Hello I have a problem with my 1992 Accord Coupe :

The 'S' light is permanently on and the automatic transmission isn't changing gear.I can manually change gear but I only get 2nd and 4th.I have tried linking out the service connector to get a fault code , and the engine warning light comes on.

Where do I begin?

 

Ever changed the transmission fluid? Does it shift gears hard?

 

I have removed the Auto Trans control unit and found 2 resistors blown within,The resistors are R42 and R41.Honda want £550 ($1066) for a new unit,,,i think i will have to find out somehow the values of the resistors and change them,or get a second hand unit....

 

I removed the Automatic Transmission Control Unit(situated passengers side under the carpet,,use a 10mm deep socket the remove plate) and found that resistor 41 + 42 had blown just like this persons:

I have tried replacing the resistors with 500ohms but it didnt work,then i linked them out with just wire and everything came back to life.I will have to play around until i get the correct values for the resistors because i dont want to leave just wires coz it may cause other problems.

So Honda wanted £550 for a new unit and they were out of stock
The scrappy wanted £60
I fixed mine for nothing :O))))

 

If you need to find out the resistor value try this site Calculate Resistor Values .

All you need to do is enter the band colours and you'll get your £550 honda fix for a couple of quid. Let us know how you get on
