Car is a 65 fairlane converted to t5. Before the conversion I didn't have the whining noise so I believe its either the trans or TOB. I'm thinking I might of adjusted the clutch fork to where the TOB is siting on the fingers on the pressure plate (know that's wrong) I'm hoping that's it, but never that lucky. Any help would be appreciated.

My buddy had the same problem with his t5. When we replaced it with the Astro performance t5, we found that the "bearing retainer", the shaft that the throw out bearing rides on, had sheared off near the trans. It was spinning with the input shaft. We would tease him about it sounding like a supercharger.

I think its supposed to ride on the fingers which goes against my thinking, too. However, my T5 conversion in my '66 has the TOB riding on the fingers for the last 9k miles without a problem. Every Fox Mustang 5 speed is like this, too.

What's the origin of the T5? Poorly rebuilt maybe?

That's almost exactly the noise, but wouldn't it make it through all the gears, including reverse? But the t5 is from a scrap yard, didn't want to nore could I afford a new one. What would it cost to get it rebuilt, and how easy would it be to do myself? Heard manuals are easier than autos? Also the trans wasn't full, Speedo gear wasn't in all the way and have been told that could cause some strange noises. TOB is also 50 yrs old, but seemed to be in good working order, could the bearing be shot? sry for all the overwhelming info

wouldn't the input shaft spin or at the very least have some sort of play in it?

So for starters I'm not a trans specialist, but I have dealt with a handful of t-5's and specifically this problem. Also, with a press, a gear puller and a bearing splitter and some pipe you can pretty much get everything done. Lot's of youtube vids about this, just watch a couple and see what you think.
Anyway the loose bearings between the back of the input shaft and the tip of the mainshaft starve when fluid is low, they wear down the tip of the shaft or it'll be pitted. Also, check your input shaft play, for some reason almost all of them I've looked at off craigslist have been jacked with, lot's of input play and/or missing shims in the bearing retainer. It's just like any transmission auto or not, your endplay needs to be right, not more not less.

So, in the past I begged the guys at standard gear to sell me a good mainshaft, but that has dried up. I was told you can have them either welded or sleeved, but I haven't personally had this process done. Sounds like standard machine shop protocol so I'd expect good results. I have also heard about converting to the cobra tapered roller bearing, but I have no idea where you get those parts affordably.

I have a t-5 in my car now that has always been a little noisy, but I drove the fox body it was in for a while and never noticed anything. It's tough to explain relative noise on the internet, but this one is more like...yeah there is very little between me and that transmission. I have driven M5OD's that did sound like superchargers, to the point where people would look at you in parking lots. Take a real close listen at :40, you'll hear that t5 through a couple of gears. Compare that to yours, and I have many miles on this trans with no change in noise. Not saying it doesn't need repair...but I'll need to hear a lot more before I address it. I had to swap input shafts on this trans and I can't remember what the mainshaft looked like, but I would think if it looked bad I would have caught it but who knows. The second vid is just a teardown vid of the t5 so you can gauge your skills.

thanks drivedrinkgoto, I'll have to check out those videos when I have access to a computer. Already had checked the input shaft for play, don't recall there being much play if any, but that was back in July of 2012. I do remember the input shaft looked new (hell, the whole trans did) no imperfections whatsoever (looked over the trans thoroughly). Never did check the bearing. Can I get one at my local parts store, preferably Napa? Shouldn't run that much.

thanks

I am not sure about NAPA usually your local manual trans shop will have this stuff in stock. But if that's the problem, you'd just need the t5 small parts kit for whichever trans you have. I wouldn't buy anything before you tear it down.

tob noise would be the same in any foward gear and reverse.. my first guess would be input shaft or cluster shaft bearings are shot. using a 4cyl t-5 in place of a v8 trans could cause the shafts and bearing to wear and be noisy.. the cluster shaft is always being used except in fourth gear, it just spins with no load.. if the pilot bearing does not hold the input shaft in place then 1-3 gears would try to separate from the cluster and could whine due to excessive gear lash and poor contact pattern.. 5th and reverse gears are supported by the output bearing and tail shaft bushing/slip yoke.. next i would be checking the runout on the bell housing, factory ford bells seem decent for the most part, its the no name, aftermarket bells that may need to be realigned..
