My tranny started making a terrible hi pitched wining the other day and i was wondering if it could be the oil pump in it. Apperantly one of the tranny lines got crimped pretty badly and i took a drive on the highway cruising at arund 65 for a good 1.5 hrs. I didn't notice the noise till i got off the highway and slowed down (i can't hear much over my exhaust cruising at those rpms). It doesn't start wining till it gets good and warm, at least 10-15 minutes, and when you shut it off you can hear change pitches as it slows then shuts off. I was wondering if anyone has any idea what it could be, i was thinking i might have starved the pump and burned it out. It still drives with out any other noises or problems( no grinding, slipping, etc), not that i've moved it farther then from the street to the garage. Any input would be appreciated.
