It's been a while since I've visited this site regularly... so maybe the methodology of changing fluid levels has evolved. In the past, you were supposed to jack the front and rear of the car up - so that the transmission and differential remained in their normal orientation, relative the ground. (Not tilted forwards or backwards) As far as I can see, you've created two videos, where you've only jacked the car at the front (gearbox fluid change) and at the rear (differential fluid change). Having the vehicle jacked up only at the front or rear, changes the way the fluid lays in the gearbox and differential - you're not draining it completely. Proper drain and fill was designed with the car's components being parallel to the floor - not tilted. Also, I've found that when my vehicle is supported by jack stands at all four corners - the sway bar isn't in the way - and I can successfully access the fill point on my differential.

I haven't seen the transmission video, but nothing wrong having the car jacked up only by the rear for the differential. It will drain completely as the drain bolt is on the front of the diff. It will be overfilled since the fill bolt is on the back, that's true. Overfilling a differential by that minimal amount won't hurt anything. The gears are splash lubricated and the diff is not vented. It is not all that sensitive to level.

I haven't watched the transmission video, but for a manual transmission the same goes. Splash lubricated, a little bit more fluid won't hurt. Automatic on the other hand, must be leveled to fill. They can be tricky if the oil level is too high.

Hi

So its ok to use Red Line GL-5 on the E46 differential? Red Line also has 75w 90 NS gear oil

Just want to be sure its fully compatible
