Grabber Posted September 20, 2009 Report Share Posted September 20, 2009 TSB 09-19-11 SHELBY GT500 - CLUTCH DRAG - BUILT BEFORE 9/1/2008 This article supersedes TSB 9-9-2 to update the Service Procedure and Part List ISSUE: Some 2007-2009 Mustang Shelby GT500 vehicles built before 9/1/2008 may exhibit the following clutch/transmission symptoms: hard to disengage or engage 1st and reverse, hard to shift any gear, 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. 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. 1. Set parking brake. 2. Transmission in neutral. 3. Start engine and allow it to idle. 4. Clutch engaged - pedal fully released. 5. Attempt to shift transmission into first gear by firmly pushing shift lever approximately 5-10 lbf (22-45 N) force for 2-3 seconds. 6. 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. 7. Repeat the synchronizer test (Step 5 and 6) on all of the other forward gears. a. 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. b. 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 1. Remove the transmission per Workshop Manual (WSM), Section 308-03C. 2. Remove and replace flywheel per WSM, Section 303-01C. Discard old bolts and use bolts provided in flywheel kit. 3. Install new pilot bearing per WSM, Section 308-01. 4. Install new clutch disc and plate assembly per WSM, Section 308-01 (vehicles with solid design flywheel). Discard old bolts and use bolts provided in clutch kit. Tighten bolts to 89 lb-in (10 N-m) in a star pattern. Tighten an additional 90 degrees in a star pattern. 5. Apply a small amount of Motorcraft® PTFE Lubricant to the clutch hub splines per WSM, Section 308-01. 6. Install the transmission per WSM, Section 308-03C. Transmission Repair 1. Remove, drain, disassemble and clean the transmission per WSM, Section 308-03C. 2. Remove and replace input shaft and all synchronizer assemblies per WSM, Section 308-03C. 3. Assemble the transmission per WSM, Section 308-03C. 4. Install the transmission per WSM, Section 308-03C PART NUMBER PART NAME 7R3Z-6375-B Flywheel Kit (Includes Bolts) 7R3Z-7L596-A Clutch Kit (Includes Bolts) 7R3Z-7C391-B Transmission Kit XG-8 Motorcraft® PTFE Lubricant XT-5-QM Motorcraft® MERCON® V Automatic Transmission Fluid PM-1-C Motorcraft® High Performance DOT 3 Motor Vehicle Brake Fluid XG-1-C Motorcraft® Premium Long-Life Grease TA-30 Motorcraft® Silicone Gasket and Sealant TA-25 Motorcraft® Threadlock and Sealer F6ZZ-7600-A Pilot Bearing 1R3Z-7052-AA Transmission Input Shaft Oil Seal WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage IMPORTANT: Warranty coverage limits/policies are not altered by a TSB.

Grabber Posted September 20, 2009 Author Report Share Posted September 20, 2009 (edited) You may be asking - What are the differences? Well, they are telling the dealer how to test the syncros to see if they are bad. If they are not bad...then they leave the tranny alone and just do the flywheel and the clutch and pilot bearing. 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. 1. Set parking brake. 2. Transmission in neutral. 3. Start engine and allow it to idle. 4. Clutch engaged - pedal fully released. 5.

chuckstang Posted September 21, 2009 Report Share Posted September 21, 2009 clutch engaged, fully released What does that mean? I want to perform this test myself Quote Link to comment Share on other sites More sharing options...
Grabber Posted September 21, 2009 Author Report Share Posted September 21, 2009 clutch engaged, fully released What does that mean? I want to perform this test myself Start the car. Leave your foot off the clutch pedal. (it's engaged) Then do the test by trying to put pressure on the syncros. Follow the directions in the TSB when doing this. (Don't push too hard and launch the car into your garage by putting it in gear) Quote Link to comment Share on other sites More sharing options...
chuckstang Posted September 21, 2009 Report Share Posted September 21, 2009 maybe I will pass, after looking at the test again, too much gray area It says push firmly and then in the same sentence 5-10ftpounds of force IMO firmly and only 5-10 should not go in the same sentence, makes no sense to me. Honestly Id like to launch it off a cliff so I could collect on it in full LOL Quote Link to comment Share on other sites More sharing options...

