Transmission leak in your vehicle is an great problem. It occurs due to a crack in the transmission seal. This might appear as an innocuous problem but this can cause a problem to your vehicle in the long run, causing your vehicle to malfunction.
Difficulty level: Moderate. Though this is not a hard task, may require basic knowledge.
Time required: This does not take much time. It depends on your skill and size and type of the leak.
You need the following things to get this done:
(a) Transmission fluid with stop leak
(b) A funnel
(c) Gasket sealant
(e) You need an oil drip pan and empty container
(f) A new oil pan bolt.
Estimate cost: It depends on the type of leak and quality, quantity and availability of the fixture material.
1. Find the leak
First be sure that you have a transmission fluid leak. To determine this, you need to take the car to an area with a plane surface. Switch off the engine and if there is any leak, then the transmission fluid will leak out. It often comes at two places; at the front or back of the transmission.
2. Know the gravity of the leak
The next step is to know whether the leak is minor or major one. Minor leaks give out drops of fluid but major ones shed puddles of fluid.
3. Know where the leak is located
To repair the leak, you need to locate the leak exactly.
4. Drain out all transmission oil
To repair the leak, you need to drain out all the transmission fluid. Raise the vehicle up and make it safe with jack strands. Then find the transmission oil pan and make the fluid flow out. Put oil drip pan or empty container below to put all the transmission oil coming out of the engine.
5. Replace the gasket
Find the wrench and remove all the oil pan bolts using it. After removing the transmission oil pan, check the gasket on the drain plug. Replace the old gasket with a new one. It might be that the transmission oil is leaking due to the old gasket or exhausted drain plug. Apply gasket sealant to secure the gasket properly. It should be fixed tightly without cracks on it.
6. Test the threads thoroughly
Check the threads on the bolts completely. Replace the old bolts if those are old. If the bolts are not in good condition, then leaks might be created.
7. Fill up the transmission fluid
Now put the drain plug on. Fix the transmission oil pan with screws. Refill the transmission with fluid and stop leak. Stop leak is an additive which can prevent the seals from getting hard. This can prevent them from cracking and hardening. Use the funnel to refill the transmission. Funnel can prevent splashes.

1. Lucas oil (R) is most suitable for transmission fix. It comes with a white bottle with blue cap with a cost around $ 10.
2. Stop leak will also stop hard shifting in your transmission.
3. You need not add stop leak to the transmission if leaks are plentiful.
4. Do not fill your transmission excessively.
Things to watch out for
Leaks appear after the vehicles run for 75000 km or more. After the cracks form, there will be slow leakages and gradually that will develop transmission malfunction, resulting in the malfunctioning of the vehicle. So, be careful about it from the beginning.
