Common issues with the rubber part of oil cooling lines for engine oil and transmission. Leaks at connections. I cut out old rubber and install 3/8 inch 400 psi hose with 2 clamps on each end. A cheap but permanent fix. New lines if installed will just leak also... rubber part is flimsy and crimp not secure... risk blowing out and losing engine oil will cause engine failure. You can install block off plate for engine oil cooling lines and eliminate the lines completely for $10. Not needed. See youtube for fix.
