had my tranny rebuilt about two years ago and i cant remember when it started but everytime i drive it, it shifts into second then into 3rd and final drive around 35-40 mph. and when slowing down it doesnt grab first and it almost stalls cuz the tranny's still holding the gear. only happens when the cars cold after it warms up it shifts better. Recently i could feel some slip when acceling from a stop or red light. any suggestions on whats going on? recent repairs include:tranny rebuild 2 yrs, water pump 8 months, alternator 2 months, ignition switch and steering column 1 month, and frnt strut mounts, both ball joints, sway bar bushings and frnt stabilizer bar control link yesterday...about to get rid of this money pit..
