    This code represent a problem with the Trans fluid temperature sensor's range/performance. The only thing you can do here is ckeck connections (connectors) to it. If you don't find any problems with the wiring/connectors, replace the sensor. However, I'm not aware of any instances with this sensor causing a drivability/performance issue. Here's an excerp:
    P0711 Oil temperature sensor rationality

    check (See 2005 Tucson Shop

    Manual, Page TR-188)

    • MIL on

    P0712 Oil temperature sensor - short circuit

    • MIL on

    • 2-3 shift flare

    P0713 Oil temperature sensor - open circuit

    • MIL on

    • Harsh P-R or P-D engagement

    • Damper clutch does not engage

    • No 4th gear engagement (1996-2000 Elantra, 1997-

    2001 Tuburon, 1995-2005 Accent)

    • 2nd gear hold (1999~ Sonata, 2001~ Elantra, Santa

    Fe & XG, 2003~ TIburon, 2005~ Tucson)

This DTC code is set when the ATF temperature output voltage is lower than a value generated by thermistor resistance, in a normal operating range, for approximately 1 second or longer. The TCM regards the ATF temperature as fixed at a value of 80 °C(176°F). Solution: Eliminate wiring as the cause. Once you've done that, Recommend you replace the sensor. Otherwise, take the vehicle in to a Hyundai Shop and pay the diagnostic fee. They'll tell you what the problem is and the cost to repair it (parts, labor, & tax).

Slow pickup on takeoff

You don't specify make, model, year, engine or transmission, but if an auto, a common cause of this is failure of the 1-2 shift solenoid in the trans, meaning that it cannot find low gears, hence the sluggish takeoff.

It is not an expensive part, but it is best to have the vehicle on a hoist as the trans pan must come off. Also this fault should cause the check engine light or the overdrive light to blink a trouble code.

My 1995 Nissan pickup xe truck when I put it in drive it will not shift out of first and once I get to the speed of 25 miles a hr. it shifts into neutral until it goes down to appx. 15 mph then it kicks...

V6 or I4 engine? xe = i4?
bad tranny.?
low or too high ATF levels.
clogged bottom filter before pump, (shifts hot?)
RE4 trans is 4speed electronic
RL4 xxx trans is manual only
this side of your tranny has a tag is it RL/RE4 or or 3speed.

3 speed or 4 speed the FSM show four A/T used then .
there are 5 tranny total then ,4 AT (1 m/t)
on car diagnosis varies greatly by type.
fluid checks (if electronic the Tcm blink codes (DTCS)
pressure checks. for weak pump.
that stall rpm tests.
here is one used on your car

PO 171 and PO174 codes but different problem

transmision shifts are based on engine load imputs a 171 and 174 refer to a lean condition therefor the shift is being based on an assumed cold engine so yes it may be related

I have a 1999 Ram B 1500 Van, auto transmission, 5.9 L engine.
Same problem, trans hesitates in 2-3 upshift, sometimes 1-2
to 2-3 upshift. Posts trouble code P1756 - Transmission Govenor pressure too low at below 15 to 20 Psi. Transmission pump shot or valve body leak stops trans from reaching proper pressure to shift, which is minimum 15 Psi.
Either trans is leaking in valve body, valve is stuck, shift solenoid on valve body is sticking, or pump is shot.

My shifting is weird

You have a trans issue, have the system self tested for codes, Kragen auto and others do this for free. Get back to me with the trouble codes.

Problem code po711. what is this? Will not let car complete the inspection for North Carolina.

This code is set by the TFT, that is the tranmission fluid temperature sensor, have you towed anything lately that might have overheated the trans? If not erase the code and drive it, it may be a fluke.
