Just pulled the trans pan off my 80, replaced the fluid strainer and flushed the old fluid out through the cooler mounted near the radiator. Put the pan back on with oem silicone and used Valvoline ATF max life for the fresh fill up. BUT one thing I did not do was replace the shift solenoids. I probably should have. What are your opinions on replacing them before a long road trip? Will I be okay without doing them? I looked heavily for another forum before I posted. (Lesson learned). Couldn’t find one so I’m posting my own. Cheers.
