Transmission replacement instructions please?

Hi,

They are both the 5R55S, but chances are there are differences in how the vehicle will communicate with it. Actually, I looked up part numbers and they differ based on production date. You need to get one specific to your vehicle. I suspect the correct transmission will be based on the production date and the VIN. Today's cars have so many modules, sensors, and so on, I swear they change them every year. THis video will help walk you through the repair on a similar car the process is the same.

I don't know if you need them, but here are directions for the removal and replacement of the transmission. The attached pics correlate with the directions.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they can experience slightly different upshifts (either soft or firm) and that this is a temporary condition and will eventually return to normal operating condition.

NOTE: If transmission disassembly or installation of a new transmission is necessary, drain the transmission fluid. Install the transmission fluid pan drain plug when finished.

NOTE: If the transmission is to be removed for an extended period of time, support the engine with a safety stand and a wood block.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Vehicle Jacking and Lifting.

2. Disconnect the battery ground cable. For additional information, refer to Battery.
