Have DTC P0746 PRESSURE CONTROL SOLENOID ”A”

I got DTC P0746 for DTC P0746 PRESSURE CONTROL SOLENOID ”A”
PERFORMANCE (SHIFT SOLENOID VALVE SL1)
http://tijil.org/Scion_Docs/05_tC_Sh...29/cip0746.pdf

on my 2007 Rav4 V6 with 110,000 miles on it. The Rav was shifting and slipping so bad, it is basically undriveable after it gets warm.I did a lot of research cause I don't have $5000 for a new transmission and found that the solenoid wasn't THAT hard to locate and test. So I opened the transmission, and the solenoid is not clicking with a 9V battery attached (and the otehr solenoids are clicking with the same voltage). So, I verified the DTC, it is bad.

Here's my problem, I can't locate the part number anywhere on any OEM parts website or even the local parts guys are "maybe its this, maybe its that, doesn't match my diagram" runaround. Its shift solenoid 1... it can't be that hard to the part number, but I can't find it.

There is a number on the solenoid itself 1132 CJ136, but that isn;t a toyota number and a google search reveals nothing on that number. Help! I need to order this part asap, as I am without my Rav.

Thanks guy! Love you all!

Mark

That number on the solenoid is probably an Aisin number. Aisin makes the transmission and they have a rebuild facility in Michigan I believe.

That solenoiod is pulse width modulated so your test may not be accurate, too late now but a full scan can command the solenoid on to check it's function. How is the trans general condition after the slipping, fluid burnt? Can't get this from Toyota?

You can't test it assembled unless you have the Toyota handheld computer "Intelligent Tester", the repair guide has you do that, but then also says to do resistance test (it passed this) and the applied voltage test (failed this - this was the only solenoid that didn't pass that test). Fluid does have an unusual smell, but not too burnt of a smell. I wonder why it has a smell, though. Everything inside was clean when the valve body came out, no metal pieces anywhere in the pan or fluid (I strained it). There was a small mound of what seemed to be clutch dust on the magnet, about 1cm tall mound. I don't know how much dirt on the magnet is normal for 110,000 miles.

I should have the part friday, it was 35210-33020.

Excellent, I hope this solenoid solves your problem. How did you track down the part number?

I found that teardown picture by googling "U151E solenoid"
I got this sonnax ID guide Sonnax - Aftermarket replacement transmission, torque converter, and high performance automotive parts
which specifically mentions "SL1 is a clutch control solenoid and is also known as Pressure Control Solenoid "A"."

Pressure Control Solenoid "A" AND SL1 is what the repair guide for P0746 states.

So, I have the location in a guide from sonnax, and I found the teardown picture with the toyota part numbers from this picture
(by googling U151E solenoid and looking at google images)...
Then I matched the 35210 parts number to toyotapartszone.com
http://www.toyotapartszone.com/Page_...ponentsIndex=9
For Toyota parts its called "SOLENOID ASSY, CLUTCH CONTROL, NO.1"

So what is it?
1. Pressure Control Solenoid "A" (repair guide)
2. Shift Solenoid Valve SL1 (repair guide)
3. SL1 (sonnax)
4. SOLENOID ASSY, CLUTCH CONTROL, NO.1 (Toyota parts database)

It's ALL of them... no wonder the parts guys on the phone were VERY confused. I got quoted $480 from one of them... lol...
of course default to charge me the most $ and they can't go wrong ordering any of them



Not at all easy. Now I know what mechanics and parts guys can sometimes go through.

Another thing.. didn't websites like sparks toyota used to have parts number and now they don't ? They're losing business this way. I need to confirm part numbers and will shop at the sites that have the part numbers listed, like toyotapartszone.com. trdsparks.com needs to list the parts numbers. What do you guys think?

Agreed, but most dealers are pretty independent and feel they don't have to be competitive, I get shop discounts here but the local Toyota dealer will only give us 5% off!! Btw I have used Sonnax before and there info is a-one!!

Well, it was more than the solenoid. After replacing the solenoid it still had issues. It is being rebuilt now at a local shop Anyone know the quality of Raybestos clutch packs? Is there a Japanese brand rebuild kit for the Aisin U151 transmission in my 2007 Rav4 V6?
