ADPTraining: We developed 2 items for transmission diagnostics:
Lexii Anderson: I have a 01 impala my car is stuck in high gear.. It want pull off in drive
I have to put in gear 1 to make it drive and switch my gears from 123 D
what does this means. I have change the stranier of the tranmission and
chek the wires what else can be the problem please help
Bill Reid: I have a 2002 grand prix and it shakes a little getting up to speed, when
I get up to speed it doesent want to shift into overdrive for about 10
miles then it shifts. code p1811 came up what could the problem be ? PCS ?
Marco Lara: i have an oldsmobile silhouette 2000 and i need some help on replacing the
transmisson pressure control solenoid.
paryabaker: I have 2003 buick regal that will not shift to overdrive. Sometimes 1st
gear slip and cause the car to jerk forward when it suddenly engage. There
are times that it take times to shift from 1st to second or second to 3rd.
Change fluid at 100, miles. what are the possible cause?
jertkonik: my 2002 mazda protege5 has a flashing OD light and a code for Solenoid A
Pressure Control Failure. Car is running fine, some lag in shifting around
40mph, but nothing I'd complain about. Fluid is red. Shop wants to
replace 3 solenoids, which I can't afford right away. Will I be damaging
the car if I keep driving it?
matt baker: i have a 92 dodge dakota 4x4 with a 318 driving the other day stoped and
went to go and it was like it wasnt in gear shut it off for a while started
up and only drives for short distances now and does it all over again and
ideas? i have been told many different things just trying to get some more
elohim899: When I turn my car (2002 honda civic) on, I will put in it drive and it
will only move 50 yards or so. What could this be do you know? I had a
mechanic look at the car, but he did a poor job, only checking to see if
the car would turn on and he said it was the transmission and wants to take
the transmission out. Other friends of mine have suggested that it is an
item called solenoid as seen in this video, while others have suggest other
things. Once again, can any one help me and give me suggestions, what could
Alex Rivera: need help with a 97 4x4 1.6L tracker it will shift up and down but it wont
get the 3rd shift its a 3 spd transmission. i obd it and it comes out
p0744, at 40mph it at 3,000 rpm. think might be the tcc not locking up or
it needs to get 3rd and then lock up???? thanks for the help
Ihab EL.Zareif: dear i have Chevrolet epica 2007 giving this codes p0762 p0733 p0732 p0717
p0700 p0606 and my transmission not shifting to reverse ? any suggestion
Luis Rivera: I have a 1999 Chevy Malibu , When i swift from Park to Drive or Reverse It
shifts hard and feels really bad . Could this be the problem?
Ilian Nachev: I have to hit the gas, in order to keep it from shutting down. So far it
has shut off twice since I had the music loud and didn't hear the engine.
When this happens, I could hear a whining noise coming from under the hood
as if something there is struggling. If I don't hit the gas at that moment,
the car feels as if I am applying the brakes or something is stopping it.
Furthermore, the car would surge ocasionally when accelerating from a slow
roll between 2-3K RPM. Slow leak is observed again.
ADPTraining: I need to know which code was it exactly. There are a few codes for the
PCS. Yes, you can replace the PCS. It is a solenoid and shops don't just
replace it because if something else on the trans goes a few months after,
they don't want to get blamed. Some dis assembly will be required on your
part. Post back with more...Mandy...
verally1: One thing I also noticed is the overdrive light blinks 16 times every
single time I start the truck. Then it does shift into overdrive, but it
never let's me turn off overdrive if I wanted to. I could before the
elder ls: Thank you for uploading your video..."GREAT JOB"!!!
Ben Madrid: 2001 Aztek 3.4L V6, from the scanner: DTC 0/2 P1810 01/02 P1810 P 02/02 any
help is greatly appreciated thank you!!!
ADPTraining: @ADPTraining CONTINUED: Second, if tranny shifts fine and smooth it is
surely an electronic fault. If tranny is not shifting properly and ISS OSS
checks out fine, then you have a mechanical issue. Post more with further
details so that we can uncover the issue. Good luck.
Michael Pusztay: My Impala has got 270,000 on it, and I tried looking the history up to see
if my trans was ever replaced or rebuilt, so its probably the original
trans. Im currently fixing the intake manifold gasket on this car, and in 2
months Im getting the trans rebuilt, So wish me luck Im trying to get this
car to last another 2 years til college is done. Its got so many new parts
on it that its worth getting the trans built. Thank you for all your help.
