Hi All,

I'm being told by the shop that my truck is at, that my transmission (700R4) makes a whining noise, and only in 4th gear. Any ideas on what could cause it? I searched and didn't see any threads regarding a noise like this in a 700R4. For what it's worth, It is a low mileage transmission, that has been stored for close to 2 years in my garage. It was just installed in the truck along with my engine, and the original drive line that was rebuilt and modified to fit (truck originally had a powerglide). They added a new filter and all new fluid while it was being installed. I haven't heard it myself, I'm just going off what they've told me. They also say it shifts just fine, with no other noises.

Thanks for any input!
