Bad Shifting

[iantosca]

I've been driving my automatic 328i and have lately noticed a decline in the shifting. I'm talking about the car shifting at much higher rpm's then it should be ... i know i have to replace my sparkplugs, but could sparkplugs really be the problem? also, should i just go with standard oem sparkplugs?

[jrhaile]

sparkplugs would not cause this... could be slippage in the tranny inself. Could be the tranny computer not working properly... I'd go pull codes.

Always get standard bosch plugs for your bimmer. other plugs in my opinion don't do shit...

Thank jrhaile and I will do that. Looks like I'm taking it to a garage on Monday, they can just change the oil and spark plugs while they look at it i guess. n

Hmm..Do that and let me know what it should be shifting at...my shift fine biut I would like to know if its stock.......

[iantosca]

Yup, no problem.

I had erratic shifting I thought was a major problem. Changed tranny fluid and all is well now. Hope yours comes out just as easy. Good Luck!

mine shifts at higher rpms, but this only happens the first or second time accelerating after turning on the car. Could this be the same problem?

If you stomp on it it will hold the gears a little longer for more acceration.

Try pushing the gas pedal gently (accelerate as slow as possible) and see if it still shifts at high rpms. When doing this it should shift up by the time it reaches around 2300 rpm.

If you stomp on it all the way it will go all the way.

if the tranny is cold it may take a bit longer for it to shift.

yea, i dont have an automatic, but when my moms car is cold it shifts a little late than it should

i just posted something similar, my buddy's car wont shift untill he gets to about 3,000 or a little bit over, and that's when he's goin easy on the pedal. but when he really presses it, it will go up 6,000 and it wont even be going fast. i think it could be the throttle cable. BTW, it's also a 318i auto.

318i auto.

theres ur answer for why it doesn't go fast.

lol

How many miles has it been since you changed ur tranny fluid? Have you/they done any moddifications like a racing chip?

lol... sorry i didn't mention this eariler but the car doesn't belong to me, it belongs to my friends. but he doesn't know crap about cars. i dont know when the last time he did anything it it was. but there is no preformance mods whatsoever it's all stock.