ADPTraining: If a shift into any gear other than reverse and forward engagements takes
longer than 0.65 seconds to complete, code P1811 will set. The ECM will
then command maximum line pressure inside of the transmission, resulting in
harsh shifting. ECM will also command the check engine light light to be
illuminated when P1811 is set. Basically, the PCM is sensing a slip, and is
increasing line pressure to maximum in order to prevent the transmission
from hurting itself further. CONTINUED 1:
TheStealthyIReact: i have a 2002 grand prix gt and it shakes when i accelerate, but once i put
it on cruze or let off the gas the car rides smooth. help?:p
SebtorDude: Very helpful video! I got a "Pressure Control Solenoid Malfunction" reading
from my Ford Mustang GT's 5R55S Automatic Transmission. Is this necessarily
a broken PCS or can this be caused by low transmission fluid or a clogged
transmission oil filter?
ADPTraining: I hope you used the correct gear oil for Honda CVTs. Well start by scanning
the transmission or engine for codes. Otherwise I have nothing to go by.
MusiikN0w: I have a 1998 dodge ram 5.9L v8. and it shifts a little late, and
downshifts hard in 4th gear, shakes the truck a little bit, and a few times
i got a code for " too much pressure in transmission" or something like
that.. i forgot what the code number was.. can you help me please??
ADPTraining: I agree, modern consumers should get educated and learn as much about the
system as possible. Yes, often times a $100 part is all you need. But,
there are good repair shops out there. It is also a risky situation. If you
do replace the PCS and the transmission goes a few months later, the shop
gets blamed. Any court of law will fault the repair shop first, regardless
of what they did. Education and knowledge are the consumer's best
choice...Thanks for posting...
ADPTraining: You need the manual for component location or any other software. Otherwise
pay a one time fee at Alldata for your specific car only, which is cheap
and full of information.
ADPTraining: @SunsetNap YES it can. The NSF tell the TCM which gear it should be on.
There's a varying voltage that goes to the TCM (Trans Computer). It's not a
simple on and off switch indicating Neutral and Park. On most systems the
TCM then broadcasts the gear position via the vehicle network for the dash
to show the shifter position.
ADPTraining: That's impossible for me to know. What I don't get is that it seems you're
dealing directly with a Honda dealership, why can't they fix it? With the
factory scanner you can do and command all sorts of scenarios with your
Honda and quickly see the problem. I'm a bit perplexed.
ADPTraining: Yes, but in my opinion it makes things a lot simpler...
Tynan Mangion: Fantastic insight into my problem. Thanks
ADPTraining: Yes, most YM 2000 and up are dealer tool dependent. Having said that, lots
of Aftermarket scanners also have this capability now. By the way,
resurfacing a trans valve body isn't easy. Most shops just replace the
whole thing with a new one at a higher cost to you of course. If warped
you'll need to resurface the valve body on a milling machine or the old
fashioned way, use a 2'X4' mirror and glue sandpaper to it then run the VB
to resurface. Old trick I learned a while back. Good luck.
ADPTraining: OK, the fact that the voltage starts at 3 and drops to 1 says that as the
PCS gets hotter, resistance drops, hence 1 volts seen at the end. One volt
is kind of high, meaning that there's excessive resistance at the PCS
windings. Having said that, compare by measuring resistance, with solenoid
hot. These units normally carry very low resistance. Or almost like a
straight through wire. Your PCS doesn't seem shorted, which is more common.
ADPTraining: If stuck in 2nd gear, then it's limp-in mode. TCM saw a discrepancy issue
and set LIM. Erase codes and reset adaptive memory. Let me know if that
ICotFire89: ADPTraining, I have a 1999 VW Passat that is reading the code P1818. Does
this automatically mean that the PCS needs replaced or could their be
another problem? Is car okay to drive with this problem or will it
inevitably cause other problems?
benmixmaster: Want more. I say find the maker and seek what more there might be
available, Dont hesitate if you want to learn automotive electronics,
Diagnostics This Many Conception has much to offer . Start by looking at
this site. I seen much of what I needed for many years, But didn't know
about it's availabiity. Dont forget american made from what I understand,
Dont missout on what you need and your american country needs.
Jesse Wilson: i have a followup question about my 05 town & country that was posted one
week ago, the trouble codes were p 1776 and p 070 transmission wont change
gears when it gets hot. your response was that the valve body was warping
and the linear valve was sticking, an easy fix to repair, i am being told
that replacing the transmission control module requires the Chrys
dealership to reset the cars computer to the new module if not done the
same issues will continue, is this true or false, please. help..
