Bad Synchros 08 GT?

Post by rgoddard on Wed Nov 23, 2011 9:50 pm

Ok so my 08 GT 5speed I bought certified used from the dealer with 13,000 miles on it now its got about 28000. The car was stock as far as I could tell when I popped the hood but it had somethings I new were not. A gt500 spoiler and a cdc chin plus a hurst short throw. I got the warranty.

I know hurst shifters can be choppy but when the clutch is in it goes into the gear positions pretty smoothly. Now when I first got it every once in awhile getting into 3rd would make a very small noise and a little resistance. Now I am noticing this is starting to pick up in frequency.

I also last summer tried to hunt down a noise I found at the beach that echoed off the cars around me with the windows down when letting out the clutch. kinda like a tapping sound. Ford never found it but I still believe that they probably didn't want to do anything about it.

When I first got it I was cleaning the engine bay and noticed some small paint scratches like someone most likely had a cold air intake on it before and possible other mods then put it back to stock to sell it.

This kinda makes me think it could have been ragged on a little bit.

Problem is I don't know what the warranty covers or even what to look for if its the synchros.

Please let me know what you think! Thanks for all of the previous info before! Im pretty sure a whipple is coming in June!

If it grinds when going into gear its syncros. If it is hard to pop into gear when engine is off, and clutch disengaged, its shifting forks (which is very uncommon on the 3650), or the remote shifter needs adjustment. If its the adjustment you will notice one top gear and one bottom gear have the same issues. If that's the case either things need to be moved and tightened down or get a box of washers for shims and play with it.

Also I believe the Hurst has throw stops to keep from bending forks. Are they adjusted?

Take the knob off - unscrews. Then the skirt - 4 pop clips, look at bottom if shift shaft. There will be two bolts with locknuts. To adjust, screw bolts all the way in. Then put shifter in third. Hold forward slightly. Adjust bolt out until it touches shaft. Then lock with nut. Do the same in 2nd or 4th.

Where is Bronson. I said shaft and nuts a couple times...

So when you say put it in 3rd and hold forward slightly. Is it supposed to be all the way in 3rd and push it just a little further forward?

Correct. The stops are just there to jeep you from bending the internal forks. But even then you have to be a gorilla to bend those forks... I have bent them in t5's but our trannys have ticker forks.

Dammit Bronson... I said tranny

Are the bolts you are talking about the bolts that go through the shifter shaft or are they on the actual base of the shifter? Sorry I was looking at the pics on the shifter online. I just want to make sure im doing the right things since I have never messed around with this part before on any car.

Housing is circular. Only two stops so furthest pattern should be set. These are remote shifters so there is play. Just make sure all go in gear and lock

If you need a stock shifter, I've got one in the garage minus the shifter knob.

I don't recall the Hurst short throw having an adjustment. I have one, the only issue I've had was that the assembly would buzz. Hurst sent me a dynamat kit and have not heard it since.

Early Hurst models didn't have them. Early 06 models. Since then they are the copy if the pro 50 shifters. As you can see they have the throw stops

Ok sorry its been all day but I did make the adjustments but it doesn't look like it will change it all that much. Tomorrow Im going to take it out for a drive and run it in to 3rd and different speeds to see if anything has changed. Thanks for the help so far! I will post back as soon as I know.

Today I drove it around and it feels the same. Actually after before I even made the adjustments the shifter didn't hit the stops at all. It still doesn't so I know its not that. Now to find out what my next step will be.
