Transmission cooling lines

Here are the steps to install the transmission cooling line with a rubber seal on a 2001 Pontiac Grand Am GT:

1. Raise the vehicle: Use a jack and jack stands to lift the front of the car off the ground.
2. Locate the transmission cooler lines: The transmission cooler lines are located on the passenger side of the vehicle near the front of the transmission.
3. Remove the old transmission cooling line: Use a wrench to loosen the fitting where the old transmission cooling line connects to the transmission. Slide the fitting away from the transmission and let the old line drain.
4. Install the new transmission cooling line: Insert the new transmission cooling line into the fitting on the transmission. Make sure the rubber seal is securely seated.
5. Tighten the fitting: Use a wrench to tighten the fitting on the transmission. Be careful not to overtighten, as this could damage the fitting or the new line.
6. Lower the vehicle: Use the jack to lower the vehicle back down to the ground.
7. Check for leaks: Start the engine and let it run for a few minutes. Check for leaks around the fitting on the transmission and around the rubber seal on the new line.

If you need additional assistance or want to see a video tutorial, I would recommend searching for videos on YouTube that specifically cover the installation of transmission cooling lines on a 2001 Pontiac Grand Am GT.

Nothing will happen. Removing the pan is to change the filter and get more fresh oil in the system . Look at the color of the fluid red is new brown is replace me soon in 10k or so black is yesterday or replace trans in 10k or less.

That is a VERY easy radiator.
Loosen radiator drain plug and drain coolant from radiator.
Disconnect cooling fan connectorsRemove upper and lower radiator hoses after marking them to ease installation.
For vehicles equipped with automatic transaxles, disconnect transmission cooler lines at transaxle.
Remove air conditioner condenser fixing bolts and radiator bracket fixing nuts.
Remove the radiator, radiator cooling fan, air conditioning cooling fan and transmission cooler lines from the vehicle as an assembly.
Transfer all necessary parts (fan assemblies, cooler lines, clips, speed nuts, fittings, etc.) to the new radiator.

Reverse procedure to install.

Fill and bleed cooling system.

usually there is not a drain plug. If you are changing fluid, consider a lube shop with a T-Tech style flush machine. This machine pushes in new fluid while removing old fluid. MUCH more complete as it gets torque converter, cooling lines, passageways, and trans cooler. you simply cannot drain all of those areas without this methodology. Also change the trans filter, it is inside the pan.

Your transmission is probably overheating. How many miles are on the vehicle, and have you had the transmission fluid flushed, and filter changed lately?

You could 1st start checking the fluid flow thru the radiator cooling lines by removing the lower trans. cooling line, aim the hose into a drain pan then starting the vehicle in park with an assistant. Make sure you are getting good circulating flow from the cooling return hose. The radiator coolers can plug partially with clutch material and cause an obstruction. A cooling line backflush would be needed to clear it.

If fluid flow is good, I would also change the transmission filter to make sure it is not a fluid obstruction there. Make sure you use mercon V fluid and don't overfill the transmission level while replacing the drained out fluid amounts.

The transaxle light blinking will set codes in the computer and you will need a transmission scanner code reader to have them read, usually a good repair shop or dealer can help.

You need to replace more than the fluid, you need to change the filter. What happens is the filter can plug, and drop fluid pressure, then the clutches slip and burn.

You may want to consider having a lube shop, equiped with the T-Tech flush machine to do this job. If you drop the pan, you cannot drain the torque converter, cooling lines or cooling radiator. The t-tech machine puts in new fluid until clean fluid comes out...

If your getting coolant introduced to transmission fluid or vise-versa, you need to change rad & make sure you flush both cooling system & especially transmission thoroughly a.s.a.p. before it takes out the transmission, if damage hasn't already been done.

As detailed as I can :
Drain the cooling system. Detach the air conditioning line .Raise the vehicle. Remove the lower radiator splash shield. The splash shield is equipped with hinges which should be treated with care on removal. Remove the radiator splash shield. Detach the securing clips. Remove the radiator splash shield. Seal the line and the evaporator with plugsDetach the air conditioning line. Detach the lower coolant hose. Remove the air conditioning condenser. Remove the securing screws. Vehicles with manual transmission, cable tie the cooling radiator. Detach the automatic transmission/power steering cooler. Remove the securing screws. Detach the automatic transmission/power steering cooler. Lower the vehicle. Remove the radiator foam trim. Remove the radiator. To install, reverse the removal procedure.
