I have a 95 RT/10 that had the transmission replaced with new. Since the new transmission has been installed there is a reverse solenoid ticking noise around 5 mph. If I disconnect the reverse solenoid it stops. I replaced the reverse solenoid however it still has a ticking noise around 5mph, but it goes away above that speed. The reverse solenoid is still chattering where do I go from here???

Is that the slight ticking moise I hear right before I come to a stop? Or right after stop? Lasts a sec or two and goes away?
been drivin' me nuts!!!!! Why would there be a reverse lock-out?, pretty hard to get it in reverse goin' throught the gears!!!!!!

Snakebit-- yes that is the noise. It is the reverse lockout soleniod which is trying to pull in and out.I haven't been able to find the reason or how to track the problem. This issue didn't come about until the engine was changed.Any info would help as this drives me crazy too. I have the solenoid disconnected right now, but thats not right and I want to fix it. The few Viper techs around here just head scratch and shrug their shoulders.

Anyone have a fix for this? I think I just figured out what I have been hearing.

The solenoid allows selection of reverse below 5 mph and blocks selection of reverse above 5 mph. So as you cross the 5 mph threshold, it should click.
Since you are complaining, is it because there are multiple clicks that don't correspond to going above or below 5 mph? Or just because it's noticeable? (Even with stock exhaust, I am surprised at that.)
In any case, the dark blue wire leading to the solenoid is supplying 12V, the light blue/black wire is going to the PCM, which switches the ground connection on and off. If you want to "see" what's happening, you could jumper a light across it and know more about what's happening.

Another option (if it annoys you, or if for some reason you think the solenoid is failed) is that you can re-wire a switch to the solenoid so that reverse-lock-out is a manual function. put another way: switch on=grounded=reverse works. switch off=reverse locked out. Just don't valet part the car if you have this hidden switch...

It’s a ratcheting/clicking sound only at low speed (probably under 5mph). It does not matter if the car is in gear or not. I can barely feel it through the shifter (no isolator). It shifts great and has no other symptoms.

I just had a tech diagnose the sound as a failing throwout bearing?? Does this make any sense?
A slight ratcheting/clicking sound at very low speed, in or out of gear. I can't picture a bearing making any sounds like that at all. I would think it spins way too fast to click.
Car only has something like 5k miles and no track time.

The hydraulic clutch throwout bearing has a spring to keep the bearing slightly against pressure plate fingers 100% of the time (unlike mechanical clutch systems.) If the bearing were really bad, it would make noise all the time and might be drowned out at higher speeds. I would think you'd feel it in your foot more than your shifter.
It doesn't correspond to what you said about unplugging the solenoid - did the tech know this?
Long ago my reverse solenoid failed: the return spring inside the electrical solenoid broke, the pieces wedged the plunger permanently in one position, and when the PCM tried to turn it on and off, would do anything. One day I couldn't engage reverse and could even overpower it to engage reverse. Apparently that episode fried something either in the PCM or wiring and I never found where. So I wired the "mystery switch" to engage/disegage the reverse solenoid.
