I have a 95 civic coupe with a d16z6.the problem is that the auto tranny shifts hard and waits till like red line to shift even when driven soft.if u let off the gas the tranny stays in the same gear so its like drivivg a stick shift car on 2 nd gear to redline and then letting off the gas and u get that whoooo sound.the speedometer isnt working either and i changed the speed sensor but nothing.I was wondering if these cars have a sperate speed modulator or box that tells the transmission when to shift because i had a chevy lumina that had this exact problem and i thought it was the tranny but the problem was a box or modulator that tells the tranny when to shift.sorry for the long post but I dont want to change the tranny if the problem is something else.and the car switches from park to all the other gears fine. thanks

 

you're not running a 5 speed ecu by chance are you?

 

I dont think so.its the same ecu that came with the car when i brought it.

 

sounds like the tranny might just be shot then. either that or you have a blown fuse or something shorted out thats ------- up shift points and killing your speedo.

 

i checked the fuses and there fine.I thought the tranny might have been fucked so i got another one but its been so fucken hot that i was hoping it was something else like what i mentioned above because i didnt feel like sweating bullets under the car.its a good thing I keep a few cars cause Im a lazy bastard when it comes to working in the heat. thanks

 

tranny is probably shot, all that torque being put through the shitty transaxle automatic that hondas are probably fucked up alot of stuff.
