ODB II error code need help! : P1762 Overdrive Band Failed Off

[quasarsky]

i went to mr. transmission, he tried to rip me off i think any ideas on what he said?

well i went to the shop. the guy said that it was something wrong in the transmission and that he would have to drop it, and the transfer case. he said the noise was coming from the transfer case., and that my car wasn't going into 4th gear all the time (at 35 mph)

now, he also said my light i had on at autozone, the code they gave me, was the code for a solenoid.

now, he also said my 4th gear wasn't going into gear all the time. now couple that with me not hearing the noise when i slow down all the time, plus the code is for the solenoid, plus i'm not going into 4th gear all the time... this sounds like it could be a solenoid problem right? are solenoids expensive to replace? the noise sounds like an electric motor, NOT gears grinding. and if this was gears my transmission would have given out a long time ago. this noise i've been hearing erratically has occured for the past 3 months. i've driven it about 7000 miles in that time. i highly doubt my transmission would have lasted that long if something was mechanically broken inside it. any ideas?

the fact he didn't want to scan it with the code machine, he just said 'its something in the transmission, it needs to be dropped with the transfer case, i think thats just bogus. is there any tests that can be done to the transmission besides dropping it? valve pressure tests? testing the solenoids? testing the torque converter? how much for those tests, if they are possible without removing the transmisson? please someone!






My check engine light has been going on and off the past 2 weeks. The overdrive light does not come on unless I push the button though. I just got this code from going to autozone, P0 1762, a google search turns up "Overdrive Band Failed Off"

Anyone know how serious this problem is? How much it will cost to fix? I read one person had a

this thread too appears to be helpful.

No 2nd Gear
No 3rd Gear
No Engine Braking In Manual 1st.
Out of specification pressures controlled by the transmission main control valve body separator plate may be the cause.

I'm thinking the one in bold may be my problem, or a bad solenoid. The transmission still shifts fine. However the past week having cruise control set to 60 mph the rpm's were bouncing from 2 to 2 1/2, on a flat road. The car drove fine yesterday. Could this be related to code? On second thought my right tired was flat, so maybe the increased rpm's were related to the tire slipping because it was partially flat. Also my car has been making a strange noise the past few months as I wrote in another thread. One mechanic said it could be the transfer case clutch solenoid sticking some making the noise, the noise is like an eletric motor whirring. Perhaps its the transmission pump I'm hearing? Cause I have a blown gasket in the transmission?

"Check engine on, is this a switch/solenoid problem or is a band adjustment truely needed?"

except my check engine light is going on and off.

I'd do what you are thinking, namely rebuild the VB and upgrade it. WILL that solve the problem for SURE? Maybe notm but has a good chance and will be a worthwhile thing to do in any event. While the pan is off look for pieces of the OD band anchor - just in case it is broken.

 

[BrooklynBay]

You could tell if the band is broken without dropping the pan by adjusting the stud outside of the case. If it just continues to tighten, then it is broken. It should stop by a certain point.

Also sounds like your transfer case is beginning to fail. All four tires must remain close in diameter or TC failure is accelerated. If you end up needing one I can meet you somewhere in Virginia with one.

well as for me, I would rather drop a pan and change some fluid and a filter than adjust a band on an installed tranny... but that's me.

i tried putting the car in reverse at mcdonalds beause i was too far away from the window, and it made a horrible noise when i tried, so i had to put it back in drive. when i got home i put it in park. i tried reverse, drive, park, and didnt' hear the noise. but it did make a slight noise like i could hear it go into reverse. i know the bar that shifts the transmission that goes into the side of it probably needs to be replaced soon (trans. shop told me thats where my lil leak of fluid was coming from) but i doubt thats causing the noise. i always check the fluid and its fine. could it be something else?

 

[Glacier991]

It is always difficult to seperate trans noises from TC noises. The fact youare throwing a tranny code strongly suggests it MIGHT be a tranny issue. Your noises are not good. I think this one MAY be a rebuild issue. That is not a definitive answer, just a gut guess... coming from the guy who thinks WAY too many trannies get rebuilt unnecessarily.

Do you have any engine braking? I'm thinking that the rear one way sprag might have stripped. That rear section is a high wear area. You could have a stripped band(s), or broken bands. Drop the pan, and see if you find any metal parts in there.

what is enging braking?

tonight at mcdonalds i stopped too far ahead of the window. so i put it in reverse and i hear a horrible high pitched noise. its backing up but i hate the noise so i just keep it in drive. i drive home, and try it in reverse, forward, park, etc and dont' hear the noise. i have no idea . putting it in reverse at home i could hear it going into reverse, but it wasn't that loud.

Does the engine feel like it is running on without a positive engagement, and no change in RPMs?

? well for awhile when i go about 60 mph the rpms were spiking from 2 to 2 1/2 and back to 2 then back up to 2 1/2 rpms. i don't know why. but the rpm's would drop back to below 2 and settle right on 2, when going about 65 mph. i don't know what that was.

is this what u mean by running on without a positive engagement?

 

[BrooklynBay]

That sounds more like the TCC solenoid engaging, and disengaging. I was asking if your RPMs run on, and feel like there is slippage even though there is still some positive engagement. Do you have a large RPM swing with a slipping feeling, then a little grab just enough to keep you going?

[Glacier991]

Yes there are tests that can be done. You can test the solenoids without opening anything up by using the FORD transmission tester (most FORD dealerships have one gathering dust somewhere). That same tester can shift the transmission without using the computer. You can also do a pressure test on the transmission. And of course you can pull codes.

 

[BrooklynBay]

There are all kinds of transmission testing tools, like a 0-300 psi pressure gauge, Rotunda solenoid tester, OBD-II scanner, air test plate for a valve body, etc. I they are experienced in diagnosis, they wouldn't need to use every tool they have just to see why it is throwing a code. There are some tough things to diagnose from time to time, but if they remove the pan, test the solenoids, wiring harness, and look for broken parts, they would most likely find the problems that are involved.

Ok, guys. I too have this tranny code. P1762 Overdrive Band Failed Off. Everything works great except the Overdrive. Trannys make me nervous as I've never really worked on them before, but I'm always up for a new challenge. So, what was the finaly solution for your Issue? And would you recommend an inexperienced tranny guy try it?

well there's a few things i think it might be, its just finding a tranny shop that will do the cheaper tests (alot cheaper than dropping it). seems like all they care about is $$$$. :fire:

its probably just adjusting the overdrive band (can be done without dropping) the epc solenoid needs replacing, or the servo pistons need to be replaced. i really doubt its anything else. but who knows. its fine for now, the code hasn't come back on but i haven't gone above 45 mph either

 

[Fish-Aholic]

yeah, well I got an incredible deal on this explorer, only $1500. But since this is causing the check engine light to be on, it is failing the Virginia Emmissions inspection that I am required to pass so I have to cure the problem one way or another. I am going to take my laptop over to my parent's house (they have a garage I don't) today and start exploring. Hopefully the band is not broken and I can just adjust it and be fine.....

heh i looked there . closest one is about an hour, hour and a half away. . still gotta save up the money first for the tests
