I've got a 2000 Rodeo LS V6 3.2. The transmission changes just fine,unroll I drive 50,to 100 miles,then it's reluctant to shift from 1st to 2nd. Goes through all the other gears just fine. The way I get it to shift is,I run it up to 3000 RPMs,and let off the throttle, and it shifts. I've had it serviced,new filter,new fluid, etc. My mechanic says there is no metallic debris on the magnets in the pan,or any other signs of a problem. Oh, also,it's 2 wheel drive.
