- 894
So the Trans-go kit has been installed, and the truck has been fantastic for the past 4k miles since then. Well, yesterday after a drive around in the city to take care of some errands. I noticed the truck was acting erratically. 1-2 was a harsh again, and 3-4 could be felt like 1-2. Putting it in D or R results in a harsh shift that slightly lurches the truck forward or back. I left it sitting for a bit, and ran out again to the store and it was shifting fine as it did before without any issues at all like nothing ever happened. Fast forward to today, I'm on the highway driving home from work and the CEL kicks in. I'm about 2 mins from home when I exit the freeway, and pull up to a stop light. Harsh shifting again.
Torque is reading a P0700 as the first, and a P0894 as the second. Tranny fluid still looks nice and red, and fresh. Nothing particle wise on the dipstick either or any kind of burning smell.
Any ideas on what it could be? From what I can see, I still have all gears. It just shifts harshly into each one. Restarting the truck seems to temporarily fix it.
Edit:
I tried searching around various forums as well as here, there seems to be a mention of the Transmission Control Solenoid. From what I'm seeing on the 4L60E wiring diagram in the service manuals, it seems to be part of the wiring harness that runs along the valve body. After doing some searching on RA, it looks like AC Delco makes a replacement (Part # 214-1892).
