transmission/oil cooler lines

[Ryanbrown36]

Hey guys, Im finishing up a Oldsmobile 5.7 diesel to Sbc swap and noticed my transmission cooler has 4 ports. I'm hoping to start it up this week in hopes of getting it on the road for a bit before winter and want to know what I should do with it. I'm not very knowledgeable about this stuff and learning as I go here so might be a dumb question. I'm just trying to get it started as soon as possible and don't want to spend money in the wrong places. from what I've read I can buy a new trans cooler with two ports, run a oil cooler or was hoping I could maybe plug those two holes. thanks in advance

Oscar this a factory cooler? Possibly a water to oil heat exchanger? Of so you'll want to run heater hoses through 2 ports transmission lines through the other 2. I personally would use a radiator with the built in transmission cooler and if I was going to run an external cooler I'd run transmission pressure line to external cooler,external cooler to radiator cooler,back to transmission. That way the radiator regulates transmission oil temperature so the ATF is not too cold

I am not sure if it is a factory cooler but if I had to guess I would say yes, I believe the two extra ports used to run to an oil cooler at the oil filter. I would prefer to not have to buy a new radiator if possible. My heater core lines currently run through the rad if that helps and all ports on the trans cooler fit a 3/8 hose.

If you have a radiator with 2 ports for transmission cooler,just run lines from the transmissiin to the radiator an forget about.

I would but my radiator doesn’t have any ports for the transmission cooler
