hi, i have a 02 grand caravan with a 3.8 od when i put it into reverse it makes a vibrating sound. you can also feel it. it also did it in foward a time or 2 but mostly when shifting from park to reverse. but not all the time. i replaced the solnoid block on the front of the trans with a new mopar. it was good for a few days but now it is back what could it be? thank you for any help you can give. the trans has about 70,000 miles on it oil changed evry 30,000 van has 168,000. 10,000 miles on oil new solnoid pack has about 150 miles on it

 

I have the exact same issue, also have a grand caravan from 02. Spent last night laying under it reproducing the clinking noise trying to figure out where it was coming from. It happens every time the wheels change direction (forward to reverse) or sometimes when you break suddenly. Couldn't figure it out so now im looking online.

 

Welcome to DF
To our new members. The clicking sound, Does is sound like a ratchet?

 

mine does not sound like a ratchit mine is more of a growl slash vibration

 

it sounds like the solnoid block on steroids when it happens but that is a new mopar what else would make a noise like that

 

My sound is a clicking, so probably different from jeepmans. Unattached the rack and pinion from the car, it's still in there but i'll get it out tomorrow. I think there is a crack or some sort of break somewhere between the inner lie rod and outer lie rod causing the noise every time the direction of rotation changes.

 

mine does it going into drive now to and it did it 1 time just stoped in a parking spot still in drive. i think i might have a wiring problem but do not know for sure was told to look under the battery box the harness gives trouble there but i do not know

 

Have you check all the motor mounts and the 1 1/4 axle nuts?

 

checked all mounts and axle nuts it is getting worse i would say it is more like a shudder now when going into gear. almost like its going in out real fast do not know how else to describe it does it going into drive now as well i think it must be electrical but not sure. what about speed sensor could one read wrong and still not throw a code?

 

If output speed sensor problem, the transmission will go into limp mode and the speedometer won't work either. Because of the weight of the thick wire harness there can be a lot of pull on the output speed sensor wires. I lenghtened mine (2002) just in case.
Perhaps electrical connection at the solenoid pack should be checked.
