Shifting My Auto

[Slvr e39]

I know it sounds weird but hey, auto gets very boring! So I downshift and rev match to slow down and on occation will shift up to get as much power as I want without the computer deciding when that is. Is this bad for my car/transmission? I really dont want to be messing up anything...

Everything in moderation... What you're doing "shouldn't" do any harm or damage to the engine/tranny. I do the same thing myself, especially in city traffic, or in highway congestion, when i want to slow a little without using brakes. Just be careful when going back to drive from sport...dont drop into neutral...especially on the highway. Switching back to drive from neutral at a high rpm can cause damage from the increased stress.

Thanks for the info...

My car doesn't let me go from neutral to a gear without my foot on the brake, I could do it if I wanted, but no on accident...

check the following;
In Europe an acceleration-assist feature is programmed in to automate a 4000-rpm clutch-drop, clutch-slip launch, but an internal counter permits only one such launch per hour, 30 for the life of the clutch. We won't get that, so for best results engage S6, floor the throttle to call for an aggressive clutch drop, then back off to 75 percent to allow the tires to hook up at about 3000 rpm. Then keep your foot down, upshifting at 8000 rpm.
Enjoy

Kinda hard to understand, first off, what is s6?

I think he is talking about the SMG Launch Assist...

which the 98 528i doesn't have...

Lol, I have an smg m3, I should have guessed but I thought that was pertaining to my car or just fully auto in general, not sequential or even tip tronic

You can go from neutral to drive without your foot on the brake, all cars let you do that. You cant; however, go from Park to Drive without your foot on the brake on newer models.

Anyway... In theory It should harm anything, buit an auto tranny never likes to not be in control and shift up or down at high RPMs too often. The safest way I'd say is to use your kickdown button (not too great too often either. lol)
