Hi Rob, We met in PHX a few years ago with Ivan-6Speed. My 07 vert was mfg in Feb 07. When the car had barely 2000 miles on it I started getting a grind when getting on it while going into second gear. The TSB I had done was a tranny rebuild for new syncros, the hardened input shaft, a new steel flywheel and a dual disc ceramic clutch. My Master Mech at the time said second gear was serviceable but he could see that it had been grinding so he put in a new second gear anyway since the car was so new. (I probably ground second about ten times or so.) I haven't driven the car much and only have about 7000 miles on it now. But I have ground second about a dozen times or so now and it doesn't seem to happen only while really pushing the car real hard and wheel spinning anymore. How do I know if my tranny needs to be opened up for new syncros and if second gear should be changed again? Thanks, Mark
Hi Mark, I enjoyed having lunch with you and Ivan on that Hot PHX day a few years ago.
Now as far as your 2nd gear problem. Ford has a procedure listed to evaluate weather or not the transmission needs any syncro work done to it when they replace the clutch. I will post the proceedure and you could probably do it yourself. Just make sure you do it in a open clear space, not in your garage. Would hate to have you launch into your house. The procedure is part of the TSB.
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 lb-ft (22-45 N•m) 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
Mark if your car passes this test, then the clutch assemblies replacement is all you need done to your car. If it does not pass the test, then you will need some transmission service work along with the clutch work.
Hope this helps and let me know if you have any other questions,
Rob
