Trouble Shifting And Getting Into Gear

[tunerEATER]

I have an 87 GT with a B and M pro ripper shifter, the clutch is extremely heavy but it has been since we got the car. when I first start driving the car goes into all gears relatively easy, i mean its a lot tougher than my vw passat but i can get it into gear fine. I noticed that when im driving for an extended amount of time 30 min+ the car doesnt want to go into gear, i can force it into first at a stop light but when i accelerate and try and go into second it wont go for a good second and a half, I read that it may be the clutch cable and I adjusted it by pulling up on the clutch pedal and pushing it to the floor. This method seems to work for maybe 2 or 3 minutes of smooth shifting, i have to do it constantly at stop lights to be able to shift normally. i believe the car has a new clutch but other than that i believe the transmission is stock, any long term solution out there?

thanks

Do you still have the factory cable quadrant?
If you have to keep adjusting it, from what I understand the plastic adjustment teeth can strip or slip with age.
Just a thought.
I am still learning the Ford cable system, but I know clutches, and when gears are hard in and out, it is usually the clutch not fully disengaging, which comes down to adjustment for the most part.

What ratio411 said, it sounds like your quadrant isn't holding. If it is the factory quadrant, and it had a heavier clutch put in, it could strip the teeth off of it a lot quicker.

so what should i buy/replace to fix the problem? the plastic tooth piece?

Purchase an aftermarket quadrant. But I would check the original to make sure that is your problem first. It could also be your cable stretching, or a number of other things. Just sounds like your quadrant b/c of when you readjust it by pulling up the clutch petal, it gets better for a little bit.

Clutch adjustment
Do the clutch adjustment first before considering any other problems. With the stock plastic quadrant and cable, pull up on the clutch pedal until it comes upward toward you. It will make a ratcheting sound as the self adjuster works. To release to tension of the stock quadrant, use a screwdriver to lift the ratchet paw up and out of engagement with the quadrant teeth.

A binding clutch cable will make the clutch very stiff. If the cable is misrouted or has gotten too close to the exhaust, it will definitely bind. The binding common to adjustable cables is often due to misplacement of the adjusting nuts on the fork end of the cable. This will also cause the cable to wear and fray. Both nuts should be on the back side of the fork so that the domed nut faces the fork and the other nut serves as jam or locknut to the domed nut.

Clutch pedal adjustment with aftermarket quadrant and cable: I like to have the clutch completely disengaged and still have about 1.5” travel left before the pedal hits the floor. This means that I have only about 1” of free play at the top before the pedal starts to disengage the clutch. Keep in mind that these figures are all approximate. When properly adjusted, there will not be any slack in the clutch cable. You will have 4-15 lbs preload on the clutch cable.

The quadrant needs to be replaced if you use any type of aftermarket cable or adjuster. My preference is a Ford Racing quadrant, adjustable cable and Steeda firewall adjuster. The adjustable Ford Racing cable is just as good as the stock OEM cable. It allows a greater range of adjustment than a stock cable with a aftermarket quadrant and firewall adjuster. Combined with the Steeda adjuster, it lets you set the initial cable preload and then fine tune the clutch engagement point to your liking without getting under the car.

Using a stock OEM cable, firewall adjuster and a single hook quadrant may result in not having any free pedal travel before the clutch starts to disengage. I found this out the hard way.

Also make sure your firewall is intact where the cable comes through it. There's a ridiculous amount of flex there with stiffer clutches.
