BMW 5 Series
I just bought my first BMW 528i 1997. I really love the way the car drives.
I am concerned about the automatic transmission though. When the car first started in
cold weather, I typically drive with caution and keep a light touch on the gas.
1st and 2nd gear seem to shift around 2K RPMs but when it comes time to go from
3rd to D it won't shift until the RPM have reached about 3500. This seems really high
Even if I let off the gas doing 35 MPH it will not shift into the higher gears.
Is this a feature or a problem? WHen the car warms up the shifting still seems hard
from 3rd to D but not at low speeds. I think the car is still under factory warranty.
It's in service date in 6/97 and is has 35K miles.
Has anyone had a similar experience with their car and what did you do?
Regards,
tom

Take it to a dealer and have 'em take a look at it.
btw, the 5 spd automatics used on the 5 series(V8 5 series), 7 series are ZF's.
the 4 spd autos used on the 3series (328,330,325, etc) are general motors' ones.
if your service advisor knows this, he is a better trained one so ask around.

Bellhousings differ to suit engine applications.
Warranty is 4 year/80,000 Km, and if transmission operational irregularities are perceived, there are numerous programming updates.
about the clutch on the 540i 6-speed. I've had
50 years of experience with very good clutch life, including four previous BMWs. But my 540i 6-speed clutch lasts only about 40,000 miles before it starts slipping badly. I'm about to replace the clutch for the second time at 88,000 miles and I know I have not been abusing it. My last BMW clutch had 105,000 miles on it when I turned it over to a son. He had no problems for the next 85,000 miles.
