How much transmission fluid is needed for 2000 hyundai elantra auto trans and should i only use sp111?

make sure that you have the proper amount of transmission fluid. If the tran still has issues then it could just be that the gears on the inside of the transmission need to be rebuilt or replaced.

- Spark Plugs (make sure they are gaped properly)
- Spark Plug Wires
- Coil Packs (if needed) or Distributor Cap & Rotor (which ever so equipped)
- Air Filter
- Fuel Filter
- Oil
- Oil Filter
- Transmission Filter (optional)
- Transmission Fluid (optional if you do change the trans filter you will need the fluid)
- PCV Valve (optional)
- Bottle Of Fuel Injector Cleaner (add to fuel tank kind)

Your transmission fluid is dangerously low (tranny is dry). The pops & jerks are the transmission
internal components trying not to seize onto each other due to lack of lubrication and/or overheating.
Low transmission fluid leads not only to loss of lubrication but lots of overheating (of the tranny).
The loss of Elantra performance (speed tops out at 55), is caused by power loss due to friction inside the transmission. All your power is lost overheating the transmission (toward destruction), instead of
being transmitted through the transmission to the wheels.

The 2004 Elantra takes Hyundai SP-III Automatic Transmission Fluid, with 8.4 quarts used in a
total refill - but just 5 quarts at a fluid change. For How-to transmission fluid change instructions:

www.autozone.com claims that 2004 Hyundai Elantra can take these non-Hyundai ATF's:
Lucas Semi-Synthetic Multivehicle ATF
Pennzoil Muilt Vehicle ATF
Valvoline Maxlife Dex/Merc ATF
Castrol High Mileage ATF

no,no,no........ do not use dextron in a hyundai, if you do you will be buying a trans in 3-4 months you can use, hyundai fluid itself, or you can use chrysler type 7176 or mitsubishsi trans fluid, avalible at any parts store, even wallmart.

You should have some type of guarantee from a car lot or dealer. If private seller, then go to a reliable trans shop and have them change the trans filter and fluid. Its not good to have oil there, but it is not caustic and a trans shop should do ya.

DTC P0734 is "4th gear incorrect ratio" - that's your torque converter 'LOCK UP Clutch" It's worn out (or you're using the wrong Trans Fluid required by Hyundai - SPIII OR Both). The P1624 is simply the Trans Control Unit (computer) communicating to the Engine Control Module (ECM computer) MIL - on request signal to ECM = asking it to turn on "Check Engine" light. MIL = Malfunction Indicator Lamp. When the torque converter 'lock up" clutch slips or doesn't engage, the trans automatically returns to 3rd gear and stays there (it's called 'fail safe' mode) until you cycle the ignition key, then everything resets until the malfunction occurs again.
You'll need to have an AT (Automatic Transaxel) tester hooked up to verify this. Hyundai has a Service Bulletin specifically for "gear incorrect ratio' codes. If when you changed the trans fluid, was it done at a Hyundai Service Center? If not, someone may have installed the wrong fluid.

bad news, generally when you transmission slips like that its either low pressure (not very common) or burnt clutches in transmission (more common). check color and odor of tranny fluid, that should be what tells you for sure. if fluid is dark and stinks you most likely need it overhauled, or replaced. hope this helps. dustang

drain the the fluid from the gear box .and refill with a good auto transmission fluid a.t.f. as the fluid breaks down due to heat

Hey Cliff_harris,

The Tranny fluid needed is Hyundai SP-III ATF

Hope I've helped,

I don't know if I can help but as an owner of a Hyundai Elantra 2000 GLS with 205,000 miles and the original clutch and transmission I'll try and help!

I always start with the lowest cost solution first and avoid mechanics as much as possible!

Have you checked the trans fluid?
It should be changed every 30,000 miles!
Sometimes a Lucas Trans Fluid will cure - fix slippage!

Have you checked for a clutch adjustmet!
An adjustment can cure - fix slippage!

Are you a clutch rider with your foot always on the clutch?
If so you may have worn out the clutch!

How many miles to you have on your Hyundai Elantra 2000?
