I recently purchased a used Pnn3 transmission with an oem lsd and took it all apart and put all the internals into my case and replace all the Synchro‘s. I recently got it back into the car and everything works fine but I let off the throttle and coast I hear this whining sound like I’m in...

I’m looking for either a 5 speed or a 6 speed k series manual transmission to get my 2006 accord running again. I need something that is in working condition and runs. Seller must be willing to ship it to Florida Thanks!
