wtdash Posted August 29, 2019 Share Posted August 29, 2019 google the part numbers. The one in yours now, the TZ1b7L...shows out of a '05 Legacy. I'd be surprised if that actually worked....and apparently it doesn't since you're asking. Your main issue is that '99 was transition year for many Subarus. Phase 1 vs Phase 2 electronics, engines, and transmissions, so you'd need to find an exact match, I'd guess. TC1A37C2AA (nor tZ1a37.....)= not a good number... nothing found in Google. TZ prefix usually means Auto; TY usually means Manual. LOOK on the VIN ID tag by the Driver's strut tower under the hood. It shows your engine and transmission.
