Like so many others, my 92 Accord AT shifts harshly. I've been on a quest to find the reason why for awhile now and I just read in the DIY section that the transmission throttle cable may be to blame. The shifts are smoother when more throttle is applied. This sounds like a really simple fix. Does anyone have any experience adjusting the transmission throttle cable? Is it in an accessible place? I would really appreciate a little more detail on the procedure before I give it a try. Thanks!

 

if you look at your throttle body you will see either 2 or three cables attached to it. one is for the throttle, one is for the throttle sensor on the transmission, and the third is for cruise control, if you have it.

I believe that the tranny throttle is attached on the passenger side of the throttle body, wheras the other cables are on the drivers side. Follow that cable down to the transmission. There is the linkage. Im not really sure how you would shorten this, though, and I wouldnt recommend it as the transmission allows the revs to go higher when you give it more gas, so you might screw up when it shifts.

 

Just a little piece of logic for you.
You car should probably shift smoother at 3500 than at 2000.
Here's why:

When accelerating from 0-10 you get there faster then you can get from 10-20

Like going from 60-70 or 100-110.

So basically what I'm saying is that your car's acceleration rate is actually decreasing. That extra few milliseconds is enough to make it feel smoother.

Don't really know if you know what I'm saying, but I'd mark the location of everything before you start that way you can go back.
Let us know how that works out. I can't say for sure it is the same on every vehicle.

 

You can try adhusting the cable,, you will need 2 , 12 mm open end wrenches. at the throttle cable at the tranny there are 2 nuts, ( 12 mm ) loosen the bottom nut enough so you can turn the top nut , the top nut is the actual adjustment nut .

if you want a smoother shift , you got to make the cable longer , so loosen the top nut ( counterclock) turn the nut only about 1/4 turn at a time,, adjustment is very sensitive , then lock up the lower nut make sure that the top nut does not turn

you might have to adjust it a few times till you get ti right

another way is. that you can sync the lever.. start the engine and let it get warm , fans come on, have someone accell the car ( neutral or park of course) , while you watch the throttle cable at tranny, as soon as rpm start to go up, the throttle lever should star to move ( in sync with rpm ) than adjust accordingly
