Speedometer stopped working/not shifting

Hey guys,
I just fixed my 2010 after a fender bender.
I recently changed the radiator/intercooler/battery/etc
Coolant sprayed all under the hood which I believe caused a few electrical issues.
I got most of them sorted after spraying the fusebox with electrical cleaner and it runs fine.
Now my only issue is the car won't shift out of 1st in D and won't shift past 2nd in M mode - the speedometer also isn't working. No codes. Any ideas or connectors I can check/clean. Is there a VSS etc I can check?
Thanks!

Some codes will not show up. A "pro" reader can pick up more codes but its likely.


Do you have a SCZT tuner etc ?

how many miles on your SHO?

would check the connectors at the solenoid body assembly and at the PCM, verify they are clean and tight, put a dab of dielectric grease in there when reassembling.

there should be a fuse for the TCM, check to make sure it is not contaminated.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
