Check the fuses within the Ebox. Once you open the Ebox you'll find a cluster of fuses. I'm sure you'll find one of them blown. If you find a blown fuse, remove the thermostat connector and make sure it's not melted. If it is, repair it.

Good luck!

Punctuation is very important, if you want to be understood.
The 5hp30 might have a different transmission control module VS the 5hp24. It's not about the wiring only. That module needs to be aligned with engine control module, EWS, ABS, etc. If you have lite the gear indicator only a couple seconds, you have a power source issue or a transmission control module/can bus issue.
