Hi Guys,

I'm going to replace the radiator on my '97 with a manual transmission. I ordered the factory replacement AC Delco radiator:

"ACDELCO 20889 {#20931, 52470606, 52474697} GM Original Equipment Info
FitsTrans. code MM6; CORE SIZE 24-7/8IN X 17-1/8IN X 7/8 IN, CODE KDM,BBK; 6 speed Manual transmission
OrCORE SIZE 24-7/8IN X 17-1/8IN X 7/8 IN, CODE KDM; 4 speed Automatic trans."

It seems it's the same radiator for both auto and manual transmission cars. Since I don't have automatic transmission oil cooler lines to connect to the radiator, is there a plug or something that will block these off?

According to Rock Auto, there's a separate auto trans part:

ACDELCO 21451 {#10449531, 21734, 89018594} GM Original Equipment Info
Trans. code 4L60-E; CORE SIZE 24-7/8IN X 17-1/8IN X 7/8 IN, CODE GBY; 4 speed Automatic trans.

Black RTV it is! Thanks!

Looks like that's for the 01-04 model years only, they don't list a separate one for the 97 model year.
