Default AOD Trans won't shift

My AOD trans won't shift out of first!! I'll put it in Overdrive and drive but it won't shift. If I get up to about 25-30 then it will just rev up as if it is in nuetral until it hits a high RPM then grab as if it's still in first gear. The trans was just rebuilt about 2 years ago. And for the smart asses like Adder...yes I checked the fluid. It's good and doesn't smell burnt.

Could a bad filter cause this??! I'm hoping it's something simple, but with my luck it won't be.

the problem sounds like a speed sensor on the trans. check your connectors for corrosion, and check for a broken wire.

AOD's have throttle valves. They MUST be adjusted appropriately in order for the AOD to shift. (This does NOT apply to the AOD-E). There should be a throttle valve cable attached at the TB or carb. It too tight, you gotta pop the locking clip out and adjust it. Ill see if I can find some info for you.

Ok I found the article on another forum I go to.
http://www.rangerpowersports.com/for...d.php?t=137652
This will tell you what and how to adjust in order to get your AOD shifting. Hope this helps.

Default RE: AOD Trans won't shift

I tried a few things and heres what I figured out...

It's shifts hard in to rev. and drive
If I'm going down the road, let off the gas and shift it back and forth from "N" to "D" about 10 times then back into "OD" it will shift. Almost like the cable is sticking and moving it back and forth frees it up somehow.

Theres a couple of things for you guys to kick around...by the way, if anyone is interested, it just came up on the market. Just found out we have a new baby on the way and it's time to let someone that has the money fix it up.

Yes it's in there. I've had that happen in the past so I have several extra grometsin the glovebox. I'm starting to get the feeling it's internal.

I had the same problem with my AOD and foundout that the jackshaft was broken. I would check the TV cable first because it seems that it has to be perfectly set for the trans. to shift right.

Been messing with it a little more and come to find out, if I just put it in nuetral while I'm coasting and let the RPMs settle, it shifts. How much was it to get that jackshaft fixed??

Default RE: AOD Trans won't shift

I had an AOD once in a truck, kinda done the same thing as yours. They have the govenor in the tail part of the tranny. Run it up to about 30-35mph and throw it into reverse and then back into drive. This shocks the governor valve and will free any trash that might be in the govenor body. It can be done on jack stands if you fell like jacking it up. I know it sounds like a crack head idea, but I had a mechanic show me in my own vehicle. And it did do what he said, when I left his shop, the old tranny hit all 4 gears as it was meant to be.

Mine was on an 83 model truck. Maybe thats why I didn't have the shut off problem.
