05 GT auto tranny in 3rd slips??

[sswapp]

When I am in 3 at take off, it revs up a bit- then has sort of a hesitated slip feel to it. I drive around in D in town- but is this normal? Doesn't matter if Traction control is on or off. Any ideas?

Wouldn't recommend starting from a dead stop in 3rd unless your on glare ice. You can shift it manually starting in 1st & shift as needed.

It's probably just the torque converter at work.

Thats normal if your going to get on it try leaving it in drive and just turn the OD off, works for me.

Yeah, when in town I either manually shift - 1,2,3 or D with O/D off. What you are feeling is the converter slipping, it's not hurting anything. Solution - Don't start in 3.

What's different about the Stang's auto trans from any other trans I have owened before, is that 3 is just 3, not 1 through 3. Trying to start in 3 is like trying to start a manual in 3rd. I suspect that you are used to cars that shift 1 trough 3rd, when in 3rd. Not sure why ford did this, but don't start out in 3rd. Best, L.L.

They did it because they wanted to give us Auto fans all 5 selectable gears, good job Ford.

So its like a manual valvebody?

 

[Mr_Q]

They could have given us 5 selectable gears AND still let the electronic tranny downshift from the selected gear when needed.

IN FACT some of the tuners out there are trying to find a way to force this via a tune. But so far it doesn't look good.

I'd LOVE to be able to leave it in 2nd or even 3rd when doing the weekend autoX. As long as it downshifted.

The 5R55S shifts into 3rd and 4th synchronously (basically like shifting into OD in the 4R70W, BAD JUJU when you add too much power).

Yup, I am definitely getting on the phone with Emerald and TCI to see what rear gear and TC will be the best for long life with a supercharger and not fastest time down the strip.
