I replaced my vehicle listed above's transmission and I got the gearbox error. When I go to shift it doesn't register or move. Do I have to change to the old value body or reprogram it?

Hi,

If the fluid is full and there is no response, it could be related to the range sensor/park selector switch. However, it is integral to the shift lock solenoid and shouldn't have been touched.

When you shift through the gears, does the gear indicator show the correct gear? If it doesn't, we need to scan the can-bus to see what codes are stored.

Here is a link that explains how to do it:

Let me know. Also, let me know if the transmission is used or new. I reviewed the manual for replacing it, and there is nothing indicating reprogramming requirements.

Take care,

Joe

What was the code that was retrieved? Also, does the gear indicator work inside the vehicle?

Let me know.

Okay, update I changed valve body and it moves now but 3rd gear it won't shift unless its redlined. But if I do the manual shift it goes through the gears, no problem.

Hi,

That's a step in the right direction. Are there still codes stored? If so, let me know what they are. Before you indicated the scan tool showed "transmission locked." Let me know the actual code.

Take care,

Joe
