Ok I have a 72 chevy pickup with a 350 v8, auto 350 turbo trans. Motor and trans are stock. Last friday going about 70 mph down highway, the carter pin holding the linkage, washers, and spring broke some how and the linkage fell out. While this was falling out it shifted the truck into reverse. So Im doing 70mph with the trans in reverse. I got to the truck to the shoulder and put the linkage back together enough so it would hold in place till I could fix it. I fired back up the truck and drove off. Trans shifts fine and down shifts fine, no problems. Ran though all three gear and still no problem. Well I got home and fixed the linkage problem. Didnt find any leaks in the trans or rearend. Took it out again and found a problem with the trans...

I have a clicking sound in the trans when I let off the gas just rolling down the road still in drive. But it stops at 15mph everytime. Long as Im on the gas the clicking noise goes away but soon as I let off it comes back. This happens no matter what gear Im in. I can be in park and dont hear it, but soon as I go over 15mph the noise comes back. The noise sound like a kids noise maker for birthday parties and such. Like a gear hitting a piece of plastic. By the way I checked the fluid for both the trans and rearend, also the plastic cover over the fly wheel. All of these are good.

Anybody know what the problem could be?

Don't feel bad, I did the same thing once. Anyway I'm just going to take a stab at it and say that it is probably the roller clutch. At any rate, drive it till it pops, or rebuild it. You are probably better off doing it now, before it grenades and takes a lot of hard parts with it. If you are mechanically inclined at all, you can do it for about $150 with the converter. Any hard parts are fairly cheap for that trans. There is an excellent video out there, from Tecnical Video, making it definitely a do-it-yourself project.

Is there anyway to tell when the trans is about to go? Will the sound get louder? Or will it just go out when ever it feels like it? Well this is the only car I have at the time. My shop is 3.5 hours away from the spot Im in right now. Just asking will driving the truck on the highway for long distance hurt it long as its not shifting or is the roller clutch active all the time no matter if it is shifting or not?

Bad thing is the trans was redone about 3 years ago. Well that was a waste of money.....Thank you for the reply now I have a idea and somewhere to look.
