Wiring diagram for a 86 22R Automatic Pickup

I'm trying to diagnose a problem with my Overdrive on my 86 Toyota pickup
with a 22R, and of course automatic transmission. I solved two problems
with the system already. First the wires connecting the shifter switch were
cut. No problem rewired the switch. Then replaced the bulbs in the
Overdrive light. Now the switch activates the Overdrive light but not the
Overdrive itself.

So I'm trying to find a wiring diagram, online if possible to find out where
it actually activates the Overdrive. Can anyone help? Should I be looking
at the transmission or the distributor?

TIA,

JW

BEFORE......you go doing anything else, do this.............

There is an OD solenoid on the drivers side of the transmission.
It will be the only bolt on thing with wires going to it, just above
the pan, located about mid section of the trannies body.

Unbolt it......take it out.....then take off the o-ring that's on the
end of
it. Bolt it back up and go for a test drive.

If you now have OD, you can either concern yerself with repairing
the evident wiring problem or bad OD solenoid.

or..........
you could just go about yer merry little way and live with the fact
that you now have OD but not the function of cancelling it out.


If OD doesn't work after removing that o-ring, you've got a bigger
problem than wiring or solenoid. The problem will be internal of
the unit, or a plugged up solenoid passage.

Fact, not fiction.

do a repost.....
let us know.

Thanks, I found a 85 shop manual and found what I was looking for. There
seems to be a way to test the solenoid. It cant be that much to replace, I
had to replace the Reverse light switch on my 93 4Runner before, and that
was not too bad. Right now anything that will get me into OD would be
great, coz I'm only getting 20 miles to the gallon. I'm hoping I don't need
to go into the valve body of the tranny, coz that's the next step if the
Solenoid is OK. I'll keep you updated on what happens.

Thanks again.

Define anything.



The easiest way to get OD is to yank the o-ring off the solenoid.


(maybe i used too many words in my first reply..??..)

Maybe as a last resort, but if the replacing the Solenoid is needed and
within reasonable cost, why not?
