I have been searching for hours and can not find A/B (1-2,2-3) springs anywhere for 4l60e. Dropped my pan today and went to change the solenoids because 2 to 3 was shifting hard and had no 4th/OD. When I took A solenoid out noticed that the valve was not springing forward like it should. It was getting dark so I left the job there for the night.

I do plan on checking to see if the current spring is just jammed up or if it is broken but thought I’d look around for a replacement if I need it. Only thing that comes up is for 4l80e.

 

Did you find your springs?

If not, what year is your Blazer?

This link might be of help. https://nemigaparts.com/cat_spares/e...olet/54s-t/04/

I would cross reference any part numbers you find at the above link with a source like www.gmpartsgiant.com where you can put in your VIN and then put in the part number you think is correct for your transmission to confirm it is correct. Then if this vendor doesn't have the spring, you will at least have the right part number for looking elsewhere for it.
