So, the upshift (keeps it in 2nd until it warms up a bit) delay on my 300E is annoying, I just realized while under it today that there is a nifty little tube that comes out of the tranny, into a solenoid, then back into the trans. It has a cable plugged into it.....so....if I unplug this, no more upshift delay, but will it make the car computer angry? I already have a permenant check engine light/code 12 since I disabled the EGR on the car, but will unplugging it cause any other issues aside from an extra code? It'd be nice to have it drive without the emissions nanny....
