EFII High pitched vibration on changedown
hi everyone, got a question for ya's
i've recently bought a '96 EFII Fairmont and when i really stick the boot in (say to accelerate getting on the freeway) the gearbox changes down a gear (good so far) and a high pitched squeal or vibration is heard. sounds like it may be a bearing spinning or similar. the sound doesnt happen on average acceleration, but only when i really flatten the accelerator pedal.
any clues would help b4 i go to see the local transmission guy. thanks
