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.
