hard shifting to 2nd gear

On my 4.01, I noticed it is hard to shift 1st->2nd gear after a cold start or idiling at traffic light. It had flywheel replaced as due to a recall. Is it an expected "feature" of tranny?

thx

my 2001 vert had this problem. the tranny was rubbery and fought getting into 2nd consistently. i was told by multiple stealerships that the tranny was "normal" and that's "just the way it was designed." I bought the car CPO with 3k miles on it, put 20k on it myself in one year, and it never went away. The transmission was the only thing i didn't like about the car. I decided to get SMG this time around and have been very pleased with the matching of the tranny/s54 so far.

try some Royal Purple MTL. Many times it will help a manual gearbox, not transaxle, shift better expecially when cold. If that does not work take it to the dealer. It could be something as simple as cable/linkeage adjustment. BTW, it only takes a couple of bad shifts to toast the bronze synchros. The trans should shift smoothly.

mine is past 38k milestone. It feels like there is resistaning force working against. No grinds noises or anything. If I let it sit in neutral for a sec it goes in more smoothly. It mostly happens right after cold start or a long idiling time at the traffic light. So is there something wrong or it is a "feature".

It's not a feature and don't let anybody try to convince you it is. BMW boxes are not the smoothest but on a 1-10 scale I would rate them an 8. You shouldn't be "feeling" anything between shifts and gear engagement should always be easy when warm.

That your car has 38K and it does it when it's warm bothers me. Could be a worn synchro. Could be lube. The lube is a more complex mix of friction modifiers and additives than you would think. Too slippery and the synchros don't catch for example. Many times there are load additives that break down as well.

The first thing I would do is to change the oil myself. There is a good DIY on it. The key thing is to look at the magnetic drain plug when you pull it. If it is clean a lube change will no doubt help. If it has lots of filings on it it's bad juju. If the oil smells like rotton eggs (sulpher adds. that break down when hot) you're overdue. Make sure you can get the fill plug out before you drain it.

FWIW, I change the gear oil every 4 hours in cars I track and it always needs it. There is a huge differance in lube life in a "normal" street car and one that is driven hard.

The bad news is that if it is a synchro it's pricey. Very round numbers figure $800-1000 labor plus parts and the parts are very expensive.

savyer,

It is a "feature" of the BMW manual. IMO, it also seems as BMW is trying to force everyone to SMG. You can run Redline, Royal Purple, whatever you want; you'll still have a little fight with the 1-2 shift while it's cold (and to some extent when it's warm).

I'm running Royal Purple and it didn't help that much. My car has 34k on it (bought it at a little over 10k) and it's been the same the whole time. It's really interesting if you live in a area with winters.
