You will have to pull the transmission to change it because the slave cylinder is on the inside of the bell housing. It's a lot of work to change such a simple and failure-prone part, so it would probably be best for you to change your clutch out with it. If you're unsure of how to do it, pick up a Haynes manual for your truck from your local autozone, advance auto, oriely's, etc. and look over the process. They book is probably about 15 dollars and will be invaluable to you during the time you own your ranger.
