How to add fluid to manual Transmission

The manual trans-axle has a drain plug located between the two support bars that run from front to back underneath the unit. However, removal of the speed sensor is required. There is an electrical connector that must be disconnected. The retainer clip for the speedometer cable must be removed along with the speedometer cable. Pry the speed sensor from the trans-axle. Use the end of the speed sensor to check the level of the fluid. Here are diagrams below to help you see what I am talking about.

If you have an automatic transmission, you fill it with a transmission funnel through the dipstick. If you have a standard shift, you fill through the plug that is about half way up the transmission, fill till fluid is level with the bottom of the plug hole!

Checking and adding fluid.
Escort, Tracer & Probe
Ensure vehicle is level. To check fluid, remove retaining bolt and pry out speedometer driven gear assembly (analog cluster) or vehicle speed sensor (digital cluster) from transaxle. Wipe fluid from driven gear and housing. Reinsert driven gear assembly (analog cluster) or vehicle speed sensor (digital cluster) into transaxle, then remove again and check fluid level.
All Others
Ensure vehicle is level. Check lubricant level at filler plug hole on side of transmission. Lubricant should be within 1/4" of filler hole bottom. Add lubricant as necessary to bring to correct level.

good luck

You fill the gear oil until you can feel the oil on the filler opening hole. Make sure you use the correct gear oil.

Hello.

I have attached a picture item number 2 is the dip stick. This is where you check and service.

Hello.

Sorry, late night. Try this one.

Transmission Fluid Check

The transmission fluid level should be checked only with the vehicle parked on level ground.

Be sure the vehicle is on level ground and apply the parking brake.
Disconnect the electrical connector from the Vehicle Speed Sensor.
Disconnect the speedometer cable from the VSS.
Remove the VSS bolt and gently pry out the VSS.
Check the fluid level.
If necessary, add transmission fluid.
Position the VSS. Install the VSS bolt. Tighten the VSS bolt to 8-12 N-m (69-104 lb-in).
Connect the speedometer cable.
Connect the VSS electrical connector.

Transmission Fluid Drain

Raise and support the vehicle.
Clean the transaxle drain plug area.
Remove the drain plug and drain the fluid into a suitable container.
Install a new washer and tighten the drain plug to 39-54 N-m (29-40 lb-ft).
Lower the vehicle.

Transmission Fluid Fill

Disconnect the electrical connector from the Vehicle Speed Sensor.
Disconnect the speedometer cable from the VSS.
Remove the VSS bolt and gently pry out the VSS.
Place a funnel into the Vehicle Speed Sensor (VSS) mounting hole.
Add the specified transmission fluid until the "full" level on the VSS is reached.
Position the VSS. Install the VSS bolt. Tighten the VSS bolt to 8-12 N-m (69-104 lb-in).
Connect the speedometer cable to the VSS.
Connect the VSS electrical connector.
