85 GMC K2500 4WD VinM 350ci

Automatic 3-speed Transmission. 4.10 gear ratio. not posi

How can I identify my transmission? I know its a 3 speed auto lol. it has to be turbo 400 or turbo350. In the past i have done a filter and pan drop but i dont remember what i told the part guy when i got the parts. I want to order pre-bent trans. cooler lines from LMC but im not sure what transmission i have.

How can I ID my transmission?

Thanks
