I am wondering if there is a way to make the clutch easier to use, like bleed it with a better fluid or a better line or lube the crap out of something.

Any suggestions?

A twin disc clutch will have a much lighter pedal and smoother engagement.

I've got the '10 clutch assembly installed on my '07. The chatter is gone and the amount of pressure required on the clutch pedal has been greatly reduced. A true pleasure to drive. If you anticipate high power go for the McCleod.

Cheers,
Ray

The mcleod rxt I put on has the exact same pedal feel as my stock clutch did. It's for sale cheap in the market section cheap if your interested in a lighter pedal.

I put a 2010 clutch in my '07 as well and it is amazing how much better it drives.
I didn't realize how much I was compensating for the old clutch.

+1 on the 2010+ clutch. Waay easier to drive. If you have a friendly service advisor at your Ford dealer, he may be able to get you some help. You are probably still covered under Powertrain Warranty.

Here is the TSB:


10-3-8 SHELBY GT500 - CLUTCH DRAG

Publication Date: February 12, 2010

FORD: 2007-2009 Mustang


This article supersedes TSB 09-19-11 to remove the production fix date, update the Service Procedure and Part List.

ISSUE:
Some 2007-2009 Mustang Shelby GT500 vehicles may exhibit the following clutch/transmission symptoms: hard to disengage or engage 1st and reverse, hard to shift all gears, vehicle creeps with transmission in gear and clutch pedal fully depressed without brake pedal application. These symptoms may be caused by the clutch not disengaging fully when the clutch pedal is fully depressed. This may be due to flywheel distortion caused by excessive heat build-up during unique traffic conditions (example: severe stop/go urban driving, excessive clutch slipping). The clutch system is designed for performance driving conditions.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Located at the end of the procedure are Figures 1, 2 and 3 which show the typical appearance of a flywheel and clutch that has been damaged due to overheating of the clutch. Figures 4, 5 and 6 show the typical appearance of a good flywheel and clutch.

This procedure does not apply to or correct the normal characteristics of the twin-disc cera-metallic clutch used in the Shelby GT500 vehicle or normal wear. The twin disc cera-metallic clutch incorporates racing technology to combine a low inertia assembly with a very durable friction material with high torque capability. Depending on your driving technique, the smoothness of how the clutch reacts to clutch engagements may be different from other vehicles that use a single disc clutch system. Also refer to pages 8 and 9 of the GT500 Owner Guide Supplement for additional information.

Normal Operating Characteristics Of The Twin Disc Cera-metallic Clutch

Clutch chatter/shudder when engaging the clutch.
Narrow or abrupt engagement point.
Hiss upon clutch engagement or disengagement.
Transmission gear rollover noise at idle.
Gear rattle noise at very low speeds when in 1st or 2nd gear.
Normal wear.
Diagnosis And Service Procedure Update

Based on engineering analysis of all of the returned transmission components replaced when performing the prior TSBs, it has been determined that the synchronizer assemblies and transmission input shafts do not exhibit any abnormal wear that would require transmission component replacements.

A diagnostic procedure has been developed to confirm that the transmission synchronizers are operating properly and prevent any unnecessary transmission repairs.

Transmission Synchronizer Diagnosis Procedure

The following procedure is to be used to determine if the synchronizer assemblies in the transmission may have been damaged by attempting to operate the vehicle with a dragging clutch.

Set parking brake.
Transmission in neutral.
Start engine and allow it to idle.
Clutch engaged - pedal fully released.
Attempt to shift transmission into first gear by firmly pushing shift lever approximately 5-10 lb-ft (22-45 N-m) force for 2-3 seconds.
If the synchronizers are okay, the transmission will not make any clash or grinding noise. You will not be able to move the gearshift lever into the selected gear (the synchronizer will block out gear engagement) and the engine RPM will decrease slightly.
Repeat the synchronizer test (Step 5 and 6) on all of the other forward gears.
If the transmission passes the synchronizer test, the transmission will not require additional service; proceed with clutch/flywheel replacement only. Refer to Clutch Replacement procedure.
If clash/grinding noise is found when performing the synchronizer diagnostic, the transmission will need to be repaired along with the replacement of the clutch. Refer to Transmission Repair procedure.

Clutch Replacement

Remove the transmission per 2010 Workshop Manual (WSM), Section 308-03C.
Remove and replace flywheel per 2010 WSM, Section 303-01C. Discard old bolts and use new bolts.
Install new pilot bearing per 2010 WSM, Section 308-01.
Install new clutch disc and plate assembly per 2010 WSM, Section 308-01. Using new bolts.
Apply a small amount of Motorcraft® PTFE Lubricant to the clutch hub splines per 2010 WSM, Section 308-01.
Install new clutch slave cylinder and hydraulic line per 2010 WSM, Section 308-02.
Install the transmission per 2010 WSM, Section 308-03C.
Refer to Powertrain Control Module (PCM) Reprogramming.
Transmission Repair

Remove, drain, disassemble and clean the transmission per 2010 WSM, Section 308-03C.
Remove and replace input shaft and all synchronizer assemblies per 2010 WSM, Section 308-03C.
Assemble the transmission per 2010 WSM, Section 308-03C.
Install the transmission per 2010 WSM, Section 308-03C.
Refer to PCM Reprogramming.
PCM Reprogramming

The PCM must be reprogrammed after the clutch is replaced. Reprogram the PCM to the latest calibration using IDS release 65.07 and higher. This new calibration is not included in the VCM 2010.1 DVD. Calibration files may also be obtained at Buy Motorcraft Parts Online | Official Motorcraft Auto Parts Site | FordParts.com.
