No 1st gear

[fastback4]

1997 Monte Carlo LS auto 190,000 mi.
Did a voltage check at the EGR valve electrical lead and accidently shorted 2 wires. Blew the PCM fuse, replaced fuse, now i have no first gear. Has reverse. Car accelerates in second, will shift to 3rd and then overdrive. Fluid is normal. Any suggestions to check?......Tom

see if you actually killed the shift solenoid(or its wiring) that deals with 1st?

Where is the 1 gear shift solenoid located and can I test it with a volt meter?

Whew! I disconnected the battery overnight, reconnected this morning and trans is shifting well. I suppose this reset the PCM thingy doodle brain box ect. ect. ect

yes it did. may have gotten a little power to the ecm just before the fuses blew. sounds like you did a type of re-flash for the tranny. it's amazing how computers work and how a little accident can make one little thing not work.
