Where is the shift solenoid located? Is it the one at the back of the trans? on 1992 Chevrolet S10

It shifts, but winds out much too long. No codes detected that I know of. I suspect the shift solenoid. Any other suggestions? Thanks!

I don't think this is new enough to actually have a code for this. so yes I do believe this is the location.
