I'm Awesome
Hi all,
I recently swapped out the harness and solenoids (solenoid kit) on my 4L80E.
After swapping it out it shifted terribly hard in all gears, but as I had checked the fluid level in the dark, I later found out the fluid level was way too high.
After removing excess fluid and sitting at the correct level, I took it for a run a few times and it ran like a dream, shifting perfectly in all gears.
Today I drove it out the driveway and it began holding 1st for a really long time and then a firm shunt into second. All other gears seems perfect and otherwise runs fine. I'lm not seeing any codes.
I've done a bit of a search on various forums but not quite the same problems occurring as mine. I'm not seing any CEL but I'll scan it anyway. Has anyone had a similar issue after swapping out their solenoids and is there some learn procedure I'm missing?
Cheers.
