Anonymous, It sounds like you have a bad speed sensor on your 300ZX as these sensors provide input to the ECU on when to shift your transmission.....Figure out where it is and replace it and your problems may go away.

A loose connection to the starter; Bad battery; loose battery cable; bad ignore switch. As the dash lights disappear, it indicates a power failure in the system. Start at the battery, follow the power point checking for power atdifferent intervals,

pop the rear deck lid and remove the right rear plastic trunk cover. To do this you will remove the small plastic piece that is directly in front of the right rear tail light. Then remove the big plastic screw that retains the center plastic deck lid cover. Now remove the three 10mm nuts that keep the right rear plastic cover secured. Remove the right rear plastic cover. Be careful as it can crack if you put too much pressure on it. Look inside and to the right rear where the antenna mast comes up. You will see a small 10mm nut that holds the antenna mast to the body. Take that nut off. This will release the outer body cover from the inner cover. Remove the outer body cover and then remove the two screws from the OUTSIDE of the body cover. Now follow the antenna body down and you will see two or three additional small nuts that hold the antenna assembly metal bracket in place. Remove these. Unplug the antenna co-ax cable from the input. It just slides out. Unplug the antenna connection as well. This is the jack that has the power wires. You will also need to unscrew the ground wire from the inner body frame. There might be a nut on top of the actual antenna mast. If so, just unscrew it. The entire antenna assembly will now lift out. It's a mildly tight fit but you don't need to be too gentle in this step. Normally the problem is the antenna belt has broken inside the antenna assembly and there is no hope of replacing that belt. You have to replace the entire assembly. I found mine on Craigslist from a guy parting his totaled Z. May it rest in peace. His loss - my gain! Typical price is $65, maybe you can talk him down to $50. Installation is the above process in reverse.

If it's leaking,need to replace it.

Sounds to me like you had an electrical burn out or near fire condition. Water may have gotten into an open area like wiring harness or fuse block and caused a short and what you were smelling is the insulation or other plastics burning. I would take the car to a auto electric specialist for diagnostics.

What is a twin turbo automatic? are you talking about the engine or the transmission, what is bad and what are you trying to find out will fit?

duplicate question

Nope.Any time the system is disabled, the light is on.You would need to have someone access the system module to get the code or codes to proceed. The system problem would have to be fixed to make the light go off unless you remove the system from the car.

It is built into the main engine control processor called the PCM and it talks to other modules, so it is not just one part.
