I need to fill the transmission fluid on my 94 trooper but cannot find the filler cap

gear + BOX
so is the transfer case, box. or the 5 speed stick box or?
what?
we drain it then fill it, to the mark.
on all gear boxes.
if A/T we RTM read the operators guide. for how to do it right,
most dont and wreck the tranny. the #1 reason they removed the filler.
when posting car issues, stated what it is.
like this.
95 Trooper, 4wd M/T , i want to change the 5speed box lube.
what do i need to do that.?
ill spin the wheel of fate, and land on 5speed box.
and answer for TR5 and NV1500 boxes.

For all transmissions except for the Borg-Warner T5R, replace the transmission fluid at the first 15,000 miles (24,000 km) and then every 30,000 miles (48,000 km) thereafter. The Borg-Warner T5R transmission does not require periodic changing of the transmission fluid. (they lie)

1. Raise the vehicle and support safely on jack-stands. Place a fluid catch pan under the transmission drain plug.
2. Remove the fill plug from the side of the transmission, then remove the drain plug. Be cautious when removing the drain plug: the transmission fluid can be very hot. Allow the transmission fluid to drain into the pan.
3. Install the drain plug and tighten to 20 ft. lbs. (27 Nm) for all models except the 1996 Hombre, which requires 27 ft. lbs. (37 Nm).
4. Refer to the manual transmission fluid recommendations for the proper viscosity of engine oil, or type of transmission fluid to be used for the T5R and NV1500 transmissions. Fill the transmission by pouring the new fluid through the fill plug hole in the side of the transmission. Fill until the fluid starts to dribble out of the filler hole. Install the fill plug to 17 ft. lbs. (23 Nm), then lower the vehicle.

so next you ask, what fluid
sure.
Use engine oil for all of the manual transmissions, except for the Borg-Warner T5R and the NV1500 (1996 Hombre). Make sure to use engine oil of the correct viscosity for these transmissions, as follows:

• Except 1992-96 Rodeo and Trooper, high temperature-SAE 40
• Except 1992-96 Rodeo and Trooper, normal temperature-SAE 5W-30SF
• 1992-96 Rodeo and Trooper, high temperature-SAE 15W-40, 20W-40 or 20W-50
• 1992-96 Rodeo and Trooper, normal temperature-SAE 5W-30

he Borg-Warner (B-W) T5R is found on Rodeo models with the V6 engine. The 1991-93 B-W T5R uses DEXRON-II automatic transmission fluid, whereas the 1994-96 B-W transmission uses DEXRON- III automatic transmission fluid.

use the highest Dexron number, on the shelf, mark III is not made today.

1999 Isuzu Troopers w/automatic transmissions do not come with a dipstick. It is a sealed transmission just like a manual transmission. The fluid must be checked by removing the fill plug. Emergency brake on, engine running,warmed up ,vehicle in neutral. When removing the fill plug ,which is on the side of transmission- at the top, fluid should slightly drip out. If fluid doesnt drip out you need to add fluid. You will need a small hand pump to fill it.

There isn't one. You need to climb under it and remove side filler plug on trans (with vehicle warmed up and on level ground) Correct level = dribble of trans fluid from fill hole.

Transmission Fluid Fluid Level Checking & Filling To Check:

1. Connect a scan tool to the vehicle to read ATF temperature. ATF checking temperature should be 95° - 113°F (35° - 45°C).
2. Start the engine.
3. Raise and safely support the vehicle.
4. Place a drain pan under the transmission.
5. Allow the ATF temperature to reach 95° - 113°F (35° - 45°C). Automatic transmission fluid inspection plug
   
   
6. Remove the inspection plug from the transmission housing. Fluid is pipe will run out. If fluid continues to drip out, no additional fluid is needed. If only the fluid in the overflow pipe runs out, additional fluid is needed.

To Fill:
Automatic transmission fluid filler pipe

1. Pry the cap from the filler pipe. The cap locking device will be destroyed during removal.
2. Pull the plug from the filler pipe.
3. Add fluid slowly with VAG 1924 or equivalent until fluid runs out of the inspection hole. Install the inspection hole plug.
4. Install the plug in the filler pipe and secure with a new cap.

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.

look at trans pan there should be 2 sump plugs in pan one slightly higher than the other, fill till oil just comes out of higher level plug while engine is running.

best to get a look at a manual and that should solve you problem

the cavalier transmission has a level check plug , its between the bell housing and the axel tube on the torque converter side of the transmission , has to be done from under the car , by removing the check plug if fluid comes out its full if no fluid comes out add fluid accordingly . the cap you did find is the fill point only .

Lee2fixit doesn't know what he talks about on 99 Rodeos.

There is no dipstick tube - there are two access holes on the side of the transmission. The bottom one is to drain it out. The top one is to fill it back up. It is full when the fluid comes up to the bottom of the top hole.

Or you can take it to a dealer or service center to have it done.
