Ok let me start by telling you this car was a gift, i do not know its history. As many 94 Accords the car had a hard shift problem mostly going into 2nd gear. I been driving this car for 2 weeks now. There are no codes when i jump the tester, All four gears work and it down shifts fairly well. Normally the car shifts at 2500 rpms. I notices the throttle cable was very loose so i tightened it and that seemed to help a little with the response. The throttle control cable lever (to the tranny) is all rusted but it seems to be moving evenly with the throttle. When i test the throttle control lever by opening it fully by hand, it does not return all the way back down without me pushing it with my hand , but with normal driving conditions the lever is never fully open so it needs to be replaced but im not sure if its the cause of my immediate problem.. Transmission fluid was disgusting, I took the risk and did a drain and fill today with Honda atf. The car now shifts much smoother, I cant even feel 3rd or 4th gear shift. BUT now it has slipped a few times coming off of a turn or from slowing down and accelerating again. It does NOT slip starting from a stop only when i was driving fast and slowed down then try to push the gas. I have to accelerate very slow to have it catch up. I know i did this by taking away the friction pieces with the atf change. Will the tranny get used to the new fluid?? Why doesnt it slip starting off?? Maybe it down shifts into the wrong gear? Could it be the control cable or silinoids?... Any help would be greatly appreciated.
