1999 Toyota Camry 2.2L V4 automatic 112,000 miles
Last week I checked my transmission fluid and it was very low. I added fluid and checked it the next day and it was low again. I noticed trans fluid on the front of the pan so i went out and bought a new trans filter and a new trans pan gasket and replaced them, sealed and bolted the trans pan back properly, and added the fluid. I thought that this would fix the leak but I see that the pan is still leaking from the front of it. Any ideas on what the issue is?

Make sure you are applying the correct torque to all the bolts...too high and you can crush the gasket. Also, it can take a repeat tightening around the pan as the gasket sets. Finally, there may be damage to the sealing face on the pan or tx case that prevents getting a good seal.

Here are some potential points for leaks:
1. Differential or transmission filler plug gaskets.
2. Transmission cooler connections loose on transmission or radiator.
3. Transmission cooler hoses cracked.
4. Gasket or sealant on bolts which seals carrier cover.
5. Park/Neutral Position Switch shaft seal.
6. O-rings on union and elbow by Park/Neutral Position Switch.
If you're sure it's the pan gasket that's leaking:
1. Make sure you used the correct torque and use a cross-hatch tightening pattern from the inside out, rather than the tightening the bolt pattern from the corners in.
2. Try using Toyota black form-in-place-gasket material (FIPG, Part No.08826–00080 or equivalent) instead of the gasket. It's not as convenient, but when used correctly, it is better than a gasket as a seal.
• Thoroughly clean all components to remove all the loose material.
• Using a non–residue solvent, clean both sealing surfaces.
• Install a nozzle on the sealant tube that has been cut to a 3–5 mm (0.12–0.20 in.) opening.
• Apply seal packing to the pan as a complete seal around the circumference, surrounding all the bolt holes.
• Parts must be assembled within 5 minutes of application. Otherwise the material must be removed and reapplied
