it will throw an SES. let the tranny warm up and then try driving under light throttle - it really bangs into 2nd gear. But the only way to avoid throwing the SES is to leave it plugged in, or maybe wire in a switch so you can "turn on" the hard shifting temorariliy. I only get codes when I start my car for a 2nd time, so maybe if you make sure everything is plugged in before you shut the car down, you'll avoid the code

 

I have an 03 SE and STILL cant find the damn connector. Does anybody know with an 03 know which connector is???? Also WE NEED A WRITE UP ON THE SWITCH PLEASE.

 

After unplugging the drop resistor and driving the car (shifts were great!) for about 10 minutes I concluded that I wan't this option. Plugged the resistor back in before starting engine this morning and noticed the O/D light flashing for about 10 secs and then turn off, and no SES light!. This evening I again tried disconnecting the drop resistor and taking it out on the highway, shifts were a little faster, expecially 1-2, other thing I noticed is the SES light came on! Will it go off after a few days or do I have to do an ECU reset!? That damn light is very distracting!

u will have to reset the ecu... don't think it will go away on its own... some how i have managed not to get SES light... i have unpluged it 4 times now and ran the car for anywhere from 10 min to 1 hour each time..... i guess i'm lucky...
