The GM 4L60E/65E/70E-4L80E/85E Diagnostic Code Book
could be useful while waiting..

I know what the codes are just not sure why I’m getting them when the parts for the codes have been replaced. This is the first time I have dove into trans repairs and they are frustrating to say the least.

The book is loaded with diagnostics.... Was the first thing I bought when even playing with the idea of messing with my transmission.
Now I see it's floating around...arrggh..
Still a good investment..

You have to find out what's wrong. Did you buy OEM and/or Rostra harness and OEM solenoids? If not OEM or Rostra, they can also be no good. Test all new solenoids out of the box to catch defective ones before installing them. If you installed quality parts, cleared the codes and they are re-setting then problem is elsewhere. Keep looking until you find it. I know it's frustrsting but you need to keep at it...

They were Rostra parts and had to drive a town over to get them. Pulling it all apart again today to check everything again. Hopefully I can find the gremlin.

Tore everything back apart. Checked all solenoids and the wiring harness. Put everything back together, cleared codes test drove and no change. Now along with the original codes it’s throwing code 12. Not sure how the distributor would fit into this equation but seems like the more we fix the more codes pop up

Never mind. No new code. 12 always flashes. This thing has fried my brain….

12 is not technically a code. It will begin and end with 12 always. The codes are after 12 finishes flashing at the beginning 3 times.

Transmission control solenoid end crumbled. Replaced it, new harness, new shift solenoid . Now no reverse at all. It literally gets worse with every new part
