But they shipped more X-fire's here, and probably a bunch more than that were MB cars...

I think it had to do more with DCX's hating of manual transmissions and warranty work than anything else. Look at what they did to the SRT4 guys, they put out a specific book on mods done to the cars and what to look for, to their service techs.

I think the rear end is the weak link here. Probably were afraid of endless warranty claims from blown diffs from high RPM clutch-drops. That and clutch assembly replacements. The combination of big rear tires and high torque/Hp in a sports car at the dragstrip with a sticky launch pad equals lots of broken parts. I've seen Vipers at the strip several times and they all seem to either have or are on the way to a toasted clutch ! Sports cars with manual trannys and high traction drag strips are a bad mix for dealer service departments...

The 6 speed manual was not durable enough for prolonged use on the supercharged M112 engine, hence AMG opted to utilize the bullet-proof 5 speed automatic transmission instead. A little factoid: The SLK32/SRT-6 shares the same exact transmission with the SLR.

Nice... I would not have guessed that one.

This all of course begs the question: Is there an off the shelf Mercedes manual transmission with the correct hole pattern, mounting locations, OAL & compatibility to work with an SRT-6?

What would such a swap entail?

Would you need to also get your hands on a new ECU to work with a manual, or is the transmission's controller separate from the motor's?

(I spoke too soon before having ruled myself out of the SRT-6 chase. This thread has me thinking it might be worth contacting a dismantler/recycler in the UK).

Well, its a beefed up version, not the exact one. it wouldn't last a day if you swapped your tranny with that in an SLR... but it would bolt-over.

----------

SLR TRANSMISSION
The Mercedes-Benz five-speed automatic transmission and rear final-drive unit, already used successfully in several high-performance models, have been further modified to handle the high torque of the SLR engine.

In addition to beefing up the gear housings and torque converter, gears in the center and rear planetary sets have been widened by five millimeters (about 0.2 inches), and the front planetary gears are two millimeters wider. While the wider gear teeth are stronger, this also makes room for larger bearings. What’s more, the hydraulic clutches that drive and lock the planetary sets in each gear range operate at higher pressures.

The transmission oil cooler is larger than on other Mercedes-Benz high-performance models, and a separate oil cooler just for the rear differential/final drive unit is mounted under the trunk floor. Air flows through this cooler from a triangular NACA duct in the otherwise flat underside of the car and exits through a grill between the back-up lights.



A New Level of SpeedShift
The Mercedes-AMG Speedshift system offers even more features in the new SLR. A **** on the left side of the center console offers a choice of three settings: “Comfort,” “Sport” or “Manual,” and each setting is identified in the instrument cluster display by the letter “C,” “S” or “M.” While the two automatic shift programs are similar, “Sport” provides higher-rpm shift points and crisper shifts.

In the “Manual” setting, the driver can shift either with buttons on the steering wheel or by using the side-to-side Touchshift feature on the shift lever. Within the “Manual” setting, another **** on the right side of the console can select any one of three modes of progressively sportier shifting:

Stage I – “Sport”
Stage II – “SuperSport”
Stage III – “Race”
In the sequence shown here, the shift response and transmission shifting speed become increasingly shorter.

Just installing the mechanicals would be a chore... Can you imagine building a clutch assembly into your floorboard ? Talk about a "MONSTER GARAGE" project...

See the attached photos of Mopar's Crossfire drifter.

The first photo highlights the Renntech link to the 400HP SRT-6 engine.

The second photo highlights the fact that the car is a manual.

The third photo highlights the possibility that the actual car is a base or limited model (note speedo MPH).

If only Chsryler's Skunkworks would reveal some of their secrets and that body kit!

There were no secrets, it was "ALL SHOW AND NO GO" for SEMA a few years ago...

Not jaded at all... Fact is fact... I spoke with these people, I met with these people... I had hours of discussions with the guy who ran the Crossfire program, I had hours of discussions with aftermarket vendors... If you have a problem with the truth, don't take it out on me...

If you don't believe me, then I would suggest you contact the head of Crossfire Operations for the former DCX and let him tell you directly... They could not even get engine specs for the car from MB until I started rattling cages to get classification for SCCA in 2005... If you doubt this as well... Contact the current president of SCCA, Jim Julow, who happens to be a former DCX executive...

I was simply stating the FACT that the car has a manual transmission, presumably the 6 speed from the limited, and the FACT that it was mated to the SRT-6 engine.
