Replacing slave cylinder

I'm in need of replacing my slave cylinder because of a leak in the line somewhere and I'm new to this so I'm wondering if I'm gonna have to drop the transmission to get to it and replace it or not. I know that until around 95 they were located inside the tranny housing I believe but I don't need what's all involved with actually replacing it or if there's any tricks t doing so because I really don't feel like dropping the tranny but if I have to then il do it so if anyone knows wether I have to drop it or not that would be helpful..also my jeep is lifted 5.25 which would make dropping it easier probably....any clarification would be appreciated

well you need to educate yourself here's how....
crawl under the drivers door and look at the transmission and if you see this then you have an EXTERNAL SLAVE CYLINDER.....

If you dont see this then you have an INTERNAL SLAVE, if you know you have an issue with it then you will have to remove the transmission. it will some what like this....

Before you do anything you need to know where it is leaking, if it the line then you can change it with out removing the tranny.

Well the line going from the master to the slave is separated into two lines and I've already replaced the one connecting t the master so now I'm under the impression it has to be either the slave or the line connecting to the slave that is leaking because there is definitely a leak becaus ei have t fill the reservoir with fluid everynight or I won't be able t shift the next morning.

I know mines internal but i have no idea how I would know if it's the slave or just another line if possible I would love to keep the tranny bolted to the jeep lol but me and my pops have pretty much narrowed it down t the slave unles me and him are missing something which we are far from being experts so it may not be th slave.. And thanks for the pictures is always easier to look at them then looking while under the jeep

ok well under the dash is where the master pokes through the fire wall, look and see if you have any wetness dripping down and some have a rubber dust boot move it around and see if you get any fluid. as far as the slave, if its leaking you will have black wetness at the bottom of the bellhousing due to the leak and brake dust from inside.

If the master is leaking under the dash would that explain a constant slippery fluid (brake fluid) on the floor mat that is always making me slip even when there's no water anywhere near my jeep lol you may have just hit two birds with one stone

Umm yeah just checked and I can see drops coming from the master thanks a lot for connecting the dots for me lol I probably would have never been able t do that lol and this whole time I could even see a trail of fluid coming down the firewall from behind the dash and again just thought some gasket somewhere was letting the elements in lol well I feel dumb but problem solved thanks buddy
