first what i have......
92 accord ex with the ha motor and automatic trans.

now the problem.....
car feels like it taking off in overdrive.

examples of what its doing......
i can take off by manually putting the shifter in low 1 and it feels like low 1, i shift to low 2 and it feels like it jumped straight to overdrive.

if i take off in d4 it does not shift and feels like its slipping sort a speak.

what i have replaced to try and fix the problem......
ecu was burnt in the board so i replaced it.
shift and lock up sensor has been replaced.
tcu has been checked over completely and appears to be in working order.
made sure the trans vent wasnt clogged

i use this car as a dirt track racing car.
so there is no dash at all in it now.

raced it for the first time and it was working great. loaded it up and brought it home, everything was fine.
second time out on the track , i have the problem listed above?

anyone know what it could be. im completely lost on where to go next , other than replace the auto with a 5 speed.

 

Check the speed sensors? Not just the vss, but also the mc and nc.

 

Are you still using the factory gauge cluster? Are the D1-D4 lights still functional? This is the only realiable way to check the TCU codes.
