thanks for your reply bro. I took it to a shop today and the guy told me that the issue with the grinding was the tranny mount and the white smoke was coming from the seal or gasket of the transmission. Like i said before the grinding noise only happened when I was at a complete stop and then I would drive forward at the light about 10-15 ft and then the noise would stop. The guy also told me that i needed to change the cat converter and rack n pinion in the future. I just don't have the money now. He also told me that because of the seal or gasket of tranny thats why it's leaking onto the pipe and thats why I see the smoke. Is that true about everything he said? He told me he would replace the gasket and mounts with a oil change( not sure if engine oil or tranny oil) for $110 and $75 for the mounts thats with labor. Do you think this would resolve the issue?

did you ever find out what the problem was? im having the same issue, I just got my car actually today, and everything was fine until after I got he smog with the previous owner. The smoke is coming from underneath the auto shifter and armrest on my 93 300zx. Smoke comes in my cabin and I hear a grinding sound when Im at a red light and go when its green. The smoke comes also from the rear wheel well and right below the shifter. When I driving after the stop at a light, i hear no sound. What do you think it could be. I think our symptoms are the same..

Smoke Coming From My 1993 Nissan 300zx.. Please help!? I just got this car..When I test drove it, it ran fine.. no smoke, nothing... some dings here and there, but thats it. Anyways before I bought it I made sure it passed smog with the owner. I took it to a guy and it passed and failed. Passed visual.. Passed CO test..Didn't Pass NO test. The guy said that it was easily fixable and to give him $100 dollars and afterwards it will pass smog. I Left and came back and he gave me the paperwork and i left. i had my buddy drive the car to my house while I followed in my car. When we got to my house I drove it to my dads to show him. On the way about 5-6 miles from my house all of a sudden all this smoke was coming from underneath the car. The Temp was normal, no check engine light, nothing. I get off the freeway and pull into a gas station. I look underneath the hood and no smoke was coming from there. I drop down to the floor and notice that the smoke was coming from exactly between the back of the engine and I think the tranny would be. It was exactly underneath the automatic shifter and the armrest would be. There was no leaks coming from underneath the car. All I seen was white smoke coming from that spot between the motor and I think the tranny. My buddy told me to move the car forward. He noticed that there was 2 little droplets of liquid on the floor. It was pink in color. Called the previous owner furious and he told me nothing should be wrong, and that the smog place must have did something. I drove to my dads about another 5-6 miles and on the way I was hearing a thumping almost grinding sound coming from below the arm rest only when I would be at a complete stop and then drive. After I drove for a second and picked up speed, I wouldn't hear that sound anymore. The car smoked still as I got there. Dad told me not to drive it anymore and get some tranny fluid. Bought some and put some in and car was still having the same issues. Grinding at a complete stop from underneath armrest just until I picked up speed and smoking from underneath the car. Just to not make this story long, what do you think the issue could be? SYMPTOMS: 1: White smoke coming from between the back of engine and believe tranny ( below auto shifter and armrest) 2: Noticed pink droplet on the floor (believe its tranny fluid) 3: Grinding at complete stop when I accelerate. When I pass 10mph or lets say 20-30 ft it would stop. I need help.. what can the issue be? Possibilities: ( Dad Thinks) Tranny mount, Tranny pump.. Can this be it?or is it something worse?
