I am new to this forum but not to cars in general. I have gone through the site for quite a while but can't find the info I'm looking for. I picked up an 88 Accord Lxi 4dr auto with 113k on it for my son for college this fall. I have gone through and replaced all the front end bushings/bearings, upper and lower control arms, new ball joints, brakes front and rear, along with the drums and rotors, new plugs/wires/cap/rotor, changed oil/filter and trans fluid.
My issue is while driving, it will shift from 4th to 3rd at the slightest release of the gas pedal no matter what speed I am at. I can keep pressing the pedal and it will stay in 4th gear but when I get too far over the speed limit I have to back it off a little and it will shift down to 3rd. Is this normal for the car or is there some checks or tests I can do to see where the actual problem is? Any help is appreciated.
