ive found from 2 to 3rd wen around 4700 as thats the best time, shift the stick up, drop throttle then hit it again really fast, it allows it to shift then engage safely with out damage, and ulll find u wont loose any speed, if u use it like a manual, shift like a manual, wen manuals shift u hit the clutch and release throttle then drop clutch and hit throttle again...
so if ur consisting on driving like a manual drop ur throttle,
and to u purple monkey, autos arnt meant to be used like a manual, other wise u would only have manuals, first on the auto is used f or hard hill climbs or towing, along with second, thats wat its there for and not for manual users. so im sorry but garth is right.
so just treat ur auto easy, well wen i say easy, i mean back off to change, it will only take a split second, that way u will get 10 or 20 or 30 years from ur auto and not 5
