Hi there,

If you are still getting coolant in the transmission, then I would replace the radiator.

You may also need to replace some or all of the coolant hoses, since you will also have transmission fluid in the cooling system.

And flush the cooling system.

Once there is no fluid cross contamination, then do the trans flush twice, the opel trans fluid is better.

Hope this helps.
