Hey, First off i have a 5 speed 84 305 z26, ive been having problems with it latley. ive been hearing this weird sound, like a whine coming from the transmission while excelerating slowly or keeping steady pressure on the gas. also when im in a gear ill give it hell and my rpms will shoot up and the car will vibrate and barely accelerate. i dont know if this is the tranny going becuase its slipping or maybe the driveshaft is loose, because i put new shocks and springs on the other day and after that is when i first started noticing the "slipping and vibration" i checked the tranny fluid and its full. has anyone else ever experienced this before, or maybe do i need a rebuild or a fresh fluid change? any help would be appreciated.
