o/d drive 4r55e

[f1ipf10p]

i have a '97 ford ranger 2.3L 2wd 4r55e. i can't drive my car in o/d in 1st and 2nd gear but when i get to about 35-40 mph i can engage it again and it works but i have to be careful how hard i touch the gas, to much and the tranny disengages and the engine winds up and i have to wait till it comes back down and slowly press the gas till i hear and feel the tranny catch again
