- In this video, i had a Dodge Dakota come in with input speed sensor codes, after changing the input speed sensor the problem remained, so i had to graph the signal to see if i was dealing with a wiring issue or PCM. Thanks for watching.
Hard to find honest mechanics like this
These are my favorite videos, showing the diagnostic process. It's where I struggle the most. Thanks for filming this one!
Thanks for watching
Great! Right to the point! Good way of putting things so logically, to verify function or failure of each section.
Thanks Cuba, always nice to hear from you.
Love the diagnostic video, a change from the teardown video. Both types of videos are always very informative.
Thanks for watching
I’m serious idk where you’re located but you seem much more knowledgeable than anyone in my area
Im in New York on Long Island
Nice diagnosis. Thanks!
Thanks for watching
Another great job!!!!!!!!!
Thanks Joe
Good morning,
I left my Koleos 1 2.0 dci automatic gearbox this week at the garage to change the crankshaft seal on the flywheel side.
I picked up my car today, I did 50km on the highway without any problem, it went through all the gears and was flexible, and when I arrived in town, my box started to have trouble shifting into first gear, then at one point it got stuck in 3rd gear. When I switched to manual, it remained in D. Finally, a message "regulator to check" appears.
By restarting the car, it's ok for a few minutes then it starts again.
I went back to the garage, we did a diagnosis and when we accelerate, the turbine speed is at 0 when we accelerate, and this blocks the gear change, we have to restart the car.
Here are the diagnostic errors:
- P01717: turbine speed sensor circuit (active)
- P1525: consistency of multiplexed information for cruise control, the information is not compliant (active)
- P074491: torque converter clutch ev function, converter lockout control (memory).
Do you know where this could come from please?
I never heard of this car, do you know what transmission you have
@@GaryFerraro Good morning, This is the Renault Koleos 1, year 2015 with 155,000 km. It has an automatic gearbox, and this car has many common parts with the Nissan Xtrail and Nissan Qashqai (Aj0 gearbox from Jatco, with torque converter)
@@billal93800 ok, We don't have these cars here either but i have a chart that will show, let me see what trans is in those cars
@@billal93800 I think you may have a CVT Transmission in that car
@@GaryFerraro I have a torque converter transmission. When I plugged in the clip, sometimes the turbine speed is 0rpm while driving, sometimes it's normal. Is it a speed sensor problem?
Very good video, thank you
Just stumbled across this video I was wondering if you had an idea about mine. I just rebuilt the engine and it doesn’t go past 3000 rpm when I drive and doesn’t go passed 60 what do you think I should check first?
Saludos amigo Gary.
Thank you my friend
hello. Could you please explain how we get turbine reading with the vehicle in Park? I read somewhere that the input shaft is connected to the clutch. (inside of the transmission). I would think it would read when the vehicle is in gear.
The input shaft is turning because nothing is applied in park and neutral. When you put the car in drive with your foot on the brake the reading will go to zero because the drum stopped turning because the clutch is applied, as you start driving and the drum starts turning the reading will come back
@@GaryFerraro thank you so much!
@@bbmd2200 sure, no problem
bro i got the same code on my g37 2010 journey 3.7L i have no idea how to fix this bro can you please help me out
Gary, I have a 2007 GMC Sierra 1500 4x4. I replaced the speed sensor on the transfer case. I was getting that code along with hard shifts. Trans is rebuilt with 38k miles on it. I haven't driven it for more than 5 miles after seeing this code. Do you think it's the ground issue? Also sensor was in the transfer case. Did I change out the right sensor? Or am I supposed to fix the ground only, the one in my transmission? Where would it be located at if I did the ground wire fix?
The sensor is located inside the transmission, not on the transfercase
Is this a 2 wire connection?
I can tell you know exactly what you’re doing can I just have my car towed to you to be repaired?
2010 Cobalt, I notice my ISS value is not present often on a cold start. Is this normal? I have to rev the engine high to read and if I put the car in gear the value goes to 0 (normal) but when back in park will not reappear. If I drive the car and the value suddenly appears it locks up the PC duty cycle value and transmission shifts hard based on value it froze at. If sufficiently warmed up I can reset ignition and value appears OK after start and car drives well. Usually drives OK for the remaining part of the day even hours later. Any idea?
That should be 4T45E trans, you should get a reading in park, ISS is probably no good, there is also probably a code present
@@GaryFerraro Yes 4T45E. So right from cold, I should see an ISS reading right after start? Have you or anyone confirmed this? It's crazy after the transmission or transmission has "warmed" slightly it works perfectly after a reset.
