The car sounded fine, no transmission noise, 27K on the clock. Then I started getting a loud rattling noise when the in neutral with my foot off the pedal. The car drove fine otherwise. I was concerned with the noise and found out the transmission sleeve was broken. Pulled out the transmission and put in a steel retainer. All new parts were used when I put it back together.

The transmission is still making a loud rattling noise in neutral with my foot off the pedal. After messing with the clutch adjustment I could not make it go away.

I read a lot of posts of T-56 and the "box of rocks" issue, but the transmission was quiet before the sleeve broke. Anyway I pulled the transmission out again and I don't see anything wrong with any of the parts. I checked the input shaft with a dial indicator and it is within spec.

I am not sure what to do next! Ideas?

Does light pedal pressure change the noise?

They are a little noisy. Kindof a rumbling noise if you’re in the garage where it echoes off the wall.

Maybe get it up in the air and listen.

Is it possible that you just weren’t hyper alert to the noise until now?

Yes, some pedal pressure changes the noise. Oh, this is much more than a rumble. It is very noticeable. I should have taken a video, but the transmission is out now.

Something similar happened to a friend. It sounded fine then one day he was taking someone for a ride and the trans started making more noise. He ended up getting it rebuilt and I think third gear had a couple broken teeth. Which is funny because out of all of us he's the easiest on his car.

I have been very easy on my car. I bought it when it had 12K or so and now it is about 28K miles. I don't know where to get it inspected/rebuilt locally and shipping it off somewhere to get it fixed could be an unknown cost. I might just get a magnum and be done with it.

Not sure where you’re at, but my Magnum is going to Hanlon Motorsports if/when it needs a rebuild.

Their customer service is top notch.

I took off the front cover of the transmission and nothing appears to be bad. I used the input shaft to check the pilot bearing and it fits just fine. I checked the clutch disk and the springs are tight and there is nothing loose.

I think I will order a 26-spline input shaft. It comes with a new bearing and race. It's worth a shot. I will have to get a new clutch, but I don't like the Lethal Street Fighter 525 that I put in. The release point is too high. They did not tell me that I it needed an adjustable pivot ball. I will get more widely known clutch kit this time. Wish me luck!
