The cooler line has a leak but not that bad,(see pic with red circle) the one from the transmission to oil cooler. Do I need to drain the oil before I could replace the whole line OR can I just loosen that bolt and put right back? Share your thoughts on these.

Is it leaking from the fitting, the hose or the pipe?

It will drain out when you replace it anyway. I would drain before you repair the hose to avoid a mess. You will need the replacement bass ring for the trans plug and new fluid.

the leak is between the rubber thing and tube. see pic with red circle. Thanks for your input.

I am sure I have to replace all the necessary O-ring and the likes all at once. what kind of oil is being use on this - transmission oil?

Mobil/1 qt. synthetic automatic transmission fluid This is what I use.

dewdaltz

thanks. one more thing how/where do you add the transmission fluid?

Add it using the dip stick tube you will need a funnel that fits. Also the transmission will have to be around 100 deg. before you can top off.
