    Is there a step-by-step thread on rear bumper removal/gear oil change?

    I've found threads on how to remove transmission screen...but not one on how to remove the rear bumper for the service. I'm not currently looking on drilling a hole in the diffuser to access the screen.....as I feel I need to get into and see everything first.

    Thanks for any help.

    Been through the gear oil change yesterday. I was actually planning to make a hole on the bumper for accessing the filter but I found out that I have not much leverage to remove a tight filler plug with the bumper on...so off it comes.

    Took the bumper out and it was easy removing the fill plug with more leverage. Also, the delivery pipe to the heat exchange is advised to also be removed to clear out any stuck oil in the heat exchange. This wouldn't be possible with the bumper on.

    In addition, it is recommended to remove the rear grill and to remove the grill the lights needs to come off. HOWEVER, after removing the rear grill it looks like if you have a small hand you can simply remove the rear tail lights and access the 17mm bolts behind the bumper through the holes where the tail lights are installed.

    I do mine without taking off the rear grill. There are two 13 mm nuts on each side of the rear bumper inside the wheel well. Then there are four larger nuts on each side way back just under the rear grill. I can get to these by going through the rear of each wheel well.

    Once those twelve total fasteners are undone, the bumper slides out.

    This is what I thought after seeing the bolts at the rear of the bumper. Oh well, I already have the grills and tail lights removed.

    Thanks for the links and information everyone.

    Follow up question: After removing wheels/bumper, do you put the wheels back on and lower car to ground to get proper dipstick readings? Is there enough room w/ bumper still off to access the fill hole and dip stick while car is back on ground?

    I just changed the gear oil last weekend. I elected to drill a 2 3/8 hole and use the rubber plug from Ricambi. The screen was very clean. It was very easy to remove and replace.

    That's what I did.. and those two 17mm nuts on either side holding on the bumper.. I found it easier to get them off with the screen off.. but you could go through the wheel well.

    FYI.. when you put the bumper back on, tape the body at the sides above the rear sidemarker lights. It can get scratched when you put the bumper back on.. ask me how I know! :(

    Did the gearbox work today. All of the information provided was invaluable.

    A couple things that I had different, were that I had four 17mm bolts in each side, not two like I read everywhere else. You can see the four hole bracket just above the exhaust pipes. I wonder if my bumper had been replaced at some point?

    Screen filter had some metal bits, screen was intact, date on it was 2001. I had bought a new one from Ricambi (2013 date) as a back up (had to replace engine oil screen last year.....) and noticed the seal on the new screen was located in a different place compared to the old. Hopefully that is just how they are made....it made it easier to reinsert though.

    Bought a pump on Amazon same time I bought the Redline oil, seemed to work well, possible alternative to a long hose.

    Removing the bumper is easy enough, just took a long time. I considered drilling a hole like many have done, but I don't see how you can get the to the fill dipstick any get an accurate reading w/o removing bumper.

    Thanks again for everyones opinions, suggestions, and photos.

    It's the copper plug in the middle of the photo with a steel braided pipe attached to it.

    It's the best photo I can send. I literally took Falcon Wing's photo and cropped it.

    Mine is the same way with 4 bolts. I always wondered if it was a 1999 thing, but yours is newer. I don't think it means the bumper was replaced, because that wouldn't explain the 4-hole bracket.

    I see that in your previous post now....wonder why the difference?? A couple of those were tough to reach! Glad I have a long extender.

    Yeah, a slightly more difficult removal, but I rest easier knowing my bumper is more securely attached than other's, lol.

    It's easy to read the dipstick, but the aero tray has to be removed. I went the drill a hole route, and do the tranny flush when the aero tray is off along with the rest of the fluid changes. Gravity filling the gear box with a long tube saves mucho time vs. pumping. Looks like you did a good job.

    "Reading" the dipstick is easy once: you jack up car, remove wheels, remove under tray, wheel well liners, remove bumper, replace wheels, lower car (to get a level dip stick), drain fluid, remove and clean mesh filter, replace filter, s l o w l y add fluid (pump worked great to get level correct), warm up car, go through gears, let fluid settle, check fluid level, replace dipstick, jack car back up, remove wheels again, replace bumper, replace wheel well liners, replace wheels, reinstall under tray, lower car.... ;)

    I just had my car in for service at Maranello Motorsports, they checked the fluid level and it was just fine. Glad to know after several months its still good.
