Fuel when my gas tank gets low my jeep dont shift out of first gear

Posted by on

  • Anonymous Feb 17, 2009

    My daughter came to me with the exact same problem with her '99 Grand Cherokee. She said whenever the gas tank got near empty, it wouldn't shift. Since there is no connection between tranny and fuel level, I told her I'd check it out. I've been driving it for over a month now, and every time the tank gets near empty, it won't shift out of first. Put more gas in, and it shifts fine.

In searching the internet, I found this is not an uncommon problem. I did find one case where the problem turned out to be the transmission speed sensor. Owner of vehicle reported that when dealer replace sensor, the Jeep shifted fine even when low on fuel.

Fuel level shouldn't have any bearing on shifting,sounds like you have tranny problems/or sensor(speed)problems

Hyundai sonatas was parked after normal drive, now will start and shift gears but won't get gas. I suspect a cat got in it and loosened a hose as one did our other car, I can't find where, any ideas


Not understanding what your asking, if it runs and shifts gears then it's getting gas, if it's acting like no power I would look for vacuum hose or considering the fuel pump going bad. Fuel pumps can be interment but eventually will fail. If tank is full probably work ok less than a quarter tank and the pump is out of the fuel and heating up.

Wont shift since ran out of gas


jeep ZJ 94.
no car runs, out of gas,,,, my dream do to this , has failed, 100 times.
HHO failed, and x,z,y.
even the match book cover, showing "turn water to fuel" fails.
im pulling your leg,

running out of fuel , likes to burn up fuel pumps.
they are fuel cooled and fuel lubricated. so dont do that. or $$$$$$$
after you ran it dry, the pump can fail, or have hard time priming.
long cranking to get the full system primed.
is engine running ok?, you failed to say that important fact...so.....
if engines ok?
does car go fast in 1st gear, fact 2 missing.....so...........???
wont shift can mean , tranny slips or wont go to 2nd, 3rd gear.???
which is it? slips? so skips?
or shifts late?
or shift too early.?

id reset the tranny TCM. (brain)

one way is to pull the battery neg cable for 5 min.
wait and put it back
all TCM have learn mode. so drive and teach it how you drive.
newer cars , 1trans, fists vast number of cars so it has an
even harder learn mode (not yours)

tell more get more......????????????????

the FSM is here.

I have no gears forward or reverse. My Vehicle is a 2003 Dodge Ram 1500 4x4 Hemi with 170,000 on the clock. Fluid is clean and full with no leaks. I have the following trouble codes:...


Your scanner will give you the code but it will not tell you how to fix your vehicle. Scanners basically tell you what systems to check or what systems are failing.

These are what your codes mean:

P0700: Transmission Control Module
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module. This is just a informative code.

P0734: Gear ratio error in 4th gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0732: Gear ratio error in 2nd gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0731: Gear ratio error in 1st gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0871: Transmission Fluid Pressure Sensor Switch C

P0876: Transmission Fluid Pressure Sensor Switch D

Emissions Codes:

P0400: Exhaust Gas Recirculation Flow Malfunction
- Harness or connectors (EGR volume control valve circuit is open or shorted.)
- EGR volume control valve stuck closed
- EGR volume control solenoid valve
- Dead (Weak) battery
- EGR temperature sensor and circuit
- EGR Valve

How to fix :
- Clean EGR Valve
- Repair EGR harness or connector
- Replaced EGR volume control solenoid valve
- Replaced EGR volume control valve

P0440: EVAP Emission Control System Malfunction
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0456: EVAP Control System Leak Detected (Very Small Leak)
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0441: EVAP Emission Control System Incorrect Purge
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

Based on the info check your EVAP system. I would check for leaks and maybe replace the EGR and the canister.

For the transmission check the TCM also you may need to take it to a mechanic though.

Hope this helps a little.

Car was low,low on fuel,put half tank in car.drove about 3miles onto 4lane and kicked it. when car tacked out in passing gear it started heasitating.eased off the accelerator and shifted fine.kicked it...


Replace the fuel filter. That should fix the problem. You can follow the fuel line back to the fuel tank to find it. It is usually in the middle of the vehicle near the edge of the vehicle, like right under the passengers or drivers door.

Engine stalling on a 2002 chevy tahoe z71


Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????