Louis Baiani The input speed sensor is probably no good. I've seen this before with this trans
@@GaryFerraro as you know I ended up changing the speed sensor and got a surprise while testing the harness from outside the tranny after it was put back together. The code was being tripped and in no way I could shake the behavior as before when warmed up. I found one leg was shorted so what I did is cut the wiring from the sensor and placed an audio isolation transformer in between. That was two months ago, never shifted better and no code!
hi Gary! my car has a ECM, TCM and a BCM. which one is my computer that I need to replace?
What kind of car do you have and what code?
So your saying add a ground ? I’m confused I got code po717 and only hard shift from 1-2 and that’s my only code so should I change the input speed sensor or ?!? I just rebuilt the transmission and I have no will to tear it down again !
You do not add a ground, you have to cut the wire because the TCM grounds the sensor, so if the TCM is no good, you cut the wire 3-4 inches away from TCM, tape the 3-4 inches out of the way and ground the other side
@@GaryFerraro so if I cut the 3-4 inches from tcm will it fix my po717 ( mine saids turbine no signal ) if I ground it after the cut will it fix that issue ? Cuase I already replaced the speed sensor. It’s a 2009 Silverado 4l60e btw
@@Carlos-ve1je Speed sensor is internal, you had the trans out? Grounding the wire may or may not fix it
@@GaryFerraro for my model I have a speed sensor on the outside of my transmission on the shaft so I changed it but code was still their the internal one I have is the turbine sensor and it saids that I have no signal with the turbine I was asking if by cutting it and grounding it will it fix it if so I’ll do it next day 2marrow morning
@@Carlos-ve1je what is the year,make, model and engine size of your car?
very big thanks gary for all your videos
i am strugling with toyota u250e that keeps burning the overdrive clutch do you know what causing that is there a problem with the valve body
when you say the overdrive clutch, is it the clutch in the drum right behind the rear cover?
Gary Ferraro yes the clutches that applied in 3.4.5
valve bodies do have issues, with stuck valves, a big problem with these transmissions are the solenoids, i always change the SL1, SL2 SL3 and the SLT (pressure control) solenoids, if these are mechanically bad, they drag the clutch and burn it out, you should also reset shift adapts
Gary Ferraro gary when i opended the trans from the back cover i found the top sealing ring inside the drum where the back cover sleve goes the back cover sleve where the top sealing ring was worn out
The ring itself or the ring land?
Hello, Sir. I am dealing with a p1715 on a 2004 nissan murano I/P PULLY SPD. I see that the I?P PULLY pid is 38 mph with key on and idling. I believe it is supposed to be close to the tach. Should I replace the input steed sensor after confirming wiring integrity?
Carlos It reads MPH or is the reading RPM?
@@GaryFerraro I think it's rpm because when driven, it was almost equal to engine speed. The MPH I saw was pids from vehicle speed sensors. One was 0 mph with the truck idling and the other 18mph. i expected both to be MPH since the truck wasn't driven.
@@perez7667 Is the speedometer on the dash reading with the car not moving?
@@GaryFerraro The speedometer reads 0 mph, but I saw 2 vehicle speed sensors data. One reads 0 mph and the other a low number. Both of them change as I drive,
@@perez7667 ok so while driving one reads zero and one works? which one reads zero and how fast does the code return once cleared
Excellent video I help me have cruze automatico 2011, 6t45-40 cod P0717 input speed sensor low circuit, what's the problem please. Greetings from tulua Colombia
ovidio libreros do you have access to a scan tool to see if your getting a reading on a scan tool
ovidio libreros Greetings from New York
Will this be same diagnostic for 06 nissan pathfinder? I got a p0717 too. Im thinking about replacing tcm but i just want to be sure
With that code, the Tcm/ valvebody probably is the problem. Look at the fluid make sure no water is in the trans, the radiators like to go bad, if that is the case, the trans should be rebuilt
@@GaryFerraro my fluid still red plus i recently make a radiator swap for a all aluminum cfs one because i was aware of that coolant problem. If i replace the tcm should i still put new fluid on?
@@leod7058 If clean you should be ok, If you get one from the dealer, it will have to be programmed, can't really go good used on these
@@GaryFerraro so a fully refurbished wont be good?
@@leod7058 did you ever replace your TCM valve body? Did it fix the P0717 code?
