Looking for a turbo tranny sensor

[hodunwun]

91 gs turbo: Need a pulse sensor of the auto tranny for this turbo. It's a two wire black plastic sensor right near the tranny dipstick. It sends tranny speed info to the tranny ecu. It is very simple device that the dealer wants 90 bucks for. It is held in place with one 6mm bolt. It is bassically a coil of wire around a shaft like and electro magnet. Junk yards around here will not sell it off a tranny. Does anyone have one laying around or in a bumbed out tranny case. It has number on the edge: x4t24075. Any help or referral would also be helpful.
