E82 135i N55 - improving the gearbox

Post by mikeyscott » Fri Mar 16, 2018 9:14 pm

Apart from the CDV (yet to do), what’s best ways to improve the manual gearbox. Notching and not great IMHO.

Want to sort it out along with a few service items etc. Probably advertise the car in the next 3 months.

If you have yet to do the CDV, you should.

Have you changed the oil? My gear change improved quite a bit with fresh gear oil...after a few miles.

CDV mod, new fluid, Storm Moterwerks gear knob and some E46 M3 transmission mounts have transformed the change in my gearbox.

Yeah, think I got mine from my local BMW parts department a while ago but Cotswold would probably be able to supply cheaper. IIRC they weren't that expensive for an OEM part.

I changed all of the above stuff at the same time so I couldn't comment which made the biggest difference but I did notice it felt like a completely different gearbox on the test drive.

I’ll get a quote from parts and then Ergen / Iridium to do the work.

Only done 200 miles in the last 4-6 weeks, so car on borrowed time, but to upgrade to what without spending £20k etc. Spend £1k+ to shift it on in 3 months etc lol
That would be M3 arms, inserts, CDV etc plus service and rear tyres

Daily I prefer my Volvo, but then it has cruise, comfortable and I get left alone

I very rarely get any in mine. It's debadged so unless you know what you're looking for it just looks like a standard 1 series diesel and that suits me.
The look on some people's faces when they have tried it on have been a bit comical :lol:

Aha 'Chall5'...was it you?

Likewise, I had no badges, consequently I don't think many suspected that my car was quick. Contenders were a late quick Astra that took me a while to dispatch, a V8 M3 who tried very hard but didn't get in front of me on one of my favourite roads, a 2.3litre Elise (friend) who couldn't get away from me (oops - that would make me the challenger!) and a Monaro that I just couldn't shake off.

What benefit do the m3 mounts give?

They are slightly stiffer than the standard mounts from what I could deduce on t' internet. I didn't notice any more NVH after fitting them either. Maybe on their own they don't make much of a difference but the standard mounts they replaced felt a bit softer and had more give in them.

I replaced a few bits all at the same time so couldn't give anyone any definite answer regarding how much of a difference the mounts alone make.

I have cdv delete, bmwp short shift, storm knob which all made a difference but nowhere as much as changing the gearbox oil. I won’t call it silky smooth my my lord, what a transformation. It’s only knotchy into 2nd when cold now and that passes after a few miles.
