I'm absolutely no expert in this area, but maybe some of you are so it doesn't hurt to ask, right?

I have a 97 Tacoma with 3RZ-FE engine. I want to modify the transmission shift points so that it'll go into overdrive at a lower speed, say 45mph. Right now it will not shift into OD before 50mph, and that's annoying. Because around here most roads are 50mph and people often barely go the speed limit. I figure I'm losing serious fuel economy because I'm often stuck in a lower gear...I think

Anyone know how I'd go about reprogramming this sucker?
