Hyundai Tucson: Hydraulic System / Fluid Repair procedures

Service Adjustment Procedure
Oil level Check
   
A check of ATF level is not normally required during scheduled services. If an oil leak is found, perform the oil level check procedure after repairs are completed.
   
When checking the oil level, be careful not to enter dust, foreign matters, etc. from fill hole.
1.
Remove the eyebolt (A).

Eyebolt tightening torque:
2.9 ~ 4.9 N.m (0.3 ~ 0.5 kgf.m, 2.2 ~ 3.6 lb-ft)

   
Always replace the gasket of the eyebolt use new one whenever loosening eyebolt.
2.
Add ATF SP-IV 700cc to the ATF injection hole.

3.
Start the engine.
(Don’t step on brake and accelerator simultaneously.)
4.
Confirm that the temperature of the A/T oil temperature sensor is 50 ~ 60°C(122 ~ 140°F) with the GDS.
5.
Shift the select lever slowly from “P” to “D”, then “D” to “P” and repeat one more at idle.
   
Keep on each speed position more than 2 sec.
6.
Lift the vehicle, then remove the oil level plug (A) from the valve body cover.

   
At this time, the vehicle must be at a level state.
7.
If the oil flows out of the overflow plug in thin steady stream, the oil level is correct.
Then finish the procedure and tighten the oil plug.
   
Oil level check (excess or shortage) method
Excess: Drain quantity exceed 900cc for tow minutes.{50 ~ 60°C (122 ~ 140°F)}
Shortage: No drain.
   
If there is no damage at the automatic transaxle and the oil cooler, the oil cooler hose, transaxle case, valve body tightening state are normal, ATF must drip out after performing above 1 to 7 procedures. After performing above 1 to 7 procedures, if the oil doesn’t drip out, inspect the automatic transaxle assembly.

Driving in rough road (Bumpy, Gravel, Snowy, Unpaved road, etc)
Driving in mountain road, ascent/descent
Repetition of short distance driving
More than 50% operation in heavy city traffic during hot weather above 32°C(89.6°F) .
Police, Taxi, Commercial type operation or trailer towing, etc
1.
Remove the drain plug (A) and reinstall the drain plug after draining ATF totally.


Drain plug tightening torque:
38.2 ~ 48.1 N.m (3.9 ~ 4.9 kgf.m, 28.2 ~ 35.4 lb-ft)

   
Replace the gasket before reinstalling the drain plug.
2.
