Duty solenoid B

[michael]

I'll pull the codes this weekend but I'm pretty sure it will be duty solenoid b. Where abouts do you disconnect the loom from the box? I found one spot on top behind the band adjustment screw. That seems very hard to reach, let alone disconnect and probe. Also will the fact that I have a US box matter as far as wire coloring?

This is usually caused by a problem with the tranny resistor causing a Duty Solenoid "A" failure error (code 11).

With my luck it's both A & B!

What is the resistance supposed to be? You are refering to the one behind the battery, right?

[Earthworm]

Yes. Normally between 7 and 15 ohms. When I replaced mine the new one measured 12 ohms.

You were right Earthworm, I pulled the codes and got eleven. I checked my resistor and it is in fact bad. Now I have to find a resistor somewhere. I can't seem to come up with a 20watt 15 ohm resistor anywhere, I don't want to settle for a 25w but if I have to so be it. Did anyone find a source for 20w resistors? Has there been further experimentation with the resistance?

Ok Harvey as far as mesuring the resistance, i could not locate a green with black on the transmission side, only on the engine side of the loom, it conected to an all green (g) on the plug, i mesured the rsistance between that and the black (b). I set the multi meter to 2000 and got a reading of 24? at 2k it read 0.02.

I then tested all the other points and the closest i came to your required reading was the pin three down two across (top to bottom left to right) which read at 2000, to be 13.6ohms

can you make sense of any of this???


futhermore, I know know what the torque convertr lock up looks loke on the tacho, i seems after a few days of watching that it will lock up on some occassions and not others!

cheers,
Jake

You are better off with a 25 watt resistor, as it will run cooler. An even higher wattage would not go amiss.

The deciding factor is simply the physical size of the animal. The wattage does not effect the performance of the circiut in practice, but if too low it will burn out.
