Tranny problem when driving on uphill???

89 Civic has no problem on freeway driving. It's uphill when the
tranny acting out strange. On uphilll driving, sometimes it can't find
the right gear and it still for a quick moment and then suddenly
accerated, but most time the car lost the power and so slow climbing. I
posted this before. They suggested me I should drive a gear with "D2"
or "D3." One time I shifted a gear to
"D2" on uphill driving, and the car was overheating. The RPM was very
high. I guess the high RPM caused the overheating. But my question is
do I have a tranny problem here? Why my car has no
power on uphill driving?

 

With that age of a car you should learn how to become a mechanic or get
rid of it. It's going to need parts replaced on a regular basis to keep
it in good shape.

 

red cloud, the symptoms you describe are typical for that vehicle.
advice you've previously been given is the best possible considering the
transmission/ecu that vehicle has. your only alternative is to buy a 99
or later civic that has "grade logic".

 

then it's normal

 

-------------------------

Are we forgetting the obvious, like, what's the mileage, when did you
last check the tranny fluid level, what color is the fluid on a white
sheet of paper, what kind of fluid are you using, does it smell burnt?

I had an '88 Civic LX (manual transmission) that did the exact same thing
when it was new. I was driving in the hills around a lake in Austin with a
couple of passengers one morning and my car simply wouldn't take some of the
hills. I finally had to turn around and give it up after smelling a burning
odor. Forget it! I was so mad. I asked around and was told the engine was
just too weak. Dunno if that was it or not, but the VTEC in my Accord
handles hills fine.

 

On a flat road, get the car rolling. Then push accelerator
all the way down and keep it there. Notice the rpm when the
transmission up shift. If it's not any where near red line,
the transmission cable need adjustment.
