Shift solenoid code

So the transmission place did me a huge favor.

I went there and told them I wanted the solenoids changed and the filter changed. They agreed to do it and told me to come in Monday. I showed Monday, no parts. They asked me to come back Tuesday.

I showed Tuesday, no parts. Please come back tomorrow.

I showed Wednesday, and guess what? No parts.

This annoyed me, so I went to a place and had them read the codes. Yep, the solenoid code had tripped, as had the O2 sensor. The O2 sensor was replaced, the codes cleared, and they haven't come back.

Those incompetent businessmen saved me money.

Thanks for everyone's help on this board.
 
Ah...OK I'm lost. Can someone explain how replacing an O2 sensor (PO420 I assume) fixes a PO770 shift solenoid? Seems coincidental to me.

Hi guys.

I have a 2001 4Runner, 2WD, SR5 with a V6. It has 200,000 miles on it. I had some idiot lights pop up, and the code says it is the shifter solenoid. Should I try to fix that, or is a tranny pretty much ready for replacement at 200K?

Thanks.

Hey dude it happened to my 4runner at 200k and it had nothing to do with the tranny it was actually something to do with the starter lol. Should be all good to be honest reset your battery haha.

Yeah, I just changed my transmission strainer and performed a drain and fill. After that, my tranny once in a great while will not want to downshift. No CEL yet, no pending codes, fluid level is perfect and the same fluid I have always put in. I had the fluid analyzed at Blackstone, and they said it showed no issues, and that my tranny is wearing slower than usual. That's when I talked to my buddy to see if he had a tranny laying around just in case. He did, but it had like 160k on it. He also told me that when you change the fluid, it can make the symptoms worse. He told me that the newer 3rd Gens have a little Higher rate of having issues. Same with the Taco 01-04.

Im just going to drive it until it completely fails, then buy a reman from Toyota and throw it in or convert to a manual tranny.

What fluid did you use? I'm using Valvoline Maxlife in my 6/1996 A340F, but when I do a drain/fill this summer I plan on using either Toyota Type IV or Castrol Transmax Import. My reason is that the Valvoline is thinner than these fluids because it meets Toyota WS standards as well. My transmission is shifting very well considering it has 204k and towed at the rating limit for a lot of its life. Zero slipping, but occasionally I feel like it could shift smoother, but then again no one has ever pointed out a problem so it's just me being OCD as well.

Using Valvoline MaxLife DEX/MERC full synthetic, always have. Compatible with T-IV.
 
Unrelated question.........I am looking into dropping the transmission pan on my 1996 SR5 and replacing the screen and changing the fluid. I have been searching by the transmission model A340E and have found several kits on ebay and amazon that have the screen and gasket. I noticed that a lot of them have a differently shaped screen than the oem version. Is this something I should be concerned with? The OEM screen looks more elongated and in my mind would have a greater surface area for screening.

Here is an example, ignore the solenoids

That's a pretty cheap kit. I don't like the price of it which says to me the parts are cheap too. Get an OEM strainer for sure, if it shifts fine then leave the tranny solenoids alone.

Hypothetically speaking. If someone were to purchase solenoids, would these be of a better quality?

This screen and gasket kit looks more like the OEM to me, but the description talks about some sort of heat expanding material on the initial gasket installation.

Thoughts?

Yeah. I think [MENTION=115590]StreetCreeper[/MENTION] used that kit. When it comes to the strainer, I would only use OEM and Toyota FIPG for transmissions.

Valuable Information

Great Thread.

Had been running with a P0773 code since I acquired this '97 LTD almost a year ago.
Also couldn't shake P0130 & P0133 O2 sensor codes although I replaced the upstream sensor.
Recently she sprung a P0758 Shift Solenoid "B" code.

Gathered some technical Toyota diagnostic information here.

Got oriented with this entertaining video.

Scored the parts as suggested by StreetCreeper on this thread,
...and learned that the job was less difficult than anticipated.

The 100+ miles since the new solenoids and filter have been the longest without a single trouble code (knock-knock).
Could there be "chaos" linking the O2 sensors and the Shift Solenoids?

All I know is my Runner is Running better than ever and I'm grateful to this Forum.

:thanks:
 
Help! This thread still alive?

I have just purchased this kit...

https://shop.advanceautoparts.com/p...rans&utm_campaign=shipped&utm_content=general

and put them in. Before the changeout, the truck would stumble with the same problems mentioned throughout this thread (OD, late/weird shifts, etc.) and now it runs terrible!
Is it possible I could have put a solenoid in the wrong location? How do i know which Is which? There were numbers etched into the back but I don't remember what they were exactly. One solenoid was silver on the back where two others were copper.
Two solenoids were packaged together (the copper ones) so I put those two in the location along the drivers side and the one which was packaged by itsel (the silver one), I put into rear location.

What is going on?!
This thing is undrivable now.
 
Anyone have a source for a sub 150k 01-02 A340F tranny in SoCal? Dropped the pan today to find small slivers of metal, needlebearings perhaps? Changed out the filter and did a drain and fill.... only to have the code for the shift solenoids to come on 75 miles later.

I am unsure for this kit specifically as I have the amazon kit. All of the solenoids looked the same, I had to pull the clips on them and install 2 on a bracket and the 3rd went by itself. They all appeared to be the same solenoid.

What are the symptoms now?

Also, did you bench test your old solenoids? Maybe try bench testing them and/or installing the old ones to see if they conditions change and go back to "normal."
 
So I just did all of the solenoids, filter and fluid. Tranny barely moves at 4K RPM. And goes forward in reverse gear. I made sure solenoids and wiring are placed right. What did I mess up? Not enough fluid, TC?.. I should add that reverse was basically nonexistent before.
