My 93 started to have p076 code, trans pressure solenoid. Read some posts and some people with problem said it could be pcm going bad. Change pcm and code p076 went away but started to have stalling problem but no codes. So I can switch pcm's back and and get old codes p076 back. Switch back to other pcm and get stalling back. These were rebuilt pcm's. Any help would be appreciated, thanks.
