I have a 98 explorer with the 4r70w trans. everything seems to work fine except second gear. When it shifts from first to second it will go to shift hesitate then shift . Its like it has a slight hesitation there is no slipping and all the other gears do just fine, Also sometimes it will shudder in second gear like the t.q. is stating locked ehen it shouldnt. Also if you sit there and put your foot on the brake and shift through the gears when you put it in second it stalls because the t.q. stays locked. This is what I have done so far changed all fluid and filter. Flushed it with a 5 gallon bucket letting it drain into out of transmission cooler line until fresh fluid comes out. Then put some friction modifier in it didnt put whole bottle in but starting to think I should. Does anyone think it might be the t.c.c solenoid or other ideas. Just feel like it isnt the tranny has to be a sensor or something since it is just second gear and none is slipping.
