grinding into 3rd when shifting 01 cobra

hey im just wondering if anyone else has this problem...if i drive normally and shift into 3rd slow it wont frind but if i try to make anything of a good shift it grinds is my tranny blown?synchros? please tell me be greatly appreciated

I had that same problem with 3rd gear on my old cobra. It was bad syncros.

The T-3650 tranny in the Cobra's, GT's, and Mach-1's are known for bad synchros and bent shift forks. Check out the 4.6 section on this board and look at the sticky at the top. It is bad enough, that the members are trying to force Ford into making a recall to fix the tranny's

I thought the 99 to 2001 cobra's has t-45 trannys?

But, yes sounds like a bad syncro... I had the same problem in my old 86 GT I had... I could make a normal shift into 3rd.. but, if I quick shift it, it would grind... a replaced syncro fixed my problem.

Wow... that was food for thought - thanks Cobra90GT!

I have the same prob with my 01. I do alot of 1,3,5 shifting for better gas mileage and its even worse when I do that. Started after a hard grind into 3rd at the track a couple of weeks ago. :damnit:

thanks thats what i thought it was im glad its not the tranny blown...how much does it cost to replace the synchros?

I have some of that when I go to 2nd gear but during normal shifing more then anything...seems like when it does it and I get pissed and slam it into 2nd the next time around it does not do it?

Just the trannys, the pro 5.0 helped with some of it and I also noticed if I pause and go slow after I fell a "bump" I can easily pull it into 2nd. Its become nearly a habit now.

My 99 Cobra was like that and I also had trouble getting into reverse. I put in a can of limited slip differential modifier about a month ago. No reverse problems & much smoother shifts 1-2 & 2-3!

A can of rear end fluid? into your tranny?

I have the same thing going into 3rd, sometimes mine even pops outta 3rd...i went for the 3rd gear burnout and failed myseribly..i also had a new tranny put in by ford 3 yrs back for a recall about them getting stuck in rev...all of a sudden,after 2yrs with the new "none stick in rev." tranny it gets stuck every once in a while now..whats the deallyo???
