1987 bronco 5.0 automatic

i am having alot of trouble with my truck recently. Up first is when ever i put the vehical in gear the truck stalls, the rpms go from an idol of 1000 rpms to 100 rpms as soon as i change gears. the truck runs slightly ruff at idol but after i give it some gas it smooths out. any ideas on this?

Re: 1987 bronco 5.0 automatic

what transmission is in your bronco?
ive just started messing with the broncos so im not up on all the possible engine/tranny combos but if you have an e4od theres an electrical connector on the passenger side of the tranny (towards the back of it) that apparently has something to do with torque converter lockup. disconnect this and try putting it in gear. if it doesnt stall you found your problem. DONT DRIVE IT LIKE THIS, just see if it cures the stalling.
