Manual Transmission

Where do I add the fluid for a 1988 BMW 325I Manual Transmission?

by admin on December 13, 2009

My clutch was working great and then brake fluid light came on, I rode for a few days (not far) but when I got in this morning the clutch went to the floor. Has no pressure, I am not sure if there is air in the line but I dont know where to add the fluid? PLEASE HELP!

The clutch and the brakes share the same fluid. If you have no pressure with your clutch, then your brakes won’t have any as well or will not have any after a few more pumps. You should take this one into the shop.

Why does my manual transmission BMW use ATF?

by admin on December 13, 2009

BY what i know ATF stands for Automatic transmission fluid so if I have a manual why does the car need it?
PS Im only 18 and am just starting to get to know cars

18 years of age is not a bad start. And I think you are on the right track for being interested in things like cars. Unlike some people who are much older who do not even know how to open the hood, much less how to add coolant or oil or add air to the tires.
But do not think that all BMW manual transmissions use ATF since they do not. Even BMW automatic transmissions do not all use ATF.
Why BMW uses and recommends different kinds of oils is a complex question which lesser mortals like us should not bother with. Forget about the why. Just use what is indicated on the label under the transmission, or what is officially recommended as per TIS or EPC
(BMW repair procedures and parts catalog). Sometimes comparable oils can be bought outside of BMW and naturally they are cheaper.
And you should have mentioned the year and series of your BMW for a more rational discussion of the subject as it relates to your car.

Should I get a BMW with manual or automatic transmission?

by admin on December 13, 2009

I’m thinking about getting a used BMW..most likely a 3series from the low to mid 90’s. I feel like it’s a disrespect to a BMW if I get it in automatic trans, but does the transmission make the car that much different?

Both are the same for dependability.

SERIOUS EXPERIENCED ANSWERS PLEASE: Does the Dual Clutch Transmission (DCT) of BMW have a clutch pedal?

by admin on December 13, 2009

An ordinary manual transmission car has 3 pedals: gas, brake, and clutch. How about the DCT? Does the DCT only have gas and brake? Does it have paddle shifters? Please answer all questions and how do you drive it? Is the procedure just like the SMG in the BMW M5 and M6?

From a driving perspective yes it’s the same as the M5 and M6 with SMG as there is no clutch pedal. The biggest difference is the uninterupted flow of power.
The M DCT with Drivelogic combines two gearbox
components in one common housing with the same compact dimensions as a conventional manual gearbox. The “heart” of the new M double-clutch transmission in technical terms is formed by the two oil-cooled wet clutches.
One of the two clutches is for the even (2, 4, 6), the other for the uneven (1, 3, 5, 7) gears and, in addition, for the reverse gear. While driving, one of the two clutches is always closed, the other is open.
When accelerating – and when shifting down – the clutches are activated in an alternating process, one after the other. When shifting gears, the first clutch opens just as the second clutch is closing. This ensures an absolutely smooth and comfortable and at the same time an incomparably
fast gearshift without the slightest interruption in the flow of power.
This interaction of two clutches ensures a super fast rate of gear change in particular because the transmission control unit pre-selects the next gear with the transmission ratio matched ideally to engine and road speed and keeps this
gear waiting for immediate operation.
So when you’re accelerating, say, in third gear, an immediate flow of power is ensured by the appropriate clutch and the gearbox component controlling the uneven gears.
While all this is happening, the gearbox segment responsible for the even gears shifts to the gear required, in this case to fourth gear. The only operation required for this purpose is to close the clutch for fourth gear, at the same time opening the clutch for third gear, the power of the engine then being transmitted through the new gear with its different ratio to the wheels.
This entire process takes only a few milliseconds, meaning that in the time a skilled driver takes to press down the clutch pedal the DCT has easily completed the entire process of shifting gears, continuing to accelerate in the next gear higher up.
There are also 11 programs of driving styles ranging from auto comfort to super sport.

Oh – and of course launch control! Houston – we have lift off…. :)

Anybody ever use their Streptronic transmission in their BMW?

by admin on December 13, 2009

I just purchased an ‘04 BMW X5 with Steptronic. I am a former manual transmission driver but have found the "shifting" of the steptronic rather odd. I keep wanting to reach for the clutch but of course there isn’t one and cannot get the transmission to shift smoothly regardless. How exactly do you do it!? I do think it is neat and I am sure it will be more fuel efficient I am just new to it. Any pointers or tips?

i too went from a manual car into a BMW w/ Steptronic..

i release the gas pedal between shift points… but i mainly use it to down shift… it works great when your on the highway and traffic comes to a rapid stop

overall you’ll just gotta practice w/ it. Its not going to feel like a real manual tranny.. but it not too bad
