I have a 4wd 4.3 auto tranny with 159k miles. when its cold it runs fine but when it warms up the engine wants to die when its in drive and the brakes are applied. also wants to die when put into park or neutral from drive or reverse and vice versa. it also hesitates and stutters if im not gentle accelerating from a stop. it shifts fine never slips everything works on the freeway its just stopping and accelerating from a stop (kind of important) that has issues. if it does die it starts right back up and i can take off (with a gentle acceleration) tranny fluid as been replaced though there is a slight leak from the transfercase. 4wd works. im trying to avoid replacing the transmission or torque converter but let me know what you know thanks!