shelbypowered Posted September 21, 2009 Report Share Posted September 21, 2009 I have no idea how long these tests for a bad clutch- flywheel - syncros will go on but it is getting close to the point where ford must be wondering why someone in engineering picked this system. Grabber works hard to keep us up to date on all the clutch issues and I thank him for that- who I do not thank is the engineer who designed this lousy system- most ruining of syncros are the result of the poor clutch- in the meantime keep up to date on the aftermarket clutch systems and if you can sock a few bucks- I guess quite a few- aside and pick another clutch for your car- Ford has been generous but are they admitting a mistake or standing behind a poor design or both. I know that this is negative thinking but the future for the early gt 500s under the headline clutch will be what aftermarket clutch do I use. When a stock clutch goes out you have to ask yourself was it me or the desgin- ford - Iwould guess- wondered where the problems would arirse when they put five hundred ponies behind our cars- it could be worse as the rest of the drivetrain seems to take the hard hits. That left peddle always leaves me in a worry- My ford tech. and I know each other by first and last name and that may or may not be so good. Thank all of you for posting your results on aftermarket clutches for our car as you are the true pioneirs for our clutchl issues and it is out of pocket expense for you all. I believe going to ford for a free tsb or related issue is just buying time not curing the problem. I wish grabber had more time to look into aftermarket clutches but that might solve the problem and start poor grabber on trying to defend one ovet the other- his staying in a neutral corner and providing valueable information is the best spot he could pick. thanks grabber- Quote Link to comment Share on other sites More sharing options...
Spring Lil Cobra Posted September 21, 2009 Report Share Posted September 21, 2009 yea, thanks Rob. I'll test this on mine (even though I had the TSB done) and see how it performs. Quote Link to comment Share on other sites More sharing options...
SVTpower Posted September 21, 2009 Report Share Posted September 21, 2009 Anybody remember before this car was released how Ford tested the durability of the powertrain with no less than 500 launches??? Yeah right..........maybe with a special one-off clutch that never saw production Quote Link to comment Share on other sites More sharing options...
chuckstang Posted September 22, 2009 Report Share Posted September 22, 2009 I am curious to know how long my original set up would have lasted. I find it very odd that my car is much worse now after the TSB Really makes me think its still not the clutch, but the dam retarded Ford techs I appologize and dont mean to insult but how is it that many out there with the TSB done have no issues and then many people like me with many Quote Link to comment Share on other sites More sharing options...

SicShelby Posted September 22, 2009 Report Share Posted September 22, 2009 I think the pilot bearing has been added as a replacement as well, is that right Rob? I don't remember that being a part of the TSB when they replaced mine... Glad they put that in there. Quote Link to comment Share on other sites More sharing options...

19Maddog64 Posted September 27, 2009 Report Share Posted September 27, 2009 After the section on removing the clutch the next step should be "PLACE IN DUMPSTER"! Sorry had to say it - I went aftermarket. Quote Link to comment Share on other sites More sharing options...

cutter Posted October 1, 2009 Report Share Posted October 1, 2009 Are they doing the tranny syncro and input shaft replacement on yours too? Cutter, I hope they get it right this time. Do you still have both your 500's ? Yes...I picked up the vert today and its perfect, pedal is easy to push and don't have to slip the clutch anymore to engage, dropped off the 08 and they are balking about replacing it, I guess ford is not wanting to replace the clutch, flywheel but stay out of the tranny is possible...will know more in a few days, care only has 2200 miles on it...but the vert only has 5200...I seen the bill, ford only pays alittle over 600.00 for all the labor.....parts cost around 5K...

So that means it has the revised inputshaft already. The 26 male splines are a tad wider and smoother too. If the syncros test out good, then you don't need them to break into your tranny. Just have the flywheel, clutch and pilot bearing replaced. I hope all goes well. Let us know how you make out. Quote Link to comment Share on other sites More sharing options...
