I own a 1981 Ford f100 with a 3-speed with overdrive top loader transmission. This is the transmission with the shift linkages inside the case instead of viable on the side. We recently took the whole transmission apart because I accidentally took the wrong bolt out when doing a fluid change. I accidentally took out the reverse fork bolt and had to take the gears out to get it all back in. Anyway, we put it all back together and now 4th gear gets really noisey after you run it for about 15 minutes. It only makes noise when under load. When I let off the gas, it gets quieter. It sounds like metal sliding against other metal. Can anyone help? I don't know what this tranny is called but it's been hard for me to find information on it. I added some photos below. Thanks so much for your help.
Fourth gear fork is at the top of this pic. It looks to be worn but i cant tell what it'd be wearing on.
