JD 550 oil cooler issues

[TOLEWIS]

I have a issue where coolant is getting into my transmission. I was wondering if anyone had installed a aftermarket cooler for the transmission and just bypassed the radiator. I was thinking of just adding a piece of hose to connect the two cooler lines coming out of radiator. That should contain any leakage from the radiator. Just trying to figure out a solution with out pulling radiator. I'm reading its a struggle to those repaired.
