Hyundai: 04 Sonata trans, again

There is a TSB out for re-programming the shift patterns/adaptive learning
function of this transmission----

I had it applied to my '04 Sonata GLS V6 2.7L and that cleared up all these
shifting problems for me--

TSB # 04-40-006-1

Take the car in and ask that this TSB number be applied to the TCM. It is
free of charge.

Hope this helps--

My 03 has been doing the same thing since I got that software update a
while back. It's irritating as hell.

Ooo... That'sa new one. I'll have to go get that applied. I'm due
for an oil change anyway.

There's nothing there that sounds terribly abnormal. The trans will tend
not to downshift unless you're putting the engine under load. If you slow
down enough, it may choose first gear. If you have no trouble codes, then
most likely the dealer is correct.

The reprogram cited does not apply to your vehicle. That programming is
already in the trans computer in 04 models. The reprogramming only
applies to 02 & 03 models which had different original programming. This
reprogram was to solve a 2-3 shift flare.

Sorry, you're right hyundaitech---

TSB 04-40-006 was superceded (with the -01 designation at the end) to NOT
include the 2004 model year. The original one (without the -01) included my
production date. Hmmmmmm, I had it applied to my car and it improved my
shift quality, flare and delayed 2-3 upshift when the engine is cold.

What gives here?

I suppose it's possible it could have some unwanted effect on the 04's.
Most likely, on attempting to reprogram, the scan tool simply says
"already reprogrammed" or "ECM is a different type." The bulletin
specifically says the bulletin was superseded to change the vehicles
affected. I won't be able to get any further info than that from Hyundai
-- they guard it closely.

Yeah, that's why I traded my LEMON Chevy Venture in, a higher quality
vehicle? Haven't you ever heard of the Piston Slap that GM says is "normal".
Check out www.pistonslap.com and see how high GM's quality is.
So much for the higher quality in North American vehicles.
