I need a little advise, I am the currant owner of a 02 SLK320 and am looking into purchasing a SRT6. The trans in my car is
well just plan awful, long sloooow shifts even at WOT, harsh downshifts that upsets the cars balance, in manual mode you need to
lead the shift by at least 1000rpm to avoid hitting the rev limiter.

I did some research into the trans and am surprised at what cars it came in, this is a beast of a trans! Very strong. I see that the
SLK 32 AMG came with a faster shifting version of this trans and I'm sure that the Hellcat shifts faster then this.

The question is does the stock SRT6 shift quickly or is it as bad as my car. Is there mods that can be done to make the trans
shift faster-harder?

While on the driveline subject, is the rear strong in these and do I have a few final drives available?

Thanks! Steve
