so i have a bad solenoid in my tranny that controls my 1st and 2nd gear, i have a replacment but i need to know which solenoid i actually need to take out, ive seen the picture of the valve body with all the differnt solenoids but i dont remember where i have seen it if anyone can post a link so i can check it out that would be greatly appreciated! Oh the tranny is a A340H automatic out of a 93 4runner
THANKS!

 

The FSM should be good enough to guide you through the process. Here's the automatic transmission section.

You might want to consider replacing all of them while you have it apart. If one's going bad, the others won't be far behind.

 

Shift solenoids 1 and 2 work together in a pair. 1 on, 2 off is 1st, 1 off 2 on is second, both on is 3rd and both off is OD. So if one is not working, you would have two gears messing up.
