torque converter

has anyone considered changing their torque converter?

I found one and was wondering if anyone has tried it or has any feed back or ideas

If you had an automatic with a centrifugal supercharger which made all hp/tq up top rpm this might help..... but if you have a klee blower with all that tq down low... I just don't see how this will help reduce 60' times..... you already will have traction problems and this will make it worse?

Has anyone actually tested this tq converter on a blown benz? Any documented time-slips before/after?

Raising stall rpm can add heat and not so good for daily driver..... is an aux trans cooler rec with this?

Hami - try it first.... and if you like it... I'll copy

I dont know of any one who has tried this thats y im not too sure about pulling the plug

I am just trying to figure out a way where my car would shift smoother
when driving regulary there is no jerling but when i tried red lining it it would shift funny

I was thinking of getting a tranny rebuild before I break it and see how that might help my shifting

other then that I am going to try every way possible to reduce heat soak

My car shifts perfect under all conditions, so I'd check the tune 1st. It does matter on these cars.

What's up guys! I trowed the blue top solenoids in the valvebody and it helped my shifting a lot. It shifts crispier and faster but not smoother. Also i'm not using the sport mode in the city for DD ing. the gears have harsh downshift, specially the 2-1 shift. In C mode it shifts much better that sport mode before the mod.

About that converter, it'm pretty sure it will give you a good .5 in the 1/4 just like it did with my truck. Had a stock stall of 1500 rpm and went with 3000 stall and gained .5. 60' time will reduced drastically only if you can put the power to the ground though.

It will most likely heat up the tranny so i'd check with Eurocharged if a tranny cooler is needed. I installed a big one on my truck and it kept the temp down. unfortunately we don't have a tranny temp guage so you won't be able to monitor it.

Say goodbye to fuel mileage with this haha!

The trans shifts funny at redline because it's making a pause. it's actually protecting your tranny this way. From what I've read so far. A tranny rebuild if way too expensive!!! try a tranny service coupled the noids you'll be very happy with this i'm sure.

I 'll look into the blue top it sounds like its working for u. I always keep the car on comfort mode and when ever im up for having fun i drive on manual but i rarely keep it on sport.

the only way to get it to grip is with a set of radials which I should be getting sometime soon but for now I am considering the torque converter if it comes with a cooling system heat soak is a nightmare and I need to deal with it.
im not very concerned about gas mileage my car runs an average of 33 mpgs on highway

yea I read that it does that to save the tranny I am seriously considering a tranny rebuild but if there is another option im going for it
i'll have more answers over the weekend

thx for the feed back

I would not put in a higher stall convertor for a daily driver.

A couple questions>>
* do these trans lock-up in OD (5th gear) only?
* or do they lock-up in other gears as well?

The reason I ask is if they don't lock up and you go to a higher stall you will be adding heat in every gear....... killing gas mlg, and adding heat all the time.... not soo good for cruising highway speeds.

If the car is a dedicated weekend toy, track car... not for highway... then go for it.

Very interested in what you find out, and your new track times.

I'm thinking your next week link will be rear axles.... if you run the high stall with big hp/tq and slicks..... I doubt the car will hook up with drag radials with 400-450 rwtq and the higher stall convertor.... but we'll see.

Hami is that a typo getting 33mpg on the highway?

How is that possible when my badass Ford Focus 1.8L gets maybe 35mpg highway and is even advertised as being great @35mpg...if mid 30's is worth advertising on a car a small as a focus what the hell is going on with yours? Impressive and confusing.

Per MB, they lock in 3rd, 4th, and 5th.

Marcus - as usual THE source for tech. Thx bud.

So high stall is all good for daily driver based on this...... because it locks up above 2nd.... so same as stock mlg in those gears.

In for explanation of 33mpg as well. I've hit 26.4 mpg max on the highway with one passenger, and no luggage. I had to cruise at 60 for a while to get that.

before I got the supercharger in it would max 21 maybe 22 mpgs
after that I noticed on long drives my mpg was hitting higher numbers so every long trip I took I would reset the the trip logs and take a picture of it when I get there

so back to the main topic at hand
well I am very worried about heat specially that I am shipping my car to the middle east soon and its very very hot there
the car wont be be my daily driver but I will be taking it on long drives on the highway and I dont want to risk any heat issues I already lost a car before because my engine was over heating but at the moment I am trying to figure a way to get rid of the pause between shifts while redlining before I take it back to the track

Wow! Could it be possible that this is some kind of error with the computer after all the mods? Can you compare by doing a fill up and calculating the mpg with the odometer reading? Betrezra have you noticed the improved mpg's after getting your car back too?

best mpg I have managed after mods is 22mpg (same as stock)..... that is at 60, or 65, or 70 didn't matter with ac on windows up and cruising about 2 miles each time.... just reading the computer.

And if I hammer it like a child.... it get's 14-15mpg

According to the MB press materials for the W203 C55, torque converter lock-up starts in 1st gear. Does the W209 CLK55 have an older transmission unit?

Sorry jack the thread up, no need for pics as I totally believe you just really surprised you get that milage. Hang on to that car then.

To keep on topic if anyone needs a TQ converter for a core charge or simply not to create down time of removing yours I have one if needed. Make offer if anyones intersted I'll let it go cheap. From 98' C43.

A tranny cooler is not hard to install. You just buy the biggest one you can find and it's cheap too. Just cut the lines of the tranny cooler ans install the new unit. About overheating, I'm very amazed at how the AMG 209 keeps the temp down and stable at about 85-90 no matter the outside temp. Make sure the tranny is never overheating at all time, not even one time.

You will then be ready for a new cam
