When I bought this Bronco the seller told me the transmission has a issue, he wasnt sure if it is toast or just needs "something". The truck moves forward and reverse, drove onto the trailer when I picked it up. Drives around my yard. Last night I decided I was going to take it down to my local gas station and put some fresh gas in it. It started out fine , then it started to act up. It takes off in first ok, then when its time to shift into 2nd ,it just kicks into neutral, there is no 2nd there, if I let off the throttle , it will shift into 2nd, and if I'm real easy on the gas pedal , it will continue on. If i step on the gas pedal I lose 2nd again. I thought it would have the E4OD in it because its a 1989, but it doesnt. I was just under looking at the trans and its a square pan , 14 bolt, so it has to be a AOD or AODE trans. This truck has had a lot of money put into it at some time in its life. A lot of things have been changed , the motor is painted orange (had to of been out) , it has headers on it with duals all the way back , the 3in lift, had all K&N filters(gone), starter looks new, HAD a huge stereo system at one time, Looks as though it had a visor on it. Somebody really cared for this thing at one time , then it got parked. Maybe the dude died who owned it...seen that before. Anyways I think the trans has been changed or maybe it came with it , I'll wait for one of you guys to tell me what was in the 89's. Any idea on the tranny issue would be appreciated.
