I have been restoring my 69 Sears Super 12 and after flushing the sludge and old fluid from the trans, Im ready to re-fill it but not sure what to use. Its a cast iron rear with a 3 speed hi/lo. I have had someone tell me to use 80w90 and then someone say HD SAE 30. Anyone have an idea? Thanks, Charles
