6speed!! AWESOME!!!

Moreira_C230

You are going to love the 6sp! The ratios are nice and tight and give your great control in pretty much any RPM band. I sometimes feel I need to shift very often to stay on the power, but given the extra liter you have on me with the 350, it will be much more enjoyable. Also I recommend starting in second if the temp ever drops below freezing. The tolerances from 1st to second are very tight, and until the tranny oil gets up to temp, 1st to 2nd is not all that pretty lol.

Enjoy her and let the modding begin!!

Ok thanks for the info! Im looking at doing a frount mounted single turbo. Just need a tuner that can work with me..

Can the 6MT handle that kind of extra power?

MBfinatic

I heard awhile back it could. This would be around 8psi at the start. I would most likely never go past 15psi if I built the motor. I know a company that was going to work with me to make a stronger clutch but if the tranny cant take it whats the point.

You have that too huh...the "ccchhhtunk" into second when it is freezing cold?...When I have to, I stay in first as long as I can to warm it up...In the morning, out of the garage - it is fine...Glad I am not alone...I hate that shift!

MTX is the only way to go when driving!

I didn't know I could get a W203 6MT when I bought mine. I wish I had.

Yea you are most definitely not alone. It was much worse before February of last year, that's when I changed the transmission fluid as well as changing the fluid level. After talking to my mechanic, he recommended placing in EXACTLY 1.2 quarts of fluid back into the transmission after a change. Since it is a manual transmission, the gears are only partially submerged and spin through the oil instead of being almost fully submerged like most autos (so not as much oil is needed). After changing the tranny and diff fluid, the 1st to 2nd shift was much better. It is by no means a smooth shift, but it is better than it was before. Changing the diff fluid also made more of an improvement than I thought it would.

Im going to do the fluids soon.

Anyone have information on the 6mt on the 350?

drtyjrzy

the first time I heard that noise shifting out of first I thought my tranny bolts were loose. very glad to hear that it's uhhhhh, normal? common? idk what the word is, while I don't think it's right, at least it's not a sign of upcoming disaster as I was fearing.

MBfinatic

Does no one have the info?

Moreira_C230

I think the manuals are the same. I believe I heard my mechanic say that, but I could be completely wrong. I think the powertrain is just about the same on both, with the differences being displacement and perhaps a few other things, again I am not positive.

I would like to think the tranny could hold the extra 68 hp increase from the 230 to the 350

MBfinatic

Karo posted a diagram awhile back showing that the 350 tranny was bigger and stronger somehow. I cant find the thread though .

MBfinatic

How many miles are on yours?

vdemon311

changing my 6mt tranny fluid to Redline MTL helped the 1st to 2nd cold-clunk shifts A LOT.

MBfinatic

Does it take a special fluid?

Moreira_C230

I just topped 69K miles. As for the fluid, I used the factory fluid supplied by Mercedes. I know redline makes a suitable oil as well, but I didn't feel like waiting for shipment lol.

MBfinatic

Well im about to do some service before the mods so that is deff on the list. How much fluid does the 350 6mt take?

6speedclk

My 6mt behind my V8 seems to be holding up pretty well. I want to know if they make
A single mass flywheel. And a shifter withe a little less slop.

MBfinatic

You have a clk500 with a 6mt!?

MBfinatic

Just added ultra high performance K&N filters. Now its time for some new wheels.

6speedclk

I did a full conversion with parts from a 01 C240. I made the c240 an automatic and drive it daily.

MBfinatic

You should pm me details. I wish I knew about this when I had the C55 amg. That M113 so could have used a 6MT.

MBfinatic

I got a oil leak near were the tranny and the engine meet. Ughh
