I got an 01 GT thats having some tranny probs.I own the early 01 but the tranny says Tremmec so me and the parts dealer come up with that it has the Tremec 3650 of which I replaced the clutch on in Sep.06.Throwout bearing was bad.Now back around xmas 07 I started hearing some rattling noise just like when the throwout bearing went before,it would stop when i pushed in the clutch,and if i had the windows down I could hear some noise while changing through the first 2 or 3 gears, but it only lasted about a week then stopped making any noise and with in a day or 2 I noticed the tranny having probs changing from 2nd to 3rd while driving and hard to go into 1st or reverse at a stop.But the only times it gives me these probs is if i go over 3k on the rpm's,under that and it all drives fine.It now does it in all gears while goin over 3k rpm's,but if I go over that but hold the clutch in until it idles down under 3k I can usually change without problems.The prob it gives is ether a grind or kinda of a notching in feeling.Im assuming the synchros are bad,but could it be something else,clutch again,clutch fork or whatever?If the synchos are bad i was wondering why I was hearing that noise(kinda rattle to chirping sound) before the current prob arose.Also I think a couple of times early in the morn while it was cold out I think the tranny popped out of first gear as I was pushing in the clutch.

Np Im open to any suggestions at this point,Im saving money for the worst.I can get a completly rebuilt 3650 nearby in Dallas Tx for about $1000 minus the core and If I go and pick it up myself I save the $200 in shipping,so thats what Im prepairing for but would like to knock out the other possibilities first.I was thinking that it might not be the synchros cus all gears really started giving me probs at the same time.Anyone know how to check for a bent clutch fork,never seen one bent before.Is it something I can check without tearing it all down,Im trying to check as much as possible myself,not really any trust worthy shops where im at.Hopefully at worst its the clutch but thats still a lil pricey,around $350 for the whole kit best I remember.
 
thats what I was thinking but on the 01 has a self adjusting.far as I know you cant adjust it or at least I cant find a way.After typing the question I thought about the symptoms more and I went a drove it around and its only about half the time that taking it over 3k that it gives these symptoms.I just find it hard to believe that all synchros would go at the same time,so im looking at it maybe being the cable,fork, or adjuster.Just not sure how to test the cable or adjuster.the only way I know with the fork is to tear it down to the clutch.Also earlier today I remove the cover for where to cable mounts through the fork and I can see the pressure plate and throw-out bearing and it all looks to be moving freely.I might just go ahead and replace the cable if not to expensive for the parts just to get that out of the way.
 
It is self-adjusting but it doesn't adjust itself. What I mean is that you don't really control the adjustment but you control when the adjustment happens. Here is what you do to adjust it:
With the car off, put the parking brake on (so you do go anywhere)
Step on the clutch pedal and put it into 1st
Let off the clutch pedal
Put your foot UNDER the pedal and pull the pedal UP towards YOU
Press the pedal down all the way to the floor

Repeate that a few times and it should adjust you clutch. I always do it more then neccissary just to be safe as doing it too many times can't hurt anything but not doing it enough leaves the clutch out of adjustment.
 
Well i tried the adjusting method,now when i hit more than 3k on the tac I dont get the grinding,it now just seems to feel as if its getting into a bind,does seem to do better thsn before but still has that binding feel,thats in 2nd through 5th.Maybe an over stretched cable.Tommorow im gonna get back under it and check for excessive play in the tranny mount.Earlier when I hit a dip in the road while shifting that seemed to irritate it more,could just be me tho.
 
Both the 3650 and T-45 are Tremecs and say Tremec on them. I'm not sure if it's even possible to install the wrong clutch but it's worth looking into.

Well I knew that,not trying to sound rude.Originally I did get the t45 clutch kit and well they are not even close to the same size.But I will get up under there and make sure,you know how things can get screwed up when listening to someone thats supposed to know what they are telling you.

Well I need to thank you for bringing this to my attention.Here is the original problem in sep 2006,I needed a new clutch so I went to ford and bought a King Cobra clutch kit,brought it home and the cobra and the old clutch where 2 different sizes,so I go back to ford with both clutches,VIN #, and tranny ID tag info,they then told me that I had an earrly 01 but it has had the tranny changed to 3650(I am the 2nd owner).So they gave me the clutch for a 3650 of which is what is in the car now.

Now I just got off the phone with pro motion powertrain and guess what we find out,ITS A T45,Wow way to go FORD.So they can get me a t45 tranny w/carbon fiber synchros,beefed up shift forks,hp rated at 450,for $1200 or the same in a 3650 if I want.Should I stick with the t45?
Also after talking with him I decieded that if I go t45 again im gonna get their King Cobra 2 clutch kit,clutch cable with inner and outer firewall plates,so that the firewall doesnt flex,and a tri Axe shifter that thay will install and setup at no extra charge.
Tranny $1200
Clutch cable,Quardrant,and firewall plates=$119
Tria axe installed=$159
KIng Cobra 2=$219 since I have the wrong clutch...THX ALOT FORD.IDIOTS.

So you all think this is the way to go?Now im wondering if having the wrong clutch is what screwed my tranny up.
 
You can't install the clutch for a T45 or 3650 on the wrong trans. I the reason the clutches are different is that the splines on the input shaft of the trans are not the same. It simply would not fit.

They both have 26 spline if thats what your meaning,The FOrd invoice I have is for the 3650 clutch.The Tag on the tranny says its a t45,PMP says the only difference is the diameter of the clutch,3650 is 11",and a t45 is a 10.5" disk,Im not trying to argue just saying that this is whats going on.

I remember hearing that the best way to tell what trans you have is by looking at the drain plug location. I'm not sure what to look for exactly but if you do a quick search on this forum I'm sure you will find it.
10 people can tell you 10 different things, so don't make any decisions until you know for sure. If it is possible to have the wrong clutch (maybe correct disk and incorrect pressure plate) maybe there's nothing wrong with your trans at all.
Good luck bro.

Ok this is how I have verified it.1st i went to tremec site and looked up the info on the ID tag on the tranny,it says that its a t45,thenPMP says the other way to tell is by the drain plug.If the drain plug faces down to the ground its a 3650,if it faces straight out to the passenger side its a t45...mine goes straight out to the passenger side,so the drain plug and ID tag says its a t45.I can get a rebiuld locally with upgraded bearings,synchros,and forks for 450-500,if i do a complete rebiuld at most it will be 875.00.for the t45 that is.Thx for the info,you are correct on the drain plug.
 
If anyone here would like to double check me heres the info on the tranny ID tag on the housing extension bolt:

YP33 7003AA K1501
TSET 1386AC 11516
The way im reading this is that,TSET=T45,AA-Manufacturer Date=January 2000,K1501=10/15/2000 shift 1
Drain Plug faces passenger side.This info was gotten from Tremec's web site under literature.

A few years ago when I had a Fox body, I found a guy on Stangnet who rebuilt my T-5 for $100 and did it in a week. You can find a rebuild kit for a T-45 for $175 here: http://www.promotionpowertrain.com/1231590.html
If you can find someone who can do it for you it might save you a bundle.

I was under the impression that they had a different spline count. I must be wrong about that. But the only way you could bolt the bigger clutch on is if the flywheel was drilled for both sizes.

Thats exactly what I had thought but Pro Motion Powertrain said that it could bolt up,but that i dunno about.All I know is what the tag says and where the drain plug is located at.So whith that being said I think Ill go with that info as to it doesnt make sense to go against what it says.Im sorry if I sound as if im arguing the matter, im not, just giving all the info I have come across as I want to get this right.
