Hi,
My 2004 Hyundai Elantra GT Automatic Transmission, is having some shifting issues.
P0455 – P0733 – P0734 – P0750 – P1529I start the car, put it in Reverse, back out of my parking spot, then put it in Drive, and GO
So I am driving down the road, get up to 20mph, It shifts to 2nd,
then it shifts into 3rd for half a second and drops to 1st and just revs,
As soon as it drops under 15mph, I can hit the GAS and it will speed up to 30mph but WONT shift out of first anymore.
If I come to a stop put it in Park then back to drive it will shift from first to second then third for half a second and drop back to the 1st gear rev thing.I disconnected the external Wire harness to the transmission (Solenoid/Temp Sensor)
Dried out the moisture and wiped off coolant off the the top of the trans that did not get cleaned up when the Thermostat was changed
I drained the trans fluid (there were NO metal chunks or pieces in the fluid but it did have a slight burnt smell)
Then put in fresh Hyundai Sp3
Plugged the Harness back in and cleared the codesWent for a drive and same problem came back 1st to 2nd then 3rd dropped to 1st and revs.
Scanned codes and only got P0733 – P0734 – P1529
Rechecked the Transmission Fluid it is full and smells good.What do I do next?
Did Coolant on top of the trans kill the ISS and/or OSS and/or VSS?
If so, How do I test them?Do I have to remove and test all the Solenoids?
If so, what are the Resistance Values?What else could it be?
Any ideas?
Thanks a Bunch

I already read that TSB last week
So by you sending me the TSB, you think it is Solenoid related and NOT the VSS, ISS or OSS?
I don’t own nor do I have access to a “Hi-Scan Pro”I just have a Multi Meter
Do you know the OHM readings the Solenoids should be at?
or should I just remove them and put 12volts on them and see if they click?[quote=”Cosmo Tigato” post=183843][quote=”college man” post=183840]see if this helps.

and clicking is heard the harness is ok.[quote=”college man” post=183844][quote=”Cosmo Tigato” post=183843][quote=”college man” post=183840]see if this helps.

so I went ahead and removed the side pan to expose the solenoids and applied battery power to each
of the five and all of them worked (clicked).If there is a clog in the solenoid, should I remove each solenoid and spray brake clean in the center hole of each,
then apply power and spray again?Or is it new transmission time?
thanks
Okay so,
I decided to remove the Solenoids and clean them.
I sprayed brake clean in the center hole and it shot out the bottom hole
then I applied power and sprayed the center hole and it shot out the top hole
GREAT!!! they all seem to work.
So I thought that it must be something else wrong with the transmission.Well just for the fun of it I took out my Multi Meter and checked each one for resistance.
First one 3.5ohm
Second one 3.5ohm
Third one 27.4ohm <———–
Forth one 3.4ohm
Fifth one 3.6ohmLooks like I found the problem.
I am going to order a new Solenoid.
Or
I might just order a whole set of 5 new ones.I will let you know what happens when I reinstall and test drive.
Thanks

cool keep us posted.
Great news,
The shift solenoid showed up in the mail today.
I tested it by poking a couple of hols in the pouch with the multi meter probes — 3.5ohm PERFECT
So I installed all 5 solenoids back in to the valve body.
Sealed the side pan and 15 bolts later,
added 5 quarts of SP3,
Re installed the Radiator,
connected cooler lines,
Started the car, waited for it to warm up.
Shifted to each gear (10 seconds each)
Closed the hood.
Put in in reverse,AND
Backed out of my parking spot – YIPPY!!!!
Put it in Drive and nothing!
No forward gears,
So I pushed it forward to the parking spot.
Then went to each gear and nothing was engaging.
Reverse was not working anymore.So I was confused. No CEL No Gears, Just revs up. BUMMER!!!
DID I MISS SOMETHING???
[quote=”college man” post=184260]Not sure what to tell you? Either the harness has a problem or the trans
may have a problem.[/quote]It makes a Gurgling sound from the dip stick tube.
And a strange sound when I shift to Rev. or Drive.There are no metal bits in the Fluid.
I will open it up again tomorrow, to see if I missed somethingThe solenoids aren’t the problem as you have replaced them. You need to do the following:
1. Check all sensors. Could be speed sensor, but I would test all the sensors and make sure they are at spec.
2. Check transmission line pressure.
3. Swap the transmission computer out. You should be able to get one from a junk yard.If none of those are the problems, then I am afraid your transmission is toast.

I DID MISS SOMETHING!!!
After thinking about it, I realized that the Solenoids must have popped out.
And yes I then remembered, someone forgot to bolt the solenoid supports back in. (ME)
they were still in the box of parts, folded in a paper towel at the bottom, no wonder I missed them.So I took the transmission apart again, and sure enough 2 of the 5 solenoids were completely out.
I popped them back in and bolted in the support brackets…Put the whole thing back together, and filled it with SP3…
Went for a drive and then CEL came back on P0733.
All the solenoids are 3.5 ohms
So next thing is to test the Wire Harness.Does anyone have a pin out diagram for the transmission harness connector?
Thanks
So searching around the Super Information Highway got me this link;

Now I can check to see if I have a wire harness issue.

If it was one of the speed sensors Would I get:
P0715 – Input Speed Sensor, Open Circuit/Short Circuit?
or
P0720 – Output Speed Sensor, Open Circuit/Short Circuit?[quote=”Cosmo Tigato” post=184441]So searching around the Super Information Highway got me this link;

The Transmission Wire Harness checks out fine.
The Temp Sensor is a bit out of spec, but I don’t think that would cause a 3rd gear problem.
