Shifting Problems!!! - BMW Forum

jshearer · 01-09-2005, 03:56 PM

I bought my car ('94 325 is 5 speed) 4 months ago with 76k miles. At that time I had the tune-up done to it: changing oil, trans fluid(redline fluid), diff fluid(redline), belts checked, etc. After I got it back it was fine for a week or so then I noticed that every once in a while when I try to shift into second it wants to kick it out of gear and can grind too. It tends to do it more when it is cold, but it really seems random. I can doubleclutch it sometimes but even that doesn't always work. Most of the time now I have to go straight from 1st to 3rd, b/c I am worried about grinding. Does anyone have any clue what could be happening. I am not a car expert by any means. At first I thought well maybe the trans fluid I am using is too thick, or maybe the syncros are off.

HELP PLEASE!

That is the synchros. Replace the synchros in second and by replace I mean unless you are damn good pay someone to do it or just don't use second. Sorry there is not any good news for you, it pretty much sucks.

synchro problems are big bucks.. BMW wont even do it- they just replace the whole tranny

they had a service bulleting on their TIS software. This happens because of internal problems on the transmission, much likely the sincros.
depending how much they are asking to open the tranns and change sincros, you need special tools and high capacity press to get the gears out and change the parts..
so depending on the price for the rebiuld on the current tranny, look for a low mileage on ebay, or junk yard. ive seen 70k 5 speed tranns for around 500. this is what youll problaly will pay just on man hours..
think wise.

I got it checked out and they drove it and thought that the fluid I was using was too heavy a weight for the cold climates we have been having here. They changed out the fluid for a different lighter synthetic. Now it has not been too bad at all and is driving a lot better. Don't know if this is the real problem I will just have to wait and see, but it is a quick fix for now.

Also add that if your tranny mounts are shot this can also be contributing to the "kick back" of the shifter. UUC mounts are $35 and it looks fairly straight forward to replace..

i use a syntetic gear box oil, and yes it does help on cold weather the shifting is way smooth

bmw uses automatic transmission fluid even on the manual trannys, check bentley manual. but this oil greatly expads or contract with temperature, so in cold weather. the oil get way down there.

yeah keepusing the syntetic much better,.

also whenever possible check your tranny mounts, they bad farily easy, and replacement is an easy job,

and then also check how good are the shiter bushigns doing, are they worn out?
they are made out of nylon they wear out aesy, also there are rubber parts the give support to the shiter, change those too.,

hope it helps;.

Thanks guys I will definately check into the tranny mounts. Also victorgallas you are right about the auto trans fluid. It threw me at first because I was using redline manual trans fluid, and when they put in the new fluid the switched to redline ATF. I just did not think it would work the same, but it does.

Dude fuck all that shit...why even mess with ur Sinc...just go buy a short throw kit from AA or w/e company you choose...that shit wont kick outa gear thats for sure....not to menchen you'll shed off 35% throw on that 325.

Another thing...somtimes when i have my music loud...btw i drive a 96 328is...i put into second...and i swear its all the way in...cuz it clicked you know...WRONG...pops outa gear and i see the rev..."FUCK ME!"

make sure your shifts are prescise , other wise go with AA i think

used
um... I really do not think that the short shift kit has anything to do with the synchros... seeing how synchros match the rpm to the speed so that way you do not have to double clutch to down shift... The SSK simply makes the throw smaller for faster shifts and is only the shift lever... So yeah... I am not sure how that would help at all...