ADPTraining: You seem to be stuck in limp-in mode, which is normally 2nd gear. Scan and
post back with the related DTCs or codes. Thanks...
sonnyray60: I have a 1995 chevy cuburban with a 4L60 E transmission never had any
problems at all now it wont go in any gear but first will not
upshift.....please help we have tried evreything
ADPTraining: Thank you for watching. We also have a new series on how to make your own
diagnostic equipment. Click ADPTraining and go to the playlist that we've
set up there... Thanks again.
verally1: My nissan frontier was damaged due to the radiator failure and cross
contamination. We replaced the radiator, rebuilt the transmission. New
valve body, new clutch kit. It's own external cooler. It runs but, it hard
shifts between 2nd and 3rd. It only shifts like that when you first turn it
on. It might do it once or twice and then it shifts perfectly until you
turn it off and restart it. Then it hard shifts again once or twice and
then it shifts perfectly again.
ADPTraining: Mr. Smith, you can not test 5 Ohms. Forget using a regular multimeter to
check such LOW levels of resistance. There are low resistance testers, but
expensive and not normally used by auto techs. With normal equipment, at
such low resistances, it is not possible to measure it. The readings are
elder ls: Tranny Shops are in business to make money & lots of it. 10/10 they are
going to say u need to REBUILT ur tranny. It's something how I mistaken
came across this information w/ my own vehicle. When trannies are cutting
up & not shifting prop, it's usually that the PCS has gone bad & needs
replacing. Depending on where u get it, that part cost $85 to $190 new
(ebay is a good source), & u can replace it urself. It beats being BEAT out
of $1,200-$1,800 for a rebuild u DON'T NEED!
elder ls: Isn't it something how tranny shops say u need a REBUILD! And, all they do
is let ur car sit around the shop for a week or two, then replace the PCS
(Governor Pressure Sensor Transducer & Solenoid) which doesn't cost them
much to get anyway because they usually have an acct. somewhere but when ur
bill is finalized they charge u a whopping $1,200-$1,800 and then some.
*$85-$190 as compared to $1,200-$1,800...go figure!!! Get ur codes & do ur
research (i.e. youtube). JUST BEWARE PPL!!!
ADPTraining: I've heard of then and spoken to people that use them, but can't comment on
them since I have no experience with BD. They do sound like they know what
they're doing. Having said that, you may be able to accomplish the same
thing by purchasing heavy duty clutches and components and doing the
rebuild yourself, if you're up to it and know what to do. I was rebuilding
my own trans at age 16 without any experience whatsoever and managed to do
it. SO go for it...Thanks for posting.
ADPTraining: No, an Ohm test will not tell you if the part is good. Often times the
shift solenoid fails when hot and it fails due to shorted windings. By and
and large the best way to test a SS is by doing a current rampping test.
This you do using a clamp-on AMP probe and scope.
ADPTraining: Sounds like a linkage issue. Look into the shift lever to transmission
linkage. If trans is defective it won't go int gear no matter what, even if
you push it. Do some visual inspection on the shifter and post back with
blessing makuyana: my honda aria fit cvt gearbox automatic. its not changing gears especially
on high revs. at 120km/hr the reves will be on 6000revs and it doesnt go
down. but on low speed like 80km/hr revs will below 3000rev/min. what could
be the problem. we have changed the gear oil
ADPTraining: @surfmusicjamweedgirl OK, use this rationale: If when dismantling the Trans
oil pan you have access to the PCS, then don't change it (assuming it's
ok). PCS units are the strongest of the all transmission solenoids. They
have to be. But, if getting to it requires major disassembly, then replace
it. 4L80Es are strong units, but you do have almost 300K, so tread
carefully. Good luck...Mandy.
ADPTraining: Depends on the year make and model of your car.
passintyme1: I have a 96 dodge dakota with a 42 re trans.I was having a very rough shift
from first to second and was informed that it might be my shift solenoid so
I changed it and the sensor put it back together but know it wont shift out
of first at all,so I took it apart again to check and make sure my
connection were tight, that i had power and ground to the sensor and
solenoid which I do,buttoned it up and still no upshift,need your expert
advice on this one.
ADPTraining: You can gain a lot of insight on the problem by referring to the OBD-2
code. These are either Circuit-Fault, or Mechanical in nature, also circuit
low or high. Look up the exact definition for the code. Good luck.
