Default Re: O/D Off Light Flash

Hey everyone, my first post here.

2002 Ranger XLT SOHC 4.0l 4x4 Off Road pkg. 115xxx miles. purchased at 60xxx miles, 6th owner, carfax showed transmission service at ~50xxx miles. I do have a bit larger tires on the truck too, 265/70/R16.

A few days ago while searching for a new house in Portland Ore. I was traveling through residential neighborhoods, stop & go, 25mph max at any given time.

After about 20 minutes of driving I noticed the trans slipping from 1st to 2nd gear, almost like it was searching for 2nd and having a hard time finding it. O/D off light began flashing so I pulled over, immediately shutting it off and opening the hood. I looked in the engine bay for electrical fires, and under the vehicle for leaks, none. I started it back up and checked the fluid level, which seemed a bit high but still clear/pink, and smelled fine.

I had noticed a few days earlier a problem on my way to school, only when the engine was cold, ~ 45*F that there was an apparent slip happening. After a mile or two the trans shifted fine, which was really the next time I had to shift from 1st to 2nd. When it would happen though I would have to take my foot off the gas and let it spool down to grab that gear.

Also, I notice the truck idling low and hesitating when reversing out of my driveway in the morning, also only when the engine is cold.

Now, I know that I should have been more diligent the first time I felt it slip, but I wasn't. So here we are.

I have Oregon Transmission Center coming with a flatbed in the morning to tow away my truck, mainly because they offer free diagnostic & inspection. I'm happy to pay towing fees instead. They do have upfront pricing on full rebuilds too, $1995 with 3 year 36,000 mile warranty...

I'm going to start a new thread specifically about this too.

Make sure you let us know what the outcome was, and a final cost as well.

I decided instead of return the call from the transmission shop that I would just pay them a visit. Surprise!
As stated before the truck was picked up by their tow truck, I had never met them or seen their shop so I thought it was a good idea.

I met with their lead technician, they showed me around the shop, let me get a look at my truck and the transmission, showed me different transmissions in full rebuild stages, etc. etc.

At this stage they are "inspecting" the solenoids, bands, servos, whatever they can without pulling the trans out of the truck.

I should get a call again on Monday with the status. I'm confident at this point that I found a honest shop based on the conversation with the lead tech. Just waiting on the outcome...

Yikes! 2001 Ranger V6 auto 3.0L error code P0773 - incorrect 3rd gear ratio...

$1800 estimate, actual rebuild estimate after transmission opened - ugh, tough time of year for $$$

Had started a new thread the other day with a similar issue & just seen this. Was riding around town & got on the interstate heading home & notice the o/d off light flashing. Wasn't far from home & it wasn't really doing anything so I continued on. Got on the off ramp, came to a stop at the light, when I took off it hard shifted through the first 2 gears. I got home & shut it off. When I started it up & took off it was fine. I think I will start with a fluid & filter change as its been a pretty good while since its been changed. Btw the fluid level was fine.

Typically, a P0733 code (you had a number off) means that the slip ratio between the toque converter and the actual gear ratio is off due to some kind of hydraulic or mechanical failure. If the trans shop found any kind of particles in the filter, than a trans tear down is warranted because they need to find out where the particles came from. Your estimate is typical of what trans shops charge because nobody else will work on transmissions, and they know this. The parts are cheap, it's the labor that makes it expensive.

Best of luck on the replacement, and should things still not be right after they rebuild it, take it back and demand either a refund or for them to make it right until the problem is fully fixed.

Definitely at least try the fluid/filter change, but make sure you take it to the Transmission shop so they can at least read and clear the code if they do that for free. When you get the code, bring it back here and post it up! Good luck!

Got the Ranger back from the shop (national brand of transmission repair), and the problem was a busted gasket inside that was allowing fluid to escape into another channel. The guys were cool enough to let me have a look and the burst area was between the two inner hydraulic valves that looked like a black membrane material.

100's of parts on the workbench confirmed this was wayyyy beyond my weekend wrenching skills.

Final bill was $2100, mostly labor, new bands, new valves, new credit card balance, but should last another 150k miles, and that is better than a new truck payment.

Not sure what caused the internal gasket to burst, but I distinctly remember passing a car and the engine RPMs revved up like the clutch was engaged...I pulled foot off pedal, waited for the re-engage, and went on about my business. Within a few days, flashing O/D began.

Hard to tell if anything's busted just from that. I mean, if the tranny overheated that's never good. How big of a trailer were you pulling? I mean, you put a lot of strain on it, and a bigger tranny cooler may fix the problem of overheating but if what you have standard isn't cutting it then your transmission probably isn't meant to tow under those conditions. I would drive without a trailer, if your transmission still works you might not have done too much damage. Still no O/D though? Also, when you said a light is flashing which light are you talking about, the O/D or the Check Engine? I think you should be ok, just be careful what you tow.

I have a 2002 Ranger, 4.0L, 4x4. I have the same issue and the blinking O/D light does go away if I shut off the truck and start it back up. Is it possible to diagnose the "valve body & gasket" issue by visual inspection?

Also, where is the speed sensor located? Does anyone have pictures of where the speed sensor is and the replacement procedure?

Thanks

The gasket in question usually "blows out" between the EPC solenoid and one of the shift solenoids....it is noticable if you know what your looking for.....there is an updated seperator plate with a bonded gasket on it to help prevent this from happening again

Pull your transmission pan down, drain all the fluid, and then remove the transmission filter. Cut the plastic lid off of the filter, and then pull out the fibrous filter element. Open it up, and you may find pieces of blown gasket inside. However, just because you don't see any pieces of gasket doesn't mean the gasket didn't blow. You could have a piece of the gasket stuck anywhere fluid passes through the transmission or transmission cooler.

Best thing to do is to have the codes read, it will at least tell you where the problem area is.

spent $2800 bucks 3 yrs ago to get my trans rebuilt... trans never was fixed 100% right. 2 months after the work was "done", I would put it in gear and nothing would happen for several minutes, usually on rainy or damp days.. I just learned to live with it...

now My trans is shifting hard and this light is flashing...

I'm hoping its a low cost fix... going to the dealer next week to have it checked out. their charging $210 just to test it. testing takes 2 days.

I had a 2000 and at 69k I played this game. Took it to 3 places. Including the dealer cost me 150$ and they couldn't give me a print out. Codes this and that running too hot, you name it it was the problem. They all said NEEDS TO BE REBUILT.. to the tune of $3000. well to make this short I fixed it myself spent a few hundred bucks and that included buying tools to do it. it was 14$ worth of blown valve body gaskets, a filter and a fluid change. All can say is good luck.

thanks for the info. mine was rebuilt at 86,600 miles or so... so the fun continues...

my truck is 11 yrs old, had 10,000 miles when I bought it used... has 111,200 now... other than the transmission, I've had good luck with the truck... only other expensive thing I've done is brake jobs...

oh, I do have an antifreeze leak that is small, but it's coming from around or behind the timing cover... dealer wanted 900 bucks to fix it. so needless to say it's still leaking... 900 bucks can buy lots of coolant. lol
