"O/D off" flashing w O/D ON!

Hey there Yota fans,

I just joined the club recently and I'm noticing 99% of the time, the auto trans is skipping 2nd, and going straight from 1st to 3rd. I'm hoping it's something simple, like a O/D sensor. Anyone have any experience with this??? I thought I might change the tranny fluid and filter, but was told by someone else that I'd be better off diagnosing this problem before changing the fluid, as a tranny with 199,000 mi might start slipping with the introduation of clean fluid. I can't verify the miles on the motor or tranny, but the engine is quite tight and runs very strong, like that of an engine that's been rebuilt possibly.

The tranny will jump 2nd with it cold OR warm, and it's got me slightly worried. I'd like to go off-roading, but I don't see that being a good idea without 2nd gear.

I'd graciously appreciate any help or suggestions!

I've been doing alot of reading and I've yet to find anyhting that helps, but I did notice saturday it shifted like it's suppose to for a while, going into 2nd and shifting into 3rd, but it didn't last too very long,... soOoOoooo not sure where to go from here. I may end up looking to a rebuilt transmission. The fluid is nice and red, doesn't smell burnt at all. Fluid level is spot on, so not sure yet what to do. Was hoping it might be something simple, like dirty sensor contacts, but to my understanding, the 2 sensors for the tranmission are INSIDE it, not on the outside.

Anyone??? Anyone???


Bueller??????

Bueller????

Valve body???

After some thought, I'm wondering if the valve body could be the issue... it'd be a much cheaper place to start.


ANYONE?????????
 
Why ask why???

Crazy thing...

Today, it shifted fine on the way to work, at lunch, on the way home.

I'm not about to ask.... :confused:

At the very least I think it might mean it IS a sticking valve in the valve body. Who knows.

There was NO flashing 'O/D off', and it felt so good to have 2nd gear all day today.

Not sure if it IS a stickiy valve body valve if it would flash the O/D off indicator, but I'll see if I can find out more.

I may try and call a toyota mechanic friend in St Louis and see what he may have to say about it.
