Here's why:
* It doesn't address the root cause: A leak indicates a problem with the transmission itself (e.g., worn seals, cracked case) or with the transmission pan gasket. Sealant doesn't repair these underlying issues.
* It can clog the transmission: The sealant can clog the transmission's internal passages, leading to malfunction and potentially catastrophic failure. This is especially true if the leak is significant or the sealant isn't compatible with your transmission fluid.
* It masks the problem: The sealant might temporarily stop the leak, making you think the problem is solved when it actually isn't. This can lead to more extensive and costly repairs later.
* Incorrect application: Applying it incorrectly will mean it doesn't work and makes a mess.
Instead of using transmission sealant, you should:
1. Identify the source of the leak: Locate precisely where the transmission fluid is leaking from.
2. Address the root cause: This might involve replacing a gasket, seal, or even parts of the transmission. This requires professional expertise and the proper tools and parts.
3. Get professional help: Take your Sebring to a qualified mechanic or transmission specialist for diagnosis and repair. They can properly identify the problem and make the necessary repairs to prevent further damage.
In short: While you *could* try transmission sealant as a desperate last resort for a tiny weep, it's far better to have a professional diagnose and fix the actual problem. The cost of fixing the underlying issue is almost certainly less expensive in the long run than dealing with a transmission failure caused by using sealant improperly.
