I've read just about most of the post this evening, and have tried some of the answers. I bought a 97 blazer from my sister. My brother in law changed the fluid and filter prior to this problem, or so I'm told. I dropped the pan and replaced the filter and fluid on the chance he put the wrong fluid in it, and have did the Battery Disconnect trick, then took it for a spin for the first time. Fluid is at correct level, no drips or runs. I start out with it feeling like it's driving through syrup, like I'm giving it more gas than needed to go. It will shift from first to second, but when it feels like it's shifting from second to third, it's like I shifted into neutral. (side note; while the pan was off, I did some looking around. I pulled the clip from the 1st/4th solenoid, and a white looking plunger pushed the solenoid out of the hole it was in. I reinserted it and replaced the clip. Upon removing the clip from the 2nd/3rd solenoid, there was no plnger and I had to pull it out of the hole it was in manually. I reinserted it back in and replace that clip. I visually looked at, and physically felt each wire to make sure none of them were nicked or cut. I plan on calling a Mason Brother who is a Service Manager at a Chevy Dealer tomorrow or Monday, so IF I get any answers from him, I'll post them too...

Can some one tell me an easy way to tell if a 97 blazer transmission will fit my son's 1998, both trucks are 4x4. Thanks in advance.

Check for vacuum leaks! Just had the same problem in my 2000 blazer. Other than that it is probably the vacuum actuator.

I have a 97 S-10 Blazer. Sometimes it will not start like it is not in Park. After many tries of wiggling the gear shift and such, then it will start and run fine. Anyone have any ideas about how to fix this.

I'm having the same problem a few of you have discussed here. I have a 96 Blazer 4wd and when I got it at auction and drove it home it shifted OK albeit a little hard from 1st to 2nd. When the vehicle reached operating temperature though, the check engine light came on and it wouldn't downshift to first or shift into overdrive. It would start out in 3rd unless I manually downshifted, and even then it would only downshift to 2nd. I un-hooked the battery for 15 min or so, hooked it back up and the problem went away a few minutes only to trip the check engine light again, and shift goofy again. I have seen replies of "change the fluid and filter" a lot and have yet to do it. I guess what I'm asking is if anyone that has had this exact problem (I've read several instances of it here) changed the fluid and it fix the problem? I know its one of those things to narrow it down, but I want to know if changing the fluid with this particular problem has ever fixed it instead of only ruling it out as a possible cause. So.. that said, what should I do, I am mechanically inclined, I was a certified mechanic at one time (not in transmissions though) and have a few tools. Any help you can provide would be greatly appreciated!! Thanks!

I have a 96 GMC jimmy, which had the same problem. A friend of mine which worked at a chevrolet dealer did some research and and said that we needed tio replace the wire harness going to transmision. We did and I have not had a problem with it going on 5 years now. the wire harness develops some kind of voltage drop and keeps it from down shifting

Was your problem exactly like mine? I want to be sure before I take drastic steps in what could be the wrong direction. I only ask because others have stated they have the EXACT same problem I do.. I just want to be certain.

I'm pretty sure it is. My check engine light came on and when ever i came to a stop and restated it would start out in like second or third gear, would not down shift to first. also there was no passing gear. At that time i took it in and had the transmission rebuilt. on the way home from picking it up it did the same thing .check engine light back on and no first gear. $1200.00 dollars down the drain. All I can say is when we replaced the wire harnes and pigtail going to transmision my problem went away and has not been back since.
