Transmission fluid leak.
Got a transmission fluid leak and having trouble locating the total source. I think it might be the pan gasket but its hard for me to tell. It seems the fluid sprayed toward the back of the car. so the bottom of the car appears wet. Any Ideas of something I should check or tips on replacing the gasket. We don't have a lot of money so the cheaper the fix the better.

RE: Transmission fluid leak.
I don’t have any advice on the actual repairs of that model but I do have some advice on what can be mistaken for a leak. Many vehicles came to us that the owner's thought was leaking. When we checked into it, they were actually just over full and blowing the fluid out the vent. The owner was checking the fluid level incorrectly and adding fluid that wasn’t needed. So my first suggestion is to make sure that you are checking the fluid correctly by looking in the owners manual to see what the proper procedure is. Some are checked Sitting Level, Hot, in Park with the Engine Running. Some are checked Sitting Level, Hot, in Neutral with the Engine Running. Standards are usually checked Sitting Level, Cold, with the Engine Off.

If overfilling is not the problem Rupe may have some actual repair advice for you. Either way, please let us know how you make out in the end.

RE: Transmission fluid leak.
I'm not over filling it. The transmission starts to not shift well and slips alot so when its warm, I shift to N and put on the parking brake with the car running an it says no fluid. did this a few days ago and I added about 2qts and it ran alot better. then started doing it again and says its out again.

RE: Transmission fluid leak.
Most cars with an automatic are checked with the engine running but back to what Garner posted... is this the case for your car? Read the manual or seek advice from the dealer because incorrect level is a VERY common problem.

That said, even if the underside of the car seems wet there will be clues to where the leak originates from based on which side or how high you can spot the damp area. IOW, the wet area will generally not travel from left to right or up so look for the highest wet spot and stay focused on following the trail from dry to wet... then to the area that is really soaked. You should be able to narrow it down to within say 2 ft square and then look closer. The actual leak will seem clean (washed clean by the leak) but very wet. If you still have trouble then fill it to "full" by the book and slide a large piece of cardboard under the car over night to see where it drips the most. At this point it's time to get a good eye with good light under there to narrow it down further.

Bottom line is we can help you better once you give us more details on exactly what's leaking. If you feel the pan gasket is leaking then it probably wouldn't hurt to snug the bolts and check again over night. Worst case is it only slows the leak, but that's a start to finding the issue.

Let us know what you find and we can go from there.

Its the pan gasket. dried best we could put in 1qt drove it 3 blocks and around the pan was wet. Tried tightening it first and some of the bolt were loose.

RE: Transmission fluid leak.
If it keeps leaking you should probably get a Filter & Gasket kit. Look up the torque spec.s for the bolts, make sure that the pan is flat by tapping down all of the bolt holes, & do a fluid & filter change. This will give you a chance to look in the pan and see if it is still clean to give you an idea of the “health” of your transmission.

Thanks for the update.
