I have an 85 245, and I'm hearing a whirring type sound, that seems to be coming from the back. It's like the noise you hear when you're downshifting, but it's not based on the clutch or gear-shift. It seems to be worse when it's cold, and seems to be more based on the speed of the vehicle, and not the rpms' of the motor. If I put in the clutch, it doesn't make much (if any) difference. I hope it's the power steering pump (which I'm replacing this weekend). I'm thinking it might be the clutch cable, but i havent' checked that yet. How do I check the fluid level for the tranny (if you do?)?
