its by your intake manifold on the bottom of the engine block. there is a heat shield covering it which will need to be removed to get to it

I have a 95 Eclipse and I recently had to change out my TCU........ Transmission Control Unit, This should be located directly beneath the center console. First I would have the transmission services if problem persist then proceed to changing out the TCU you can get off of ebay. As far as i know there should be 3 Computers in our cars. 1 the Electronic Control Unit located behind radio 2 Transmission Control Unit located under center console and 3 Airbag Control Unit located under hood, Hope this helps.

You can take your car to Auto Zone and they will scan the codes for FREE. They will also let you know the part causing the problem. 99% of the time it's a sensor that you may be able to replace yourself if your handy with cars. Without the codes, it's random guessing to fix the problem.

it's right adjacent to the cataytic converter

I just went through the same problem this year twice. My car started smoking some, and I notice a trial of fluid on the road both times. I'm not sure but my car problems may have started when I got my Transmission flushed.

My car has 100,000 miles and I drive my car pretty hard.

I was first told the torque converter went out. Then I was told the Fuel pump needed to be changed. After being without a car for threes months, I just brought a new transmission and had it shipped to the shop.

From researching online, I think the fragile "Wave spring" in the transmission needs to be replaced and the new version of the "Wave Spring" is a solid & thick metal ring.

Secondly, the Mechanic will need a alignment tool to put the transmission back together properly. The tool is called Sonnex or made by the company I think.

Let me know what you find out.

Also only use Transmission fluid for Mitsubishi Eclipse only.

1. Torque Converter
2. Transmission "Wave Spring" broken pieces of the wave spring may damage other parts as it flows through the system or the fuel pump I think.
