'97 Civic P0700/0715

[CorneringArtist]

So a coworker of mine just picked up an automatic '97 Si that was traded into our dealership. Vehicle for the most part runs fine, but the two codes in the topic do trip, and come back when cleared. We have tried using Honda-Tech to diagnose, but the answers are a bit vague since they all have differing opinions on how to fix it (it's generally ATF replacement ->solenoid replacement -> tranny replacement).

Before we decide to dig further, I was hoping someone on RS has dealt with the issue before. Any advice is greatly appreciated, thanks.

0700 just points to a transmisison problem. 0715 points to the mainshaft speed sensor in the transmission.
Good news is, it's most likely just the sensor fail. Worse case mechanical problem in the trans.
the sensor should have between 400-600 ohm's when checked with ohm meter. start with that
