now thats its getting in the 40s and 30s. sometimeswhen it goes to shift into second itll go back to first then back to second. Then yesterday while in any gear even reverse the converter would lock up with the trottle input over 1/4 throttle. That shouldn't happen because it was 35 degrees outside, vehicle speed was 5 mph,and i wasn't in 4 gear. any help thanks.
