this is a high speed glider launch winch. Drive is actually 1st 2nd and 3rd auto shifting, when it gets to 3rd we want it to stay there till the launch is complete, at present it is changing down and breaking the cable as the speed has to reduce higher up the launch, when we still need a strong pull.

not sure what you ask . it slips outa 3rd ? shifts down after gets to 3rd ? snaps kik down cable ?
A GUESS! adjustment on cable improper,too much tension can snap cable ? get specs to ensure correct fit .

Wait a minute, this is not in an automobile, this is pulled out of a car and put in some sort of machinery?
Think about when cars downshift.
- If you hit the gas (why would your tranny think that?)
- If the vehicle slowed down (i.e. output shaft slowed down)
If the output shaft is slowing down because that's a part of your cycle, then maybe you need to look at your gearing ratio (pulley diameters, whatever) so that you can either keep the output shaft from slowing down, or move it into a range where the tranny won't want to downshift.
Or maybe you just need a stronger cable. To maintain the same power when speed slows down, torque (or tug) MUST increase. That's a law of physics.
I suggest not making new questions, just edit or add to this one.
