I have never had to take any of my t 5,s or top loaders apart, but on the old T 10 and T 85(same design on most stuff) we would take the detent assembly spring out an throw it away then cut down a piece of 1/4 drill rod to size between the detent balls so it could onyl be in one gear at a time. don't know what the inside of your trans detent looks like
