Ok just had my 700r replaced. I'm putting in secondary tranny coooler today. Can anyone tell me which line from the radiator is the return line. Upper or lower. She's a 1990. Thanks.

trans cooler?
- Thread starter digity
- Start date
Bottom line into the radiator is in FROM the trans, upper line goes out TO the trans.
To confirm, start engine cold, place trans in drive for 10-15 seconds, shut off engine (put trans back into park!)
Touch lines at radiator. The "from trans" line will be the warmer of the two.
