Have a 2001 Santa Fe with approximately 120,000 miles. It is 2WD automatic transmission. While driving we have been noticing that the tranny seems to stay in 2nd and not changing to 3rd to make a smooth change in gear. If we use the manual mode of the transmission, we have no problem going from 2nd to 3rd to 4th. This happens only when we are in drive. Any idea what this can be and is it something that can be fixed without taking it to a transmission specialist knowing that they will say "It needs an overhaul" That is our experience anyway. Thanks.

Dear tbone,

At 120,000 miles, you are now at a point where three things routinely fail tied to the transmission:

a) Transmission input sensor
Transmission output sensor
c) Throttle position sensor

You can have a Hyundai dealer test these sensors before replacing. Have you gotten a Check Engine Light? If yes, get the codes read for free so we know what your problems are. Free OBD-II code reading at Checker Auto. Auto Zone or Pep Boys.

Have you had your transmission flushed and refilled with SP-III fluid or equivalent? I recommend this first, as it fixes your 2nd-3rd shift problem most of the time.

Byron

Where's my bailout?

Thank you Byron, We will get the transmission flushed and fluid replaced. We will let you know how it goes.

We see a lot of issues with the transmissions and input and output sensor needing to be replaced. Is this typical for Hyundais?

We had the transmission flushed and oil changed and what a wonderful difference!!!! Thanks for the input.

How do you find the output speed sensor and how difficult is it to change. We figure with so many miles maybe that will help even more. Any suggestions?

Actually...the only SM body Santa Fe to have drive-by-wire was the 3.5 liter from '03 to '06. 2.4 and 2.7 liter models had mechanical throttles.

[b]Hi I am brand new to the forum and am a great fan of Hyundai products. I previously owned a 2006 Hyundai Santa Fe and after 4 years purchased the new 2010 FWD sport version and got the car on December 22nd. 2009
Just for the record the 2006 had O downtime and I drove it for 106,000KM and did not even have to change the brake pads.

It is a different story with the 2010.

The transmission jerks and also a couple of times when I had parked in a multi- level parking I noticed that the car would jerk forward as I came down from each level and applied the brakes.
I currently have 10000KM on it. At 5000KM the dealer reset the transmission to the factory setting and told me that the problem of jerking as well as the clunking at slower speed should stop. It was okay for a while and it started again . Initially I was told by the dealer that the Transmission will need replacing. Well, I took the car in last week and was told that they have tried replacing the transmission in other cars but it still does not work and the problem seems to be the PCM. They have now ordered a PCM for me (I understand that this is like the main computer that controls everything).

I should say that the Hyundai dealer that I am dealing with here in Canada is great and I am really pleased to have purchased the vehicle from them. (I am not sure if the rules allow us to mention their name)>

I will report as soon as the PCM is installed and let you folks know the result.

Otherwise its a great car and I know they will have a fix and will resolve this issue. [b]

My understanding is Hyundai did not "PULL" the "OLD" transmissions from the parts distribution, so you may get the BUM trans till the new replacements roll into circulation... Now with TOYOTA, they change a part, the parts center is cleaned out of all the old style and disposed of, an refreshed with new design parts right now..

I have a 2006 Santa Fe and the transmission slips? I got a fuel throttle position sensor code once but nobody wants to fix it for me? Is it hard to get to? or the mechanic lazy?
