Identifying Speed Sensor

[eclipse1501]

Ive worked out from threads here on prime that my speed sensor may be faulty, loose or bad connection as my speedo needle is doing cartwheels sometimes. I understand its on the transmission but can anyone tell me where exactly or how to identify the right part. Ive checked the online manual but its not clear amongst all the electrical illustrations. Thanks for any help!

Looking from the drivers side of the engine compartment locate the upper transmission mount. The speed sensor connector is to the upper right side of that mount, closer towards the engine. ( See page 13-6 of the service manual and zoom in on it) Good Luck!
