Please I need an advice before I change my gear,
I drive an honda babyboy 1999, Automatic

I notice that when accelerating from a complete stop, the car does not go through the first gear smoothly,the car jerk forward pretty rough before it will enter the second gear. And when once I slow down the car jerk again before it enter gear one and once I accelerate with it jerk before it will enter the second gear.

My mechanic said I need to change the gear.But I believe that should be the last option.

I have scan the car and below is the error code.

P0122 Honda-Throttle Position Sensor/Switch A Circuit Low Input

P1166 Honda - Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction

P1167 Honda - Air/Fuel Ratio Sensor 1 Heater System Malfunction

P0141 Honda - O2 Sensor 1 Sensor 2 Heater Circuit Malfunction Bank

P0700 Honda - Automatic Transmission Fault

P1738 Honda - Problem in 2nd Clutch Pressure Switch Circuit

With the scan codes you have provided a very good transmission specialist would promptly fix you gearbox,

Replacing the clutch pressure switch and throttle position sensor will solve your transmission faults.

The trottle position sensor is on the the throttle body.

I will post pics of the pressure switch later.

For the clutch Pressure switch you can replace and also check your transmission fluid if it gauge and still ok.
On the TPS, it might not actually be the sensor but first clean the throttle body and see if the magic will work. also work on all other code.

You might not need a transmission specialist since the switch is located outside the gear box, but somtimes experience with certain faults makes work easier, so if you know one it might not be a bad idea.

Arrange for a new gear box bro.
