Ok So on my 1997 Chevy C1500 4.3v6 The transmission isnt ****fing correctly, its from 1->2 and 2->3 I havent gone up all the way to 4. So I was worried and I took it to an auto parts store checked the fluid (fine) and borrowed an OBD scanner and it didnt fire any codes besides a misfire on cylinder 1. Im stumped and dont know whats going on, I just want to get my baby fixed. Any ideas what could be causing this?

 

LOL it blocked out S H I F T I N G.

 

You have an automatic transmission? If so when was the last time you changed the transmission filter?

 

Shoot, probably not for a while, it happened after I let it sit for like a week aswell. If that would help come to any conclusions for you.

 

What model transmission is in the truck turbo 350 or turbo 400?
Was it shifting correctly before it sat for a while?
Have you checked to make sure the modulator valve is holding vacuum?

 

350.
Yes it was shifting perfect before, and what do you mean? Where is the modulator so i can check it?
