I can put it in gear but it won’t engage

Honestly, it looked pretty clean. No noticeable debris, no metal shavings. There were some granules in the fluid itself. Very fine like you would find at the bottom of a coffee pot. I took that to be due to the age of the fluid, as it has not been changed for some time.
If it is the pump or the converter you are saying it would be better to take it to the shop?

I’m not against taking it in. I would like to locate the problem first though. If the torque converter goes bad it’s usually due to overheating isn’t it? Prior to this problem I have not really had any issues with the transmission. No overheating, no leaks, or no slipping. I’m not a great mechanic so I’m not looking to overhaul it or pull it myself. I’m just looking for information. Thanks

Copy that. I will take it in. Thank you for your assistance.
