Getting Side Ways. Do you intend to ruin that solenoid? Hi Gab, I'm sorry to say this but I think you maybe mixing your solenoids up, unless I'm mistaken. From my understanding the S5 variable pressure solenoid VPS can indeed be damaged by a continuous DC supply, due to the coil resistance being low from memory around 5 ohms. The S5 is intended to be supplied via a Pulse Width Modulated PWM supply and it is the variance of this supply duty cycle that is used to regulated the hydraulic line pressure within the gearbox and thereby vary the line pressure during shifts etc.
The solenoid in question is not the VPS but rather one of the shift solenoids S1. As you'll note the resistance of this is far higher than the VPS 23 to 45 ohms. Assuming a supply voltage of 12V and a coil resitance on the bottom end of specification 23ohms , and ohms law results in a coil power of 6. As you'll note this power level is very low and the actual solenoid is lower than this 5. Unfortunately I can't find any datasheets on these solenoids however for comparison I've attached a Bosch Rexroth datasheet of a slightly higher power solenoid for comparison DC supply voltage, current and power One observation I did make during testing is that if the solenoid was indeed operational then when I initially applied power I used my laboratory power supply not a starter battery then I would of expected to feel an almightly joult as the armature moved followed by the buring out of the coil.
I felt no joult. Also the coil resistance and associated current has remained constant the coil neither short circuited or open circuited. What are your thoughts? Ahh yes, pottentially I am mistaken, I didnt know that much detail about it.
But when I worked in an automatic transmission place we were told not to put 12V to any automatic transmission solenoid in any car, as often they are supplied with 5V or similar from the TCM. I was of the understanding that it would damage it. Is the pump working properley and do you have a clean filter? Are you running the correct type 95LE fluid? As to vehicle, a stock series 1 AU Falcon wagon so nothing exciting I'm afraid.
Unless a gas conversion lights someones fire! Best regards, Arfur. Also I've worked out simple method to repair sticky solenoids, simple as: Basically shake the solenoid if the plunger is loose you can hear it rattle, if no rattle its stuck 1. Testing: it appears the solenoids dont have a return spring inside, must use the pressure of the oil.

I have not once got the wrong part I ordered or had a delay from a "backorder" they are extremely good at packaging for delivery and shipping time. Cleared code and now getting p again and transmission is in limp mode. Thanks for any help you can give me. My Prado TX is behaving some how not namal when I engaged drive it forces the gear and produce sounds, what would be the problem?
Chevrole malibu v6 LTZ shift sol valve 1 ctrl.. I make computer check on my car and I get this massage.. I visit the dealership and I asked about the solonid valve but they don't know what I mean and what is that exactly I have Mercedes c cdi 2. Hello, I have a Toyota prado that the automatic transmission is giving me a rough shift just from 2nd to 3rd when I drive slowly.
When at high rev it changes smooth. Problem started after I did a fluid and filter change in the tranny. The guys had forgot to tighten the refill plug and I lost oil and car could not go in gear. They repaired whatever was the issue to stop it from going into gear and ensure correct oil level is in tranny, however this problem cannot be identified.
Do you have any clue what could be the issue as no errors when scanned. International truck i pro sleeper is failing to engage gears and is stuck in a gear. Hi, I have a Honda Crv 1st gen. Code is P shift solenoid valve B failure. As per stated above, is this an electrical problem or the solenoid failed? Thanks for your comments.
I have Acura cl 3L 6 culture. I'm having a hard time finding out what is wrong with my yukon denali 05 transmission I have changed both shift solenoids and filter with new fluid but still no 1st and 4th gear. I have a Re5r05a that doesn't want to go in reverse for quite a while. I took it to a transmission shop and they said there was nothing electrical wrong.
I changed the screen and fluid before I took it to them. They said I need a new transmission. Would a faulty solenoid cause this issue? Your help is greatly appreciated Regards David. Hi, I've bought a ford explorer with k miles on it.
The transmission doesn't shift the gears only one forward gear and the reverse is working. If I put it in reverse the car shakes for a second. And last: if I put the car in "drive" and put my foot off the break - pedal and don't push the gas pedal it will almost not move forward. So my guess is that the shift is worn down but ok?
And that the major problems are coming from a broken shift solenoid or a bad wire? Any help would be appreciated. Yes the easiest way to figure this out is to read the trouble codes and see if there is a problem with a shift solenoid.
Check the condition of the transmission fluid also and replace if it's very dirty. However the easiest and cheapest way is to read the trouble code memory first. I have a Buick lacrosse cxl I need to replace a transmission shift solenoid 5 but how to know what's it's the numnber 5 solenoid..
You do either need a wiring diagram for that specific model from the transmission control unit to the shift solenoids, or unplugging one solenoid at a time and check which trouble code you are getting, with this method you can recognize it easily! Have a 04 Corolla the transmission stopped shifting and the codes that came up were P — Torque Converter Clutch Circuit Performance or Stuck Off and I think is was p shift solenoid I know it was a shift solenoid code not sure if it was p or p I would start with a transmission fluid replacement.
Heard of corollas before with the P code which got fixed by a fluid replacement! Drove it home had some transmission hard shifts later that night and the next day the car would not go into gear. Had it towed to a mechanic who called and said the transmission would need to be replaced and that their code reader said there was an internal transmission failure and that is what caused the other codes to show up.
How true is this statement? Also before sending it to the mechanic shop i drained and replaced the transmission fluid. It was more dirty than expected for just draining it less than a year ago but still pink, not burnt and no metal shavings noticed. In this situation I would ask a special transmission workshop if you know any. Before replacing the transmission you have to measure the wirings and checking inside the transmission control unit for any transmission fluid inside it.
It sounds strange, but sometimes it will push oil through the harness into the transmission control unit. However, they should measure the shift solenoid and the transmission fluid temp sensor from the transmission control unit before any replacement in my opinion. I have a 04 Bonneville with 4. It shifts fine when cold but when warms up it can shift erratic from even then sometimes it shifts fine.
The car has 65k on it now. I did change the fluid and filters in it 1k ago. I bought it with 62k. Any info or ideas would b greatly appreciated.
My lock up Solenoid seems to get busted or dead very oftenly on the shift Solenoid lock up type only when replacing the old busted one and after four days it again got busted or malfunction again. Could it be a electrical short circuit on the plug in the solenoid which is connected with three solenoids in series on my AF Transmission on my Toyota Prado Tx, KZJ95 model. Please do let me know the reasons quickly! You'll need to take certain precautions before removing the transmission oil pan.
TIP 2: Before removing the transmission pan to test the shift solenoids , let the engine cool down completely. Transmission fluid gets hot and remains hot long after the vehicle has been turned off. Be careful, take all necessary safety precautions. Think safety all of the time. So if your transmission is slipping, replacing the shift solenoids, even if they're fried will not solve the slipping issue.
