Helped the shifting no matter what the outside temp was.

But maybe your clutch hydraulics have air in them. Try bleeding it. Get under the car, unbolt the slave cylinder (2x 13mm nuts), slowly allow the piston to extend, then compress all the way. Hold for 15 seconds, then slowly let piston extend again, and push it back in. Hold. This will push any air out of the slave and back into the reservoir. Reinstall the clutch slave. Pressure bleed the brakes and clutch with fresh ATE Super Blue or Type 200 (gold) brake fluid. Provides better wet and dry boiling points than any DOT 3 or 4 fluid. No one likes silicone based DOT 5 fluid, so I'd stay away from it.

Remove the lower dash panel on the driver side. Check the pedal bracket to make sure it's not cracked. If it's cracked, you can try to get it welded, but you'd be better off replacing it with a new one. They usually only fail if you've installed a heavy-duty pressure plate.

Good Luck!
