2 to 3 shift 2003 Santa Fe 3.5L V6
Anyone notice a "stutter" in the 2 to 3 shift in their 2003 Santa Fe with
3.5L V6 ? I have taken it back to the dealer who tried to "flash" the chip
that controls the transmission but this didn't change it at all. They said
they notice that there is a distinct hesitation, or "stutter"as it shifts
from 2 to 3. I would describe it as a very lazy shift that almost seems
like it slips before it grabs 3rd.
I am looking for suggestions as to how this can be fixed if anyone has the
experience.
Thanks.
Mick

There is a TSB fix to reprogram the bump. And you don't even have to take it
in to the dealer! Try this..

There is a possible fix that anyone can do. If you need help disconnecting a
battery terminal then get a friend to do it.
The computer has adaptive learning with regard to shift control. I used to
think it adapted to the driver, but now I know that it is for the purpose of
adapting to tolerances in the transmission including normal wear.
The TSB at www.hmaservice.com/webtec..._394890045 specifically recommend
this with regard to what they call shift flare on the 2-3 shift (engine
speed increases during the shift) or shudder on the 2-3 shift.
This procedure is completely harmless so you can do it for any problem or
any time you want to have some fun
The procedure is to be done with the transmission fully warmed up. If you
have been driving it should be warm even in cold weather. The engine coolant
warms the transmission fluid.
OK, when the battery is disconnected the adaptive learning is lost. So
disconnect a battery terminal then reconnect it.
Then Accelerate the vehicle through several 1-2-3-4 upshifts at small
throttle openings (approximately 25-30% TPS) until shift flare or shift
shudder no longer occurs. I assume 25 - 30% TPS is 25 - 30 % throttle.
(Another TSB says to use light and medium throttle openings)
As you can see in the TSB if adaptive learning does not solve the problem
the transmission is to be replaced.

the service manuals and electrical manuals, etc.
