LIBERTYS FACE PLATE AND PRO SHIFT GEAR MODIFICATIONS

never worked with them but faceplating is an option to remove the synchro's for a semi race (still use clutch) option.

That's not bad at all!

Crap! After 36k miles, my tranny started grinding when I downshift from 6th to 5th. Made an appointment this Saturday. This sucks donkey nuts!

Bad Synchros slowing down the shift won't matter.. Do you do a lot of coasting?

It's seems like it's mostly happening when I skip to 6th from 4th... and downshift to 5th. @ the dealership now. I hope I don't screwed totally over.

...well of course the tech can't replicate it. FML.

Yep I feel your pain brother as I'm at 32,000 but past the 3 years and mine has trouble going into 5th and grinded a few times in 2nd already. Of course it didn't matter if it was in warranty cuz the TT would get the blame for the tranny anyway. Im really hoping its the JWT clutch and the new osgiken with hd slave cylinder is the fix. I didn't have that issue until I put in the new clutch. Here's to hoping or FML for me too:inoutroflpuke:

Once it starts grinding, it will progressively worsen and become more apparent.

Funny thing is, it grinded three times on my way to the dealership (about 5 miles away), but not when the tech was test driving the car. I guess I'll have to wait for it to get worst. At least it's on the record.

Ive noticed that it only grinds when the tranny is cold. it happens only when my car has been off for a few hours. Once it warms up (about 5mins) it works as normal.... is that your experience?

Maybe it would be a good idea to take it to the dealership, leave it for a few hours and try again??

I found this post while searching for someone with my issue: I don't have a "grinding" problem, but it seems that there's a hesitation when shifting from 1st to 2nd. It's almost like the shifter catches on something slightly in the middle of 1st to 2nd, then goes into second. When i shift from 1st to 2nd slowly (for instance, in a parking lot) I also hear a "clunk" when it gets into second gear. Is this normal? I've only got 7k miles on my '11 base model. Thanks!

Clunk is normal when you undershift. The notchy gearbox is also normal. Unfortunately for a few of us, bad syncros are normal too. My tranny was replaced at 18k(third gear) on '09. I've read on here they beefed up the syncros since then.

The Z has been sitting in the driveway since the last visit to the dealership. I need to slap new tires on her and will be doing that tomorrow. I do notice that it does happen more often when it's still cold. I really hate leaving the car at the dealership though, so I might try and see if I can capture it on video somehow.

My 5th grinds about once a week and always before the car has yet to fully warm up (oil temps etc).

Been like that for about 6 months but hasn't gotten any worse so I haven't gone to the dealer yet since it's unlikely that it will replicate on a tech ride.

I'm hoping that when it does get worse it won't go from mild to catastrophic all at once.
