OK- Call me stupid- but if you are not supposed to manually shift a stock trans, why would the factory equip so many with Slap-Stik's etc? Luci- you have some splainin to do-



It's called an automatic transmission for a reason and it's intended to be used that way. It's not that you're never supposed to manual shift it's that you're not supposed to make a habit of it.

For one reason, obviously you'll wear out the shift linkage sooner.

For another reason, when manually shifting from 1-2 the rear band is applied and must release at each upshift; the rear band was never intended to be applied/released at each shift cycle and the release is so slow that it wears much more than it would if only used occasionally. The rear band isn't applied when in 1st gear in Drive.

Also, when slowing down to stop in Drive, the trans will downshift directly from 3rd to 1st, bypassing 2nd. If the trans is manually downshifted to 2nd often, the band will wear out sooner due to the added use drum direction issues.

Leaving it in Drive will eventually result in less wear and tear.
