A904 Leaking thru speedo

Be thankful you are in Arizona. Just did my 904 o-ring in my 45 degree NY garage. Quick but messy job. Have a big tub for the trans pan. Drop low corner and let it drain for a while. Make sure pan is not bent. Replace with factory mopar rubber gasket. Will never leak again.
Thanks yes the weater is good to do this work here. Thanks for the advice! I hear the factory gasket is good.
