I am wondering if anyone can help me with my problem. I have a 74 duster with a 360 and a 4 speed. The other day when i went to back up the car as soon as i put the car into reverse it makes a noise even with the clutch still pushed in. to describe the noise i would say it kinda seems like the starter running. but i know that isnt the issue. it only does this when it is in reverse. any pointers as what this could be thanks
Possibly a bad bushing on the reverse gear or bad reverse shaft. I'm just thinking in my head how the power flows through reverse. I guess it could be the reverse fork too. You mentioned with the clutch pushed in, but is it coasting in reverse?

Your last comment says it will continue to make the noise when the clutch is released - in neutral or in gear ???
I doubt the problem is inside the box. That leaves the pilot bushing/bearing in the back of the crank or the throwout bearing.
I doubt its the pilot bushing/bearing as this ONLY sees use when the clutch is depressed and the trans is in gear (the input shaft is not spinning and the crank is). Since the crank and input shaft are always turning at the same speed when the clutch is engaged there should be no noise from that.
So that leaves the throwout bearing and this is a common enough problem. I can't tell you how you'd pinpoint it precisely but I can't see it being anything else given your symptoms and explanation.
A replacement is about $50 but requires the removal of the trans. Pull the driveshaft, undo all shift linkage, remove the shifter, undo wiring, undo speedo cable, support the rear of the engine, remove trans crossmember, lower the engine/trans, pull out the trans - STRAIGHT OUT or you screw up the clutch. Now you can replace the throwout bearing and put it all back together.

the only wires i can find is there is 2 wires that hook into the transmission. if i disconnect one of the wires it wont make that noise in reverse but it wont start with the key i have to use something across the starter relay. could it be that sensor on the transmission bad.
Sounds like your relay maybe fried. Check to make sure there isn't a voltage going through the neutral safety wire at the relay

ok i found the issue. someone had the wires wrong. they had the ground wire running to the reverse switch so when i would put the car in reverse it would send signal back through and short out the relay. the diagram really helped out thank you greatly
Wow, never would have guessed that in a million years!
