Never too soon to change your fluids(oils). What could it hurt? Its cheaper than a new trans. Change it and report back. Maybe try Redline's MTL that everyone is raving about.

So I swapped out the transmission fluid last weekend and replaced it again with Redline D4 ATF because I had extra lying around from last time.
The world seems right again. Shifts are smooth and effortless. I used to have a weird situation where engaging the clutch in first gear was rough and it felt like the clutch wasn't smooth or something. The car would sometimes stutter when I let out the clutch. After changing my oil, transmission, and diff fluid all at the same time last weekend, that jerkiness/clutch uneven sensation has gone away too. |

Just did this. This how to was handy, but I had the same thought as a few others, having changed the MTF on other vehicles, why not let gravity work for you. So I ran 3/8" tubing (thanks Joe O. for the size) from the engine bay downwards. Only snag, was when the tubing literally snagged against the chassis at some point and began dribbling out fluid as I was pouring it. Oh well.
Swapped in Redline MTL, having used their products with success in the past. Verdict is out on the difference in feel, maybe a bit more direct, but that's about it. Old fluid had 30k miles on it, was brown in color, still smelled like MTF, which is to say, nasty.

Just did this recently and the DIY came in very handy, especially for torque settings and such. Went with Redline MTF and there is a noticeable difference in shifting smoothness. Really nice. Used the "tubing method" to fill from above, just under 2 quarts to fill. Used 1/2 inch tubing, was a perfect fit in the fill hole on the trans and the 2 quarts went in amazingly quick.

Hey everyone, my rear diff seal or axle seal is leaking, so I'llbe bringing it in to my mechanic for a gasker/seal replacement. Since this involves draining the diff fluid, what weight oil is recommended for it? It's a 2011 135i dct. My mechanic loves to a royal Purple, but has various weights, so not sure which is good for this car.

BMW uses Castrol SAF-XJ or SAF-OX 75w140 GL5 gear oil. Lots of guys have been using Redline 75w90 GL5 gear oil - with no problems. See what your mechanic recommends. ? Dackel

Thanks Dackel. I dropped the car off. My mechanic suggestsed the 140weight as it'll provide more protection for me since I will be tracking the car 4-5 times per season.

My transmission fluid at 17,450 miles next to fresh MTL. Meant to do it much earlier... Oh, and added a Dimple plug though swishing through the old fluid with a magnet yielded no particles.

Have you thought about sending a sample for testing? Color doesn't necessarily indicate oil life, unless it has a burnt smell to it. |

I might. I wasn't having any issues; I had really meant to do this as a break-in change at 1200-2000 miles and kept saying "tomorrow, tomorrow."

Gotcha. I believe I have read some research though that on transmissions, most metal wear occurs in the first 5-15,000 miles, so you're probably still good with regard to break-in.

Does anyone know what the size of the gaskets for the manual transmission plugs and differential plugs are? Also, does material matter? Aluminum, copper, etc?

After further research, its recommended that the entire plug (including o-ring) needs to be replaced after each service? Seems overkill...what do you guys think?

But I was surprised that there was no gasket or metal washer around the fill or drain plugs on my mt. I'm also really surprised at how clean both the diff and MT fluids were after nearly six years (but only 15k miles). I used Fuchs Sintopoid 75w-90 in the diff and Pentosin FFL-3 which crosses per ZF to the right MTF for my gearbox. It's mainly a Porsche DCT fluid, but is an MTF per ZF. Shifts great. Despite the cleanliness of the fluids, I wouldn't mind getting a magnetic drain plug for the MT. Anyone know the plug spec?? |
