So, I suspect the throwout bearing might be going as it is hard to downshift from 4th to 3rd unless the rpms and speed is just right - this has been going on for about 3000+miles. Now, I have an oil leak (getting under car in a minute to figure that out) and all of a sudden car is making this high pitch whistle/whine noise, but only in 4th, and only when accelerating, if I let off the gas for a 1/4 second noise goes away, comes back when I push the gas. no noise at high rpms in other gears or neutral.
Is this the TO bearing, or a transmission issue? I always appreciate the help from USMB. Thanks folks!
