bad news about this approach described in the thread is you may well have a bowden cable that is now too short and will require an extension between the ball socket part and the adapter that is brazed on the cable....I had to add a 1/2" spacer to get shifts correct.....otherwise the transmission would never shift into 4th unless you completely let off the throttle....

Silver soldering is a neat process I have used for along time for making certain parts...it comes in handy very often for the sorts of things I do...but it does require a good hot flame....able to heat up the parts to a cherry red, and a prope flux is needed also....welding supply shops will have all you need and will most likely give you some tips on use too...
