it's only normal under HARD acceleration.....5 series w/ a 2.8 should shift driving normal around 2500-3000 rpm....it's a simple calebration to do.......it sounds like someone has uploaded a performance chip into your car....your dealer , or a good tuner shop can scan your 'putor and see whats going on.......and yes , many disadvantages........it's unduly stressing all the driveline internals for no reason........more use , quicker they weaken and deterioate. for your wallets sake , get your 'putor and shift points cheacked and set. A thought.....does your car have a "performance " mode switch??? if so , reset it to normal.

With an computerized transmission the RPM while it shifts relies upon on many products including throttle place, motor vehicle velocity, manifold vacuum, and engine load. The GM transmissions that end with the letter E are electronically shifted by using a working laptop or pc. I.E. the 4L60E transmission is a working laptop or pc controlled transmission. The engine layout itself will additionally make certain those shift factors. case in point. a greater extra effective engine could make its means at a decrease engine RPM so under popular using situations there is not any could desire to shift at a extra physically powerful RPM.there is not any set engine RPM while the transmission shifts. A 4 cylinder engine could carry the transmission in a equipment for an prolonged time because of the fact the engine demands extra RPM to make the comparable volume of means than a greater V6 or V8. For superb gasoline financial device you want it to shift as early as possible. try this by using using a easy touch on the throttle. additionally, maximum folk do no longer want a harsh moving computerized transmission. case in point. WIth my Impala, maximum circumstances the only way you realize the transmission has shifted is from the tachometer. The engine is quiet adequate which you do no longer pay attention the shift and the shift is delicate adequate which you do no longer sense the shift. the only time you sense the shift is that if on a 2 lane street you improve the throttle to the floor to bypass a vehicle. you sense the downshift and counting on the throttle place you may or won't sense the up shift. in case your transmission is moving at 4000 RM under easy throttle load you have a topic, probable an forthcoming transmission failure. Or in case you have in no way had the transmission serviced you have a blocked or in part blocked transmission fluid clear out. in case your transmission is moving at 4000 RPM given which you have a lead foot then possibly you may desire to regulate your using conduct. proceed to overcome the crap out of a 10 300 and sixty 5 days previous vehicle and assume issues to start up breaking.

The 528i isn't a m5, it's a 5 series. There was no m5 in 1997. Sounds like the trans. is messed up, or someone messed with the shift points.
What year is the M5 engine?

all modern cars are controlled by computers. that might be the shift point for that particular gear. it does sound high most cars shift at 3500-4000 unless in passing gear if the car is used you might want to take it to a mechanic or dealeership to see if the card has been tampered with and reflash the card to factory specs

Well if your not flooring it then no. But depends on the make. Higher performance will shift higher. Thats why standards can go faster, you pick the gears max speed.
I dont think its normal.
