No need to yank valve body for that. That code is usually just from one of the shift solenoids - not a given (nothing is with these electronic wonders), but usually. Very easy to swap those out, and even from GM they're under $30. If the truck starts out in 3rd gear and only shifts to overdrive, then it's the 1-2 shift solenoid. If it starts off ok but won't hit 3rd or overdrive, then it's the 3-4.

The P1870 code means the transmission is slipping at highway speeds. If you do some searching here on the Blazer Forum you'll find various causes for that code. In my case it's slipping in overdrive and it has the hard 1-2 shift once the tranny warms up. That points to a worn TCC valve. I got an oversize replacement valve as was recommended by others on the forum. I also bought a TransGo orange box shift kit which I'll install while I have the valve body out.
It sounds like you may have the same issue on your transmission. It might not be a bad idea to investigate further and fix it before it causes a further problem. The 4L60E, when cared for properly, can give a long service life.

Bought this yesterday for my truck. Its off a WJ Grand Cherokee. Looks to be a close fit. Ill be moving the mount brackets this weekend to bolt it on and see what I need to change for it to fit perfectly. For $100 it wasnt a bad buy.

Installed the antenna adapter for the new delco radio... Every thing works... I moved her around and then parked it. I wish I can fix my fuel issues already.
