2001 Rodeo Transmission

2001 Rodeo 4x4 3.2 auto
173,000
I have reverse only, wont go forward. Will not move in any manual mode. Will go in winter mode (start in 3rd gear) only.
Added 1 qt fluid, no change.
Is the transmission shot?

Thanks for any ideas.

try searching or posting at planetisuzoo.com .... I recall it is a solenoid on the tranny that is probably bad.....
