I have a 97 Blazer 4x4 - 4.3 w/4L60e.

On my way to KOTS Saturday I noticed when I got off the tollway that when pulling away from stops under normal acceleration, the 1-2 and 2-3 shifts were delayed and very hard, almost like it had a shift kit. We stopped for lunch for half hour, and when we left it was shifting normal (I assume because of a cooldown period). A couple miles down the road, after getting back up to operaring temperature it started doing it again. Eventually I got a SES, but I periodically get one for O2 sensor, so I'm not sure if it's related. On the way home it did the same. Later on I stopped for a hour or so, then drove home about 12 miles. SES cleared and it shifted normal all the way home.

Yesterday and today I drove the truck and no problems, but I didn't go far.

Any ideas?

It has around 125k. I'm not sure of the service records since I've only owned it for just under 2 years.

I'm thinking it's more of an electronic problem than mechanical since the shifting is electronically controlled by the pcm.

Yes Blazer racing season starts in a month or so lol.

I did a search on the Blazer forums and it's looking like it may be the TPS.

Sounds like the trans is on its way out. We use to have a caravan and those where the first signs of when the trans took a shit.
