you guys are still beating a dead horse! contact autotech in cali. they can build you a lsd for under 1100 that bolts in and uses the same ring and pinion you have now. zero issues and can withstand 1000 hp launches.
btw drexler wont touch a custom diff for under 6000$!!!

Drexler quoted me $2000.... I posted the email a little while ago. I'll see if I can find it again and post it here.

120k miles frequent tranny fluid chgs and not ONE tranny failure especially with the bigger torquier 5.5L motor in place.

DRBC43AMG

Well that's a real compliment for a supposedly weak tranny and a sure recommendation on how to avoid possible failures

503C43 ////AMG

Yup.... A regular maintenance schedule with the tranny and you should be good

C43AMG

Don't bet on it.I'll bet right now I had the most amount of "flushes" of anyone on this board with these cars.6 tranny services in 27k miles (5 years of ownership - bought car with 53k on it ) and the tranny still ***** the bed this summer.I "replaced" it with a brandy-new one...not rebuilt.Everything about ProjectC55's car is abnormal....its just freak !

LawRens

You probably just got lucky with a good w202. Check the majority of the c43 owners; the transmissions betrayed them. And just wait til you get to the higher mileage. Mine failed at 138k, i wouldnt be surprised to see yours go out anytime in the near future either. When these go out, they don't give warning. One day of driving during mid-failure, tops.

ProjectC55

138k is understandable for a re-haul. However with mine, so far so good. Alot of hard driving with the 5.5L motor. Speedybenz autocrosses his on the track with frequent oil chgs and he's still good to go. Amsoil all the way and he says so far so good.

First failure,I will keep everyone posted.

austinholloman

See post #40 for the LSD that WILL work and not cause ANY issues with the ESP or ABS or Tranny. Works just like the stock rear end but no one wheel tire fire!

austinholloman

Hey what Amsoil are you using and how often are you flushing. My was down about 20k miles ago and I am thinking I want it done again before 30k miles. Are you also changing the rear diff fluid at the same time or does that fluid last longer?

LawRens

I do pray that this doesnt happen. Somehow there are those few 722.631's that were built perfectly and may never experience failure, and you just might have one of them. And waiting for your car to come out of the shop repaired feels like an eternity.

Saaboteur

Looks like that Wavtrac may work with the C43? And the SLK32/Crossfire guys have done all the hard work already?

Yeah this is coming from 320 Dreamer who seems to be in the know. Pretty sure this is what he is running and last time I heard he is in the 11-12 second 1/4 mile range so the LSD has got to be able to withstand some power.

eundaddy

you have to remember that hp/tq numbers dont always dictate whether one car is faster than another. also, i remember reading an article somewhere that the 335i's hp figures are understated to keep the insurance costs down for the prospective owners.

320 dreamer

my mid 12's were without the wavetrac. it is in building stage and we should have the first test unit in early jan. its going into a crossfire with a sl55 s/c 5,5 v8. if that doesnt break it nothing will!!

btw the 12.6 was with a c3 pulley no tune and dr's in 90* heat. should be in low 12 high 11 range with new intakes retune and better dr's!

503C43 ////AMG

I think the numbers were played down due to the fact that they were close to the M3's numbers and why would anyone want to buy an M3 for an extra $30k+ when you could get a 335i for much cheaper and have close to the same power....

503C43 ////AMG

NICE!!! Keep us posted on the LSD...

ejrchef

Quaife also makes a helical LSD specifically for the c43. Anyone ever known of a c43 with a quaife LSD?

DRBC43AMG

Wow thread revival and yes they exist with the Quaife in the UK

you can get a factory limited slip differential that is made right for your car. just have to talk to your parts guys, take the filter off and then the part number pops up, if i remember right it's around $800 my cost. i don't think a lsd is really needed for c43. i might do one for my c43 5.4, still i don't think it's very necessary.
i don't pound on it from a stop all that often though either. not really what the car is all about to me.

and for those on the first page yelling and screaming about lower geared differentials and sourcing all these wild things. the c230k diff was something like 3.46:1, it would bolt right in and would be a very nice boost off the line and through the gears, all you'd ever want I think. The problem is then getting your transmission module coded for the new gear ratio. I don't know how you'd go about doing that.
at 80mph these things are singing at 3,000 rpm anyway stock. I wouldn't want much more than that, but that's me.

and they didn't have the n/a 5.4 in 98, at least in the states. it arrived in the 99 model year.

Quaife LSD for C43 AMG is sold on UK Ebay.
Hefty pricetag on that part!

benzslo

Exactly what **** the bed on your transmission that required a replacement?

Everything is serviceable, no reason to replace due to one part. I'm guessing whoever was working on it simply wasn't familiar with it and just went with the shotgun a new trans at it approach.

I do all of the transmission work at my dealer. I do not remember the last time I have completely replaced any 722.6 transmission, if ever.

There is entirely way too much false information on this site about transmissions, and many other things.

95% of transmission repairs on these are the conductor plate. Certainly no reason to replace, unless you don't know any better.

335i has a turbo?

nd4spd13

Yep. Twin turbo up to like 2010 I think, and single turbo after that
