Bumping this...

Could really use someone with a lot of sc300 AT experience.

First of all, when you get a code 62, which indicates a bad "number 1 shift solenoid," I was under the impression that is only ONE solenoid. Is this the case?

According to one of those diagrams I listed above there are TWO number one shift solenoids..

And then I called a local dealer (Newport Beach Lexus) and gave them my vin so I could get a straighter answer, he sent me the diagram that came up with my car/vin (mfg 1994, model year 1995) on his computers and I attached it to this comment. This diagram shows two number 1 solenoids and one number 2 solenoids. If this is the case and the diagram is true, does that mean a code 62 requires both number one solenoids to be replaced?

My symptoms:
Code 62 - OD off light flashing while driving.
When my transmission is in -
Drive - 3rd gear and OD (4th)only.
2 - 3rd gear only.
L - 1st gear only.

However, according to this website(http://www.autoshop101.com/forms/h16.pdf), on page 15, the figure illustrates that when only number 1 solenoid is malfunctioning the transmission should still be able to get to 2nd gear while in L

It even says when both are WORKING, in L drive, you have 1st and 2nd gear... Is this true??

That link then states when both number 1 and number 2 solenoids are malfunctioning you will only have 1st gear in L and only 3rd gear in "2" and only 3rd and OD(4th) in "D"

So what could be the case for my trans ??

This seemed like an easy code to tackle, but the more I research it, the more vague the data becomes.

Lock up solenoid and some other solenoid???. I had a hard-time figuring out which solenoids I needed to buy from looking at the real Toyota diagram. They listed three different "shift solenoids" and one lock up. I figured the Rostra kit had it figured out so I went with that. Plus the price. I needed to do this on-the-cheap for a guy.
