Did you confirm you have all fuses in the correct spots / plugged in properly? Some fuse boxes have blanks you can accidentally plug into.

Did the car drive before you decided to replace the fuses and relay's...If so it's something you touched or did.

Car ran perfect...thought it was something I did,but after researching, not so sure
I checked all fuse and relays ..all in correct locations..and pulled them again and tested every one..all good....apparently there is a solenoid pack in transmission that can fail...?

[2005BlackGT]

Yes...all in correct locations and all test ok

Those transmissions are horrible, you can start with the solenoid pack which is a bitch to change and hope for the best. Mine ended up being the Torque converter. This is assuming everything else you touched is OK.
