I deleted my oil cooler. The crappy push connectors leaked even with new lines. The older trucks had threaded fittings on both ends.

You probably need 625-139 and 625-140.

Re: LO5 V8 coolant lines and transmission line

Those are the two options I thought were the best. Delete the oil cooler with an oil filter adapter from an engine without it. I had one. Or use an oil filter adapter from an older truck which has threaded connectors instead of the push ones. I also have one of those, but I didn't want to buy lines so I deleted it.
