TOZO, Help!
Where did you get the o-ring replacements for the solenoids in the valve body? Are these available at the dealer? Since I am cracking it open tonight, I might as well change them too. Thanks!

My friend has a transmission shop. I found them in a Toyota rebuild kit.
The solenoids don't have any seals. The pressure regulator valves have one. I've used a 2.4mm thick o-ring. I don't think that the o-ring causing limp mode. Do you have any fault codes?

Re: My friend has a transmission shop. I found them in a Toyota rebuild kit.
Yeah I got the error codes stating the gear ratio was incorrect. Can't remember the number off the top of my head. I dropped the oil last night and and will continue tonight. Does the valve body come off easily or are there any special things I should look for when taking it off?

If the car goes into limp mode right after you cleared the codes that is not good.
The valve body comes off easy, but unfortunately your problem is not in the valve body. If your car goes into limp mode in all forward gears, clutch A housing ( 1-2-3-4 gears ) is cracked or it has a blown seal. Do you have a problem with reverse?

I had a same problem last year.
I had a cracked valve body -lost oil pressure to clutch - engine revved up - incorrect gear ratio -tranny vent into limp home mode while it was still at high rpm - BANG - limp mode means, full pressure on clutch A for 4th gear-clutch A housing cracked open. But yours could be different.

Re: I had a same problem last year.
So did you just change out the valve body? I now have my pan off as of tonight. I have more questions about the removal of the valve body. As you know there are at least a couple of dozen torx screws in the bottom of the valve body, which do I remove to take the body off? Do all of the screws come out, if not which ones? I don't want to do anything until I know for sure. Also, is there a gasket between the valve body and the mount or what seals it in place?
Thanks for your insight!

There is no gasket between the V B and the tranny. All the bolts with the big head has to come out.
Leave one on the center for the last, so it will hold it up. It is heavy, so be ready to hold it. There is a speed sensor on the top of the VB. Just pull the two tabs out and disconnect the sensor.

Was it obvious?
You say you had a cracked valve body, were the sign of this obvious? Also, you didn't mention if you replaced the body or did you just replace the whole tranny? What should I look for specifically? I am taking the valve body off this morning.
