Most likely a dirty filter. also the slip can be coming from the tranny being dry. my bro has a 94 camero put all new seals in and still leaks. sometimes transmissions malfunction and build too much pressure inside and need rebuilt

SOURCE: 2.3l ranger keeps overheating, been through two radiators already.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

Theres a smell of gear oil in the cab when driving.What could it be?


(1) motor oil only smells when its being burned.
(2) the output of the air ducts is in front of the gear shift area.
So, I'm thinking that you have an oil leak in the engine compartment (which may be dripping onto the exhaust system), and the oil has found a hot part of the engine/exhaust, and the smell of heated oil is wafting through the cabin air filter into the passenger compartment through the air ducts in the middle of the dash to just above the gear shift area.
If my theory is correct, you should be able to re-route the burned oil odor by changing the setting of your air ducts by changing the setting from its current setting to a "defrost-type" setting, wherein air entering the passenger compartment comes from the ducts below the windshield, rather then entering through the openings at the center of the console.
Ultimately, your fix will be to locate and resolve the oil leak.

Here's your list of possible culprits for the 1997 Nissan Pathfinder

Priority Action Part Type Cause
1 Inspect - Valve Cover Gasket -- Valve Cover Gasket Leaking Oil.
2 Inspect - Oil Filler Cap -- Oil Filler Cap Damaged or Missing.
3 Inspect - PCV Valve -- Plugged or Damaged PCV Valve.
4 Inspect - Oil Pan Gasket -- Leaking Oil Pan Gasket.
5 Inspect - Head Gasket -- Leaking Head Gasket.
6 Inspect - Oil Pump - divided O-ring or Oil Pump Gasket

If the odor really is gear oil (aka transmission fluid) and not motor oil, then there's a leak coming from the automatic transmission/manual transaxle.
Look under the transmission after the car has been parked awhile, and look for a reddish oil spot/blot/pool. transmission fluid is dyed red just for the purpose of differentiation from other automotive lubricants. You can assist the process of color differentiation by putting newspaper under the vehicle once it's been parked for the night.
Placing enough newspaper may also keep your Pathfinder from depositing a nearly-impossible-to-remove oil stain onto your garage floor overnight.
If you already have an oil stain on the floor, try a spray can of engine degreaser first. Citrus degreaser next.

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.

What kind of auto trans fluid


The 2003 Sunfire has been updated from Dexron II or III to Dexron VI per a Technical Service Bulletin from GM.

Automatic Transmission, 4T40-E Initial Fill..........6.5 liters
Automatic Transmission, Total Fill 4 speed 4T40-E..........12.2 liters


Good luck and hope this helps, if you do use Synthetic transmission oil, make sure it's a Low Viscosity Synthetic Transmission oil. High viscosity transmission oil will cause the gear shifting to stick and will cause shifting issues.

Thank you for using fixya and good luck.

Where is the dip stick for transmission oil


Looking at the motor from the front, in the middle all the way to the back, near the windshild. It has a red o-ring handle. Three speed 3T40 transaxles (2.2L only) will have a dipstick, whereas the four speed 4T40-E (2.2L or 2.4L) will not have a dipstick. The 4T40-E has an oil check plug located above the pan in the center of the torque converter side of the transaxle; it is recommended to check fluid only when a leak has occured.

Good job.

Why wont my transmision shift


Have you checked your transmission fluid lately?
More often then not that is the cause of shifting problems. Normally this happens gradually which is to be expected since transmission leaks are usually slow. The first signs are a slight hesitation when the car is first started in the morning and put in reverse. The the car seems to lag just a bit before moving back. This increases as more fluid is lost.
Another cause is from the transmission not being properly serviced. Leave the tranny fluid in to long and it becomes burnt. At this point it the viscosity is more like cooking oil instead of transmission fluid.

Most people neglect this item because of a lack of understanding about the transmission system. As opposed to the engine that everyone knows NO Oil =No Car. Although the service interval is greater when compared to the engine oil it needs to be taken care of to prevent "No Car" also.

Check your tranny fluid. Open the hood and located the tranny fluid dip stick. Usually along the firewall. Read what it says because normally the car needs to be running and in neutral to get an accurate reading.

Also look and smell the oil on the stick. If it's brown and/or it smells like it's burnt have the tranny serviced. This involves draining the fluid, replacing the filter and new fluid.


I hope this helps and good luck.

How do you check the transmission fluid -wheres the dip stick


According to the manual if the transmission is leaking fluid or shifting incorrectly take it to the dealer. Other than that the service interval for filter and fluid change is 100,000 miles. There is a 7/16 plug on the transmission case you have to be under the car to see it. it is located on the backside near the right axel. You take it out and put in transmission fluid till it comes out the plug hole. The fill plug is accessed from engine compartment,you will need a long funnel to fill. It's a must take it to a Dealer for service unless you want to try to service it your self. Good luck friend. 
Here is how you add fluid:Start the engine and allow the engine to idle until the transmission fluid temperature has reached the value specified. 
Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range. Remove the fluid vent cap. 
Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range. Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening. 

Remove the transmission oil level control plug.147643_trans_1.jpg this trans only has a fluid vent cap that you can unscrew to add fluid.
