My 73 Nova started leaking transmission fluid from the transmission dip
stick tube. It's a TH350 behind a 454. Took me three hours to get the tube
out of the transmission today. And, no way can I remove the tube from the
car, but I can replace the O ring. Question is how the hell am I going to
get he tube back into the transmission? Any hints would be greatly
appreciated. There is very little room to work as the header goes from the
sub-frame to the trans pan. Need to find a way to pull the tube down hard.

To remove the tube I tried to slide the rear cross member back to drop the
tail of the transmission. The cross member hits the right side header
flange, so I removed the rear mount and set the tail directly on the cross
member. Used a long extension and a swivel socket to remove the bell housing
bolt that also holds the tube. Then I could wiggle the tube, but no way
would it come out. After much prying and tugging it popped out. Then I
couldn't get it high enough to clear the transmission. The end of the tube
that fits in the transmission is long. After more wiggling and twisting I
found the right spot and it's out. What a way to spend an afternoon:(
