Why it's a good choice:
* Strong & Durable: The TH400 is known for its robust construction and high torque capacity, making it suitable for the increased power output of a V8 engine.
* Performance: Its strong internals and multiple gear ratios provide excellent acceleration and towing capabilities.
What you need to know:
* Modifications: The TH400 is a larger and heavier transmission than the stock S10 transmission, meaning you'll need to make modifications to the transmission tunnel, driveshaft, and possibly the rear axle.
* Adapting: You'll need an adapter plate to mate the TH400 to your V8 engine, as the bolt patterns will likely be different.
* Control: You'll need to install a separate transmission cooler and a proper transmission control system, as the TH400 doesn't have an electronic controller.
* Cost: The TH400 itself, along with the necessary adapters and modifications, can be a significant investment compared to other transmission options.
Alternatives:
* 700R4/4L60E: These are more common and readily available, with automatic transmission control systems and potentially less modification needed.
* 4L80E: This transmission can handle high torque and is electronically controlled, making it a popular choice for V8 swaps.
Before you commit to a TH400:
* Evaluate your budget: Consider the total cost of the transmission, modifications, and installation.
* Research: Thoroughly research the necessary modifications and compatibility issues for your specific S10 and V8 engine combination.
* Seek professional help: Consult with a reputable transmission shop or experienced mechanics for expert advice and assistance with the swap.
In summary, while a TH400 is a strong and capable transmission for a V8 S10, it requires significant modifications and investments. Carefully consider your needs, budget, and the complexities involved before making a decision.
