Why would my 06 chevy impala leak transmission fluid?

Hello, hard to say - hands on testing and evaluation is needed. If the transmission for some reason overheated, it could have pushed the fluid through the front shaft seal. This could be due to some kind of internal transmission issue. If the leak came from some other source, it needs to be identified for possible repairs also. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
