Thread: Installed new 2800 stall - whining when in neutral

Tweet

Guys,
I finally got around to swapping the 4000 stall out of a '69 Nova that I just bought. I put in a 2800, but when all was bolted back up and we topped off the fluids and ran it through the gears a fairly loud metallic "whine" happens when in reverse. The other gears were all quiet. We decided to take it slowly around the block when we didn't see anything leaking, couldn't find anything we forgot, etc. It ran great and responded very well at driving speeds (unlike the 4000 race converter), but started making the sound in drive as we approached my driveway. I even thought that maybe the trans brake was the culprit, but it works fine.

Any thoughts? This was the last thing I expected to happen.

Thanks everyone...
