Transmission Fluid Change - Royal Purple

Ok, decided to do the change myself.

Read it made changes smoother, and after doing it, it's a nice and noticeable change.
Almost consider it a Must Do.
Couldn't really grasp by what people meant by "smoother" ,but much akin to going to the dealer and shifting a new car. Almost.
There was definitely an "oh wow" on the first shifts.

17mm socket
Grab a breaker bar, I tried without, and it was really firm.
Not an issue at all with a Breaker Bar.
Mine's 18 inches.
(Don't get a chance to say "Mine's 18 inches" often, wasn't going to pass it up)

Used 2 bottles of the Royal Purple
And a Plews 5501 Quart Pump , which is under $8.00

Nice quick easy change.

Final Note
Royal Purple looks nice, sounds nice ... does not smell nice. It Stinks

You would/could say that ... I bought 3 bottles, and the pump at the link above.

Neither of the first 2 bottles "completely" emptied so I used part of the 3rd ...

When finished, I poured the remains from the first 2 bottles , into the 3rd, and it fit.

Depends how much you spill, if you're really neat, and have a better thing that that pump.
Two bottles would do.

That pump was usable, but the hose that goes inside the bottle, did not go all the way to the bottom of the Royal Purple bottle.

great to hear you're having a success and what I'm wondering about is the long term affect of using Royal Purple, thanks to anyone who can share this information.

Why not try a search? Do advanced and throw the username LSCMan in that box. There is very detailed info on tranny oil already posted by experts who no longer post.

I've read that royal purple is ok in the differential but to never use it in the m5 transmission....long term effects are bad...I think it's from the additives or the high levels of zinc or magnesium in the royal purple....don't remember exactly reasons but if you search on Google you will see
