I am in the process of replacing the transmission cooling lines on my G/A. Is there a way to remove the rubber seals from the transmission housing where the two lines attach to it without using the special tool (J-41239-B)? I tried removing the seals by hand but am unable to and I believe I have damaged the original seals enough that there is no turning back now. Is there any way of doing this without the tool or is there some kind of work around? Help!
