Transmission failure

I'm new to forum and thought I would ask for advice on best next steps as my 5000 mile 2005 has tranny noise. Deer thinks it's pinion and or carrier bearings. After talking with RPM and others all I'm getting is "replace it". If it bearings I got to believe I can figure out type/size,etc
And replace . Open to any all insight, experience, etc
 
are you sure it is not just normal 'gear rollover noise' ?

This is the first tranny failure in so few miles that I have ever heard. I cant believe its a "failure". Does it have a tranny cooler? Have you checked and changed the tranny gear lube, and inspected the old fluid for trace metal, etc.? You may want to consider spectrographic testing on the fluid, which might narrow down the possible culprit.
 
As of today, our gearboxes are not that serviceable and replacement is usually required. The tranny "sometimes normal" roll over noise can be very loud in some cases but the gear box works fine. Questions would be have you experienced any shifting issues and is the noise only present at idle? Others will probably chime in who are more knowledgeable than I am on this potential issue.

Does the noise go away or lessen at idle when you step on the clutch pedal? If yes, this is normal. It is described in the owner's manual.
 
there has to be a way to reverse engineer some of these parts. the common wear parts like bearings, syncros and gears shouldn't be that difficult to have
re-made in my opinion. some of these wear issues are only going to get worse as time goes on. I keep hearing someone was going to do it but have heard that for years. I've tried to deal with Ricardo direct and they just keep saying the parts are proprietary to Ford which I've heard from a Ricardo engineer directly that only the case is a proprietary Ford part, not the internals.
 
bearings should be easy enough, hard parts gears etc can be made, but at wha texpense, Here in Aus we can get a gear set( that's a mating set say second gear) made for under a $1000. crown wheel or pinion wear, well that's another matter, wasn't someone making them.
 
this will be the first tranny failure that I have heard of in so few miles especially on what I would assume is a relatively stock car? another words I assume this car is not making more than 1500 hp?
 
Define "Tranny Noise"

The Ricardo Tranny makes a symphony of noises:

-'rattle-snake' buzz when lugging engine in too high a gear for RPM
-vibration cable/transmission tunnel buzz at very high speed (>90mph)
-Neutral/idle "gear roll over" noise; like a cycle / chain threading noise; louder after engine/fluids hot
-Pump noise: various noise emanating from water, fuel, oil, a/c, etc pump

In my book transmission failure means your housing-case cracked and fluid is all over or no power / free spin in a particular gear

Get it to a qualified Tech who can test it under load.
 
Headers, cat delete, X pipes make transaxle noises disappear.

you are right Gary. I didn't hear a single transmission noise from your GT when you passed me under the bridges on the Southfield expressway during Rally X.
lol
 
pretty sure, its most noticeable around 2000 rpm with a high pitch whine, when I engage clutch noise goes away .
 
no noise at idle, loudest at 2000 rpm, noise stops when I engage clutch
 
yes, noise gone at idle and clutch engagement, noise is progressively getting louder
 
I have spoken with Stillen in calif , they hold out hope that they have access to some tranny parts depending on what they are
 
totally stock car
 
very helpful, thank you. gear rollover best describes it, but I believe when I engage the clutch noise stops. finding a qualified tech is the big challenge who really understands and knows these cars
 
If the noise stops when you depress the clutch pedal, it's further evidence that it's neutral gear rollover, which is normal. Common to my GT500s too.

People sometimes worrie to much . It drives so drive it. If you take it to a mechanic you only will get more confused because most of them will just speculate what's wrong. Liston to us and the above post. And drive that thing . I just turned 30000 last week .
 
the GT Guys are the best, but post your location and the members can steer you to a reliable tech.
