1966 Toro torque converter help

[60s GM Guy]

Recently my 66 Toro developed a whine and shutter from 1st gear into 2nd gear. I took it to my local shop and they said it was being caused by the AC compressor clutch being out of round. They removed the belt and then did a trans flush. I get the car back and immediately I see that its still doing the same thing, but not as bad. I take it back and three days later call the shop. They said they found metal particles which looked more like a metal paste than parts. The recommended a new torque converter which I sourced through these guys (https://floridatorqueconverters.com/Gen ... -34-1.html). Does this appear to be the right type of torque converter? Based on my receipts the previous owner did not replace the torque converter when the transmission was rebuilt in 2016. The car has 82k miles on it but everything mechanical (except the torque converter) has been rebuilt. Any help to solve my issue is greatly appreciated.

A new switch pitch torque converter has been purchased from Florida Torque Converter. Hopefully this fixes my transmission issue.
