blue top solenoids in trans
so been researching how to get the cars shifts feeling better and faster in my 03 sl55 and after searching it looks like the slr/blue top solenoids are the fix.
it looks like it depends on the year of your car as some may already have them. has anyone done this in their sl55 and does anyone know if there is production or year cut offs to ones that already have them?
from the e55 side it seems anything pre 2006 maybe 2005 did not have them. anyone know if this holds true for the sl55?
i found them on parts.com for $165 each, which looks like a good price.

Go into your das and investigate/ study the adjustable tranny shifting parameters. There are many of them. There are even more in the developers edition (how good is your German?)
I don't think there is any need to upgrade solenoid hardware. Your money are better spent on a tcu tune.

money already spent on tcu tune. didn't notice much over stock. definately not enough to change the way the trans over thinks all of it's shifts. a tcu tune from one tuner is slr parameters. the only other change from the way an slr shifts is, yes, the hardware. solenoids. the trans is the same.
the diameter of the opening of the solenoids will change the pressures induced to each clutch pack in the trans. i personally am sick of a trans in a "performance car" that takes over one second to change gears. when making more power you have to shift earlier, and lose time over the shift. the faster the shift, the more you will stay in the powerband. last time driving my car i would have to initiate shift at 4500 to not hit rev limiter. that is crap imo.
trying to find a better way. if there was a 6 spd manu version of our cars i would do it in a blink!!

My car gets rubber sifting from first into second sometimes, never touched the trans. Before I did my cooling upgrades, the only time shifts seemed laborious was when the car got heat soaked. Some say the TCU tune = placebo effect.
Edit...You can open your hood, look at the engine while you power brake the car to see how much your motor shifts. It the engine looks like it wants to jump out of the engine bay, you may need motor/trans mount.

i posted a great design for mounts earlier. just follow that. it still will allow slip at very high loads and allow variations for install. the trans mount is easy.

i think you guys will be playing with fire.
those things (the trannies) are really tuned to work well with stock valves.
you can certainly replace the valves, but i am thinking software adjustments will be needed also as everything pressure-wise will change.
btw, parts.com have the big valves for $164.40

i also heard (don't quote me as of yet) that the v12tt cars and the black series also had the blue tops. that is where the part number comes from.
it's not playing with fire at all. they just saved the good stuff for the higher end models. same as every other manufacturer.

unless someone can chime in that knows for the sl chassis, i would put a guess that it ran the same as the e55's. so 2005 and earlier would be brown tops. i will be pulling my trans pan soon to take a peak, which sounds like is the only true way of knowing.

i am sure i can sell them quick if i need to. it is my understanding only the sl65's and the slr's had them.
if it is true and mine already has the blue tops, it seems there is no hope for this trans. the thing i hate most about the car is the shifting. if mine has the blue tops, i think you would have to shift off idle to get a gear change at redline with the brown tops!
after all the body kit and all other recent mods this was the one i was most excited about. i need to hit jerry up for a way more aggressive tcu program then.
