OK MORE TRANSMISSION PROBLEMS

I got a call to move 3 trucks this morning. Left the neighborhood (empty trailer in tow), 1st, 2nd, going into 3rd holy **** it feels like the driveshaft just fell out. Pull over on the shoulder and even sitting still in neutral its still making a hell of a noise, put the clutch in and it goes away, clutch out its back (even in neutral). Limp it back to the house and here it sits.

I am not sure if the part of the clutch came apart and is being slung around in the bellhousing or if some other retainer in the transmission came apart or if something else in the trans just plain broke but something is majorly up this time.

The fact that the clutch stops the noise is interesting. Noise is too loud to be a release bearing. Idling and inspecting from underneath noise is loudest at bellhousing area. I doubt its splines stripping off an input shaft or anything as I was able to drive it roughly a mile without it getting any worse. Noise is moderate at idle, a little more pronounced in 1st, even more so in 2nd, 3rd literally feels like something is coming apart. I havent even tried to drive it in 3rd it felt so bad.

Maybe flywheel or pressure plate? Seems like that would make noise with clutch out, in neutral, but with clutch in the release bearing takes the load. The flywheel/PP would be under progressively more load with each upshift, and that seems to fit my symptoms.

 

Only way to find out what happened is drop the transmission.

 

OK trans is out, left the clutch on the flywheel for now as the when I spin the input shaft on the trans by hand it is much tougher than it should be and will even bind up- looks like the culprit may be in there. I think I am going to have a local transmission shop tear it down and see whats going on.

 

If your that far, may as well replace the clutch, throwout bearing, pilot bushing, and grind the fly wheel.

 

Clutch, flywheel, etc all look less than 6 months old. I am planning to inspect everything before I put it back together if I can find a lineup tool.

By the way, broke official diagnosis is a couple missing teeth on the 3rd countershaft gear. At least I think its third... anyhow looking for another transmission now.

 

Ouch.

 

Does anyone know a trustworthy place to buy a rebuilt/reman transmission from?

 

We have them rebuilt locally. This one shop has been doing our 4500 and 5600 rebuilds for years. That said, shipping on a 300lb transmission would be a little stiff from coast to coast twice. We can get you all the parts, though. Any gear or anything can be replaced. Get a list together of what you need (bearings, seals, syncros, ect) and get with me.

 

You might check with All Star transmission in Tampa Florida. I have bought parts from them to rebuild some fords and they are good people to deal with. They rebuild and ship them everywhere.
