2003 Cobra Will Not Go Into Any Gear.

Sounds like the quadrant has stripped. Do you have an aftermarket clutch quadrant ? If not I suggest you get one. The factory quadrants are usually plastic and are prone to strip. When they strip they take the adjustment out of the cable causing the clutch to stay engaged....that then keeps the car from easily being shifted when running. Seems like you have no shortage of funds....I'd suggest a new Ford cable , an aftermarket aluminum two hook quadrant, and a firewall cable adjuster.

If you still have the old t56 I'll buy it....broke or not. [emoji106]

The only other thing I could think of is the clutch fork pivot.

How does the pedal feel ? Should be able to feel the clutch release through the pedal...about 1 inch off the floor. The hook closest to the pedal should be good.

One of my cars had an issue with the firewall flexing not allowing the clutch to disengage properly. It was actually flexing right where the grommet goes through the firewall. The edge of the plate should be flat and squared. I used 1/4 inch steel plate....I think 3 x 3 inch....drilled a hole for the adjuster and never had a problem again.

What brand cable are you using ? I've been through a situation where the cable housing was actually being pressed through the black plastic end at the firewall. That's when I started using only Ford or MM cables....all the rest are junk.

I'm looking for a t56 for my turbo fox. If you ever want to sell I'll give you decent money. I know what they're worth. Don't want to spend 3 grand if I don't have to. Lol

Its got to be something simple....it always is. Smh
