Here's a breakdown of what you should do instead:
1. Diagnose the Problem:
* Identify the symptoms: What's wrong with the transmission? Is it slipping, making noise, refusing to shift, or something else? Be as specific as possible.
* Check the transmission fluid: Is the fluid low? Is it dirty or burnt (smells burnt, is dark brown or black instead of reddish)? Low or dirty fluid is a common problem and *might* be a simple fix (fluid change and filter replacement), but it's unlikely to solve major internal problems. Do not attempt a fluid change if you are not mechanically inclined.
* Get a professional diagnosis: Take your Stratus to a reputable transmission specialist or a trusted mechanic. They have the diagnostic tools (scanners, etc.) to pinpoint the problem. This is crucial before any repair attempt.
2. Repair Options:
Based on the diagnosis, your options will vary significantly in cost and complexity:
* Fluid and filter change: This is the cheapest and easiest potential fix, but only addresses minor issues.
* Transmission rebuild: This involves disassembling the transmission, replacing worn parts (e.g., clutches, seals, bands), and reassembling it. This is expensive but can restore the transmission to near-new condition.
* Transmission replacement: If the damage is too extensive, a replacement transmission might be the most cost-effective solution. You can use a rebuilt or used transmission, which is typically cheaper than a new one.
3. Choosing a Repair Shop:
* Specialize in transmissions: Find a shop that focuses on automatic transmission repair. They'll have the expertise and tools needed.
* Check reviews and reputation: Look for shops with positive online reviews and a good reputation for honest and reliable service.
* Get multiple quotes: Get quotes from at least two or three different shops to compare prices and services.
Important Considerations:
* Cost: Transmission repair can be very expensive, ranging from a few hundred dollars (for a simple fluid change) to thousands of dollars (for a rebuild or replacement).
* Warranty: Ask about warranties on repairs and replacement parts.
* Time: Transmission repairs can take several days or even weeks, depending on the complexity of the problem and the shop's workload.
In short, don't try to fix your transmission yourself unless you have extensive experience working on automatic transmissions. Get a professional diagnosis and let them handle the repair. The cost of a proper repair is far less than the cost of making the problem worse through improper DIY attempts.
