Transmossion problem on a1998 chevy ck1500 with a 4.3l vortek, 4l

I have a 1998 chevy ck1500 with a 4.3l vortek and 4l60e trans. Driving to work one morning the trans acted like it popped into neutral, when I got below 50mph it went into third and stayed there. I could manually get second and reverse but no first or fourth. Also the check engine light went on. If I shut the truck off then restart it drives normal for a few hundred miles then it happens again. I checked the code and it came up "shift solenoid B electrical circuit". I replaced both A and B solenoids and it still does it every couple of hundred miles. took it to a trans shop and they think it might be the computer but not sure.

Only diagnostic procedures will find the exact cause. Unless you have the info and the tools to perform this your going to have to have a shop perform this for you.
Guessing only works if your always lucky when you go to Vegas.

Will a transmission from a1998 Chevy Suburban 4x4 fit a 1997 Chevy 4x4 1500?

Check the trans serial/ model numbers to get better info. The only changes could be the gearing ratio's for different models. Go online to one of the bigger 4X4 owners forums and see if its answered there.

1997 chevy 2500 4wd new push button switch new transfer case motor will not go into 4 lo

Are putting the vehicle into 4H then shifting the trans into neutral then pushing the 4L button? If so there may be a controler behind the dash. I can't remember on a 97 for sure but I am almost certain there is a control module behind the dassh switch.

2000 Jeep Cherokee 2WD, 4.0 w/ 4 sp trans. While driving one day we noticed we were in 3rd when the trans was in O/D. I left it in 3rd till we got home. After looking it over and could not find anything I...

Sounds like it could be the connection of the shifting solenoid(s) in the transmission. The are attached to the shifting assembly in the tranny itself accessible once the pan is removed (and oil drained of course). These solenoids are on or off work or do not. they are powered electronically so a bad connection could be a culprit, however it is not uncommon for a wire to become disconnected and then burn the terminals off them.. not a big deal for a backyard mechanic, as long as you plan the oil could make it messy...
Best regards

94' blazer will not strart just died one day while driving it .i replaced fuel pump,fuel filter,fuel ragulater, if you spray starting fluid in it it will start but then die whin the starting fluid burns...

check to make sure they sold you the right fuel pump. they are two pumps for a 4.3 ones a vortek and one is a throtlle body. the eighth digit of the vin will tell you one is a vin w and one is a vin z. the throtlle body only puts out about 11psi of pressure and the vortek puts out about 60psi of pressure.if you put the throttle body pump in a vortek engine there is not enough fuel pressure to run it.
