Need Help Changing Clutch 1988 F150 Sign In

My clutch is slipping in my 88 f150. I have the clutch kit (clutch, pressure plate, throwout bearing, pilot bearing and pilot tool). I started removing the transmission today, but I can't figure out how to disconnect the hydraulic line that connects to the slave cylinder from the side of the transmission. Anyone know how to do this? Or, is there a way to remove the transmission without disconnecting the hydraulic line? I have changed F100/F150 clutches in the past, but all had mechanical linkages. Any help with this would be appreciated.

Pics didn't expand for a good look at this. It matters whether 4 or 5 speed - which?

Is the flex hose going right to the slave or just line? If you can't see how to disconnect it there it may be either done up to next connection OR it stays there while trans is removed then you could get at it. Listed clips that hold one style.

Hydraulic line stuff shouldn't deviate from common brake line tools used. Flare nut wrenches, crow footed flare nut wrenches/sockets if you will.

Look for info on replacing the slave cylinder as if that's all you were doing.

What engine, trans (# of speeds) and is this 4X4 or not??

1988 2WD 4.9L 5 speed. The master cylinder for the clutch is on the firewall, and the line runs down and into the side of the transmission. I'm guessing the slave cylinder is inside the bell housing? The '90 master cylinder is mounted on the transmission, so on that one, you just pull the tranny and it all comes with. This one, the tranny will only move back 3 or 4 inches before the slack in the line is used up. Also, this doesn't look like a conventional steel hydraulic line. It looks like hard plastic and is a little flexible. I would prefer not to disconnect in such a way that I get fluid everywhere or have to bleed the system. Seems like the designing engineer would have made it so that the clutch plate could be R&R without having to take apart this other system. Maybe that's why the '90 is different. I'm attaching a picture. The silver "nut" you see at the point the line goes into the bell housing is not a nut. It's just a collar and turns pretty freely. I was hoping there was some trick to getting this to come off, like a pnuematic quick-connect fitting or something.

You’re 100% right, it is a quick connect or that’s what it was designed to be. LOL
Take the line and gently push it into the slave cylinder.
There should be a white or black plastic collar that looks kind of like a bushing that should move fairly easily around the hub (for the lack of a better word) of the line. Slide this collar into the slave cylinder; you may need a screwdriver or something that you can use to push it in with. This collar, when pushed in all the way (evenly); should release the clips holding the line in the slave cylinder.
Once the collar is pushed in, the line should just pull out of the slave cylinder connector; that’s if you’re holding your tongue just right. LOL
Sometimes there is a bit of dinking around with the couplers to get them to come apart.

Have a look at the new slave/release bearing assembly; you should be able to see these clips that I’m talking about.

There is a check valve in both the slave cylinder and in the end of the line, to stop the fluid from running out.

If by chance you were only planning on replacing the release bearing and not the slave; I would maybe rethink that. The slaves were well known for leakage issues; especially if you’re putting it in behind a new clutch.

It would be a shame to have to pull the trany again.

I'm struggling to find just what this sucker is all about. Below is about all I could find and there is a special tool for this IF and ONLY IF this info is close to what you have in front of you. Your pic was ok but I couldn't make any suggestions from just that.

I found the slave cylinder for the 5 spd and it's different as you've found and the diagrams that would have been nice were shut off for now????? Best I could grab out of the script was the trans does need to come out to replace it - not much help so far.

If the stuff below shows I still don't see how the tool would really help?? More questions than answers for you - hope someone's watching who has done this one - I haven't.

Guessing: Line needs to be removed and fluid will be lost meaning bleeding it out will be required. I can feel your frustration and don't have a quick answer - sorry,

Clutch removal tools are available to rent free at AutoZone and places like that. It's a kit with assorted stuff to remove clutches that require the kit at all - some don't!
