Where is the trans axle throttle cable located on a 2001 Dodge Grand Caravan?

The throttle cable on a 2001 Dodge Grand Caravan with a transaxle (automatic transmission) doesn't directly connect to the transaxle itself. Instead, it connects to the throttle body on the engine. From there, the engine's power is transferred to the transaxle.

You'll find the throttle cable routed from the throttle pedal assembly (inside the vehicle, under the dashboard) to the throttle body. The throttle body is located on the engine, typically near the air intake. It's a relatively large component with a butterfly valve inside. The cable is attached to a linkage or lever on the throttle body.

To be absolutely certain of its location, you'll need to consult a repair manual specific to your 2001 Dodge Grand Caravan's engine (it could be a 3.3L, 3.8L, or possibly a different engine). A diagram in that manual will precisely show the throttle cable's routing.
