Hey, i have a 2008 4.0 with the manual T-5 tranny. I was wondering if anybody has had trouble with the gears grinding. It started with 4th gear and it would only grind a little when the transmission was cold. Also it would only do it if i shifted into 4th quickly. Then about 2 months later, 5th gear started grinding, but only when i would pull hard out of the gear before it. Then just about 2 weeks ago 3rd gear started grinding a little bit when i would come fast and hard out of 2nd.

Any ideas??
Should i just let it break in a little more? i only have 6600 miles on it.

so i took it to the dealer, and they wouldn't even tell me what was wrong with it, they just said they had to order me a new transmission

the dealership replaced it and tried to blame it on me... i got a whole new t5, but they said they won't do it again. i have a friend with an 06 mustang with a t5 that had the same problem. ever heard of it happening? they said the synchronizers went out and that caused gear damage.

synchronizers on the mustangs must go out all the time. My 5thgear and reverse on is ****s up some times and my dad has a 2001 same ****

i talked to a guy that used to work in the ford factory in the mechanical department. he said that downshifting while you're going too fast for the next gear down or whatever gear you try to put it into is most likely what did it. i haven't done any major amount of downshifting with this new transmission and it's working perftectly. so- i'm guessing problem solved.

I've had mine in the shop twice for this same problem. First time they told me nothing was wrong and about a month later they rebuilt the transmission. They told me its actually common amongst v6 manuals, the transmissions are usually the thing to go out first especially with the way some of us drive them.

Do you think that heel toe shifting would help offset this problem?
