silly, you hit another great trick that i do.....coasting in neutral with an auto. I do it ALL the time, we have not a lot of hills, but enough. And once your exit ramp comes up just pop it in neutral and coast the whole way........... and you can put it back in drive ANY time you want, you wont hurt anything at all. As a matter of fact, i used to shut off my old car on this one hill(it was a manual), and coast the whole way, then when i slowed enough, i just put it in gear, release the clutch,and seamlessly keep moving.. lol
Someone asked about the TCC conversion, that was my write up. Maybe do a fresh thread on it?....
