Could you elaborate on/exlain the reasoning here more? Would you say the same for manuals?

 

If you were worried about seeing 200,000 miles on your Stang when you bought it. You should have went with the Honda Accord....[sm=icon_rofl.gif]

 

I think I found the problem with your car good sir.

 

He's absolutely correct. The reason is heat build up, which eventually causes damage to the transmission. The only reason that transmissions shift smoothly is for comfort, not for reliability. You actually want your automatic to shift as hard and as a quickly as possible.

It's no secret, though, people installing shift kits on older cars have been talking about the benefits for decades. Most consumers would find a hard shifting auto to be too rough, so we get lazy shift autos even in a Mustang GT.

As far as reliability, Ford is willing to sell the Shelby GT with an air intake and a Ford Racing tune as well as a factory warranty. If it caused significant engine problems down the road, then I don't think they'd do it.

American cars are built well nowadays. The warranties are also getting insane. GM offers a 5 year/100,000 mile transferable powertrain warrany and if you're really concerned, then Chrysler has a lifetime powertrain warranty. Ford used to offer a 5 year/100k transferable powertrain warranty on the Focus.

 

This is very interesting info.
Right now my shift pressure is +5% - +10%
So +25% is actually better for the transmission?

 

just wanted to chime in and say the 3.8 pontiacs (buick motor actually, even though they are *all* GM's) are some of the best motors to ever come outta the general motors camp.

+1 for the ford 300's kicking serious longevity ***

and ALL cars built nowadays will go 200,000 + if you take care of them. the only thing still sucking *** is FWD automatic transmissions (from pretty much all manufacturers) which tend to start puking closer to the 100,000-150,000 mark (they would probably last longer if people ever changed the tranny fluid on some sort of half regular basis)
