changing lower trans cool line seals Topic is solved

Need to change O-ring and seal on lower (output) auto trans fluid cooler line. If I were to not drain at the trans, but instead removed the lower cooler line at the radiator, it would seem that I would only lose, maybe, 2 quarts of fluid. Might I be correct? And, any reason why this might be a really stupid idea?

Thanks, DaleL

Look closely at the bottom line, you will find that it is downhill to the sump. There should be very little ATF in the radiator with a cold engine.

Once you start the engine, there will be close to a quart of ATF in the radiator and lines, I do not know how fast the ATF will flow back into the sump after shut off.
