I seemed to have run into a "strange" behavior in the SS. I don't have any tranny problems, but I was shifting a bit slow while my attention shifted and noticed something that made me wonder.

On some occasions when shifting with the SS, when I HELD the SS up or down (as opposed to just "popping it up or down") it seems to have caused 2nd to 3rd and 3rd to 2nd delays(actually I’m still trying to find a good way of explaining the behavior). I don't want to try this again-and-again for fear of screwing up the tranny, but I have a feeling the ECU can get a bit lazy at times.

I'm wondering if anyone has ever held the SS up or down during a shift and noticed a change in shift operation?

My normal "computer mode" thinking would have me think that there may be some "code" in the PCM (Powertrain Control Module) part of the ECU (PGM-F1) that is "funny" and could allow for a slow or sloppy SS shift to cause excess wear on the clutch packs. I would normally expect an upshift or downshift to be interpreted as a "pulse"/"event" that would NOT change the shift transition time based on how long the user held the lever up or down.

Thoughts?

Ever noticed this?

 

Never noticed this.

I use SS all the time and about 1% of the time, I push and hold just a little long.

No difference.

 

It was always erratice. Sometimes it would shift right away with little touch and then other times you had to do it a couple of times with some force.

 

If you ever get a chance, try holding it up for a second or two...

I was caught off guard, so I had never done this before and it doesn't always replicate. It's subtle... at least for me.

 

just tried it. shift speed was the same both ways.

sometimes that 3-2 shift just doesn't feel that good


i had a situation the other day when the tranny would not shift 2-3 at redline. i tried 3 or 4 times then clicked over to auto. it worked fine later. seems cpu related

 

depending on how heavy on the throttle i am, i'll get a lil lag, but it's marginal...usually, when i'm "lazy" shifting in SS, i'm not aggressive at all on the throttle, and i'll get the lag

 

you do have a tranny problem, take her to the dealer, dont end up like that Amir guy in a huge accident

 

I just tried my SS, I noticed that there is a slight lack in the beginning shortly after I starts the car, but after I drive around for a bit, the lack seems to go away.

 

I have had the same problem. Fortunately it isn't when I am racing someone but it is frustrating and a bit scary.
