ok after a very long week trying to get my 260e started after it has been at the worst shop iv ever took a car to i got it started. well every few revolutions of the engine theres this bad friction noise comming from the bellhousing area i believe and whenever it happens it kills the engine. and when i go to shift to any gears it does absolutly nothing no engaging what so ever. it was at the shop for a complete drivetrain repacement and judging by the way i got the car back from this idiot i thing he put something together wrong. its also leaking transmission fluid from the bellhousing.
