Trans acting weird, threw a code. I cranked the car this morning and went to leave like normal. As I pulled out of my driveway, I noticed that the car was stuck in third. I limped it along to where I was going, checked the fluid, it was fine.
Left where I was at, car was still acting up. I had 3rd and 4th, but I only had 2nd if I put it in "2", and didn't have 1st no matter what I did. And it threw a code. I pulled into the local Advance Auto and had them scan it. It was a PO758 code, (Shift Solenoid B Circuit.)
Went to leave again, and voila! the car acts just like normal, just like nothing happened. I gave it a few WOT runs to make sure everything was alright, and it acted normal at WOT too. Reset the PCM and cleared the code. It's been acting right since.
Has anyone else had this happen to them? It seems like (hopefully) it was a one time thing. Or do shift solenoids act up a couple times before they go out?

I have messed with a few LT1 cars that the shift solenoids went out on and new ones fixed the problem! One time I run into one where the shifter cable bracket came lose from the tranny pan and would only stay in second but you gots a code!The shift solenoids are fairly cheap and very easy to put in! If it comes back slap one in it!

Mine used to stick, after the car had sat for awhile. I could start the car then start driving till it warmed up, stopped cut the car off & cut it back on then it would be fine again. I never figured out why it did that. But I replaced both shift solenoids along with the TC lock up solenoid & I never had that problem again. Instead I just burnt up a trans 6 months later. (2 much nitrous)

Guess I'll have to fix it.Where did you get the solenoids, and are they both the same. On all the auto parts stores' sites, I can't find any difference.
I know that the "B" (2-3) Solenoid is on the passenger side. Does anyone have any pictures of just what it looks like?
Vann, how much of a PITA was the replacement?

You just un-plug them then pull the clip that is holding them in out, the pop it out. Replace with the new on & reverse the removal process. All you have to do is remove the pan to get to them.
I'm taking off the extension housing tomorrow to get the bastard out. I left the car up on jackstands for tonight 'cause I'm tired of fighting it.
FWIW, the solenoid went in in about 30 seconds once the pan was down. I'm really glad I put in that drain plug now.

Later!
