New to forum here and looking for advice on my tranny! I have the 07 3.8l grand prix with the 4t65e tranny if I'm correct? In the next week or so I'm plannin on changing its oil and filter and puttin in a new shift kit at the same time. Got a few questions here.....
1- i was under it today changing engine oil and noticed that 3 of the lines going in the tranny were leaking slightly. One was to the point where it had a drip on it...2 lines in the front. One in the back. Is this something to worry about? Easy fix? Parts needed?

2- also noticed the rack n pinion(thing comin out of tranny going to wheels) was seeping abit. At what point do you worry about that? Is that something that would be fixed at the same time i have the tranny cover down?

3-anything else to do while in there?

Sorry for the long post but I'm a newbie mechanic and just tryin to save some money by not taken er to a shop. Thanks for any help!
