My trans (46 3spd) has started to make some unusual noises. I know that these old transmissions tend to make a lot of noise but this is something new. It's making a moaning noise when I decelerate. It stops if I push in the clutch. I have checked the fulid level and everything else seems to be working perfectly.

Is this the trans or maybe the U-joint. I'm not sure what a bad U-joint sounds like. What should I check? Is this going to damage the trans?

Thanks George

p.s. This trans has been rebuilt, new bearings and every thing. All the gears looked good when I put it back together.

If it does it or is worse in the lower gears You probably have a bearing bad in the trans. If it does it in high gear I would take a look at the rear end.

Is it quieter in 3rd gear than in the other gears?

I'm pretty sure it's not the rear end. It makes noise in all gears when I let off the gas. Sounds about the same in all gears.

Hopefully it's not a bad bearing. I would hate to rebuild that thing again.

Any more ideas?

With a bad release bearing you should feel some vibration thru the clutch pedal. How did the countershaft look? The shaft acts as the "inner race" and excessive clearance could do it. Did you replace all the pins?
