47RE Issues that I've been fighting for over a year now

I have lurked here for awhile, but never gave it a thought to post this issue until stumbling across quite a few posts by tactransman. So hopefully he'll see this, or anyone else that's knowledgeable will see it.

I've been dealing with it for better than a year, posting on another forum. So I'll try to "cliff note" it as best I can.

Prop your feet up and get a tall, cool beverage; it's long-winded..

7/24/12Ok, so I got rid of my 24V with headaches, and apparently picked up a 12V with someone else's headaches.. So, out of the frying pan, into the fire.

I've been working out some kinks on this '97. I test drove it last friday, and from what I recall, it seemed to be fine.. Unless I didn't notice it (my fault for lack of due-diligence.)

At any rate, the issue (for this thread) is the transmission.

Story goes: 2 owners ago, dude bought a Jasper trans, installed it, killed it, warrantied it, killed that one, warrantied it, killed it, then Jasper said "this is your last one."so he pulled the 5spd from this '97, installed the Jasper auto in it, and stuck the 5 speed into the truck that he was using to kill transmissions.

However, he did a piss-poor job, and sold it to last owner, who killed the poorly/improperly incomplete install in short order.So he took it to a diesel trans guy in MD, who rebuilt the Jasper trans using triple disc TC, red clutches, kevlar bands, HD valve body, etc. (parts from HTS Diesel).

Installed a PCM (to replace a non-existant one) and rewired everything, so to speak, or so the story goes.

Fast forward to me.. ( I don't need any "I told you so" type stuff, because I know. Believe me, I know.. One word:

Wife. )

I drove it home last friday, and all seemed well, although I did notice it seemed to rev a little higher to get it moving.. Granted, I'm new to autos, as my '01 was a manual, and the '96 before that, was manual, so I'm somewhat rusty on how they perform/react. Thought maybe the TC had a little higher stall.

Last night, my 7 y.o. daughter wanted to ride around the block in the new dually.. Wish granted. That's when I noticed that something wasn't quite right... No low/1st gear engagement. Neither with shifter in D, or if I manually drop it to L (1), nothing, nada.. it seems to stay in 2nd gear or so..

I will add that if in D, at a stop, let off the brake and the truck starts to creep forward.. give a little throttle and drop it into 2nd, it feels to almost 'drop' a gear, as the forward progress seems to be a more positive engagement, but still no 1st. Driving 30mph, slow prepare for a stop sign, drop lever to 2, it downshifts.. drop to 1 from like 10mph, no gear change/drop occurs.. it stays in 2nd..TC lockup and such works, and with the 4.10s, 60-65mph yeilds about 1900-2000rpm.The Coolant Temp Sensor circuit is fubar somewhere, as is the tach in the I/C. The tach does read through the scan gauge, however, so the Crank Position Sensor seems to be operational.I was told this trans has a 3/36 warranty, but getting that info is proving to be a tad on the tough side..Trans looks fresh, complete with gray paint, Jasper stickers, etc., so it was apparently rebuilt in the Jasper case.Help. I need to troubleshoot this as inexpensively as I can, for obvious reasons.

7/25/12Well, today, on the way home from work it shifted fine and normal. All gears shifted as expected. Weird...on the way home in shifted fine so I do not know what is going on. . I'll see what it does tomorrow, and let you guys know.Well that was short lived. Its doing it again this morning

2 Codes:P1764 (M) Governor Pressure Sensor Volts Too LowThe Governor Pressure Sensor input is below anacceptable voltage level.P1764 (M) Governor Pressure Sensor Volts Too LowVoltage less than .10 volts (4-speed auto. trans. only).P0720 (M) Low Output SPD Sensor RPM,Above 15 MPHThe relationship between the Output Shaft Speed Sensorand vehicle speed is not within acceptable limits.P0720 (M) Low Output Spd Sensor RPM Above 15 mphOutput shaft speed is less than 60 rpm with vehicle speedabove 15 mph (4-speed auto. trans. only).

I'm trying to find a "picture layout" of what is where, on the 47RE. I'm not familiar with this trans, as it's been several years since I've had one.

I do want to check ground and 5V+ reference at the trans solenoid assy. to ensure it's seeing both, as the above codes indicate this could be an issue.

I'm at a total loss as to why it worked fine last friday, then not work Monday, not work Tuesday morning, work fine Tuesday afternoon, and again NOT work this morning..

At lunch, I decided to go drive the truck around the building. Guess what? It shifted fine. This is so weird. Two days in a row, now, where it won't shift correctly the first drive of the day, then will once it's sat for a few hours. It could very-well be a coincidence, but it does seem odd. Monday, when it would throw the two codes, I could clear them and they would come right back. Today, I cleared them, and they did not return. We'll see how it acts when I leave work this evening...It started out this evening doing fine. 1/4 way home, I had to stop at the store.Left truck running. Came out, no first gear. WTF?!?!

George,I checked the plugs, etc. Everything was tight. I found the trans solenoid box, and a couple other 2-wire switches.. one is close to the linkages and solenoid controller on the left side of the trans.. the other is back close to where the trans and t-case mate, on the left side of the trans..

I'm gonna try to see what they are if I can find out.there's also a sensor on the rear diff, 12 o'clock position (VSS?)

7/26/12rear diff sensor = speed sensor (speedo, etc.)left-center sensor = NSSleft-center-top = Solenoid controllerleft-rear sensor = Output shaft sensor

I replaced the OSS today, no change. I'll be ordering the governor solenoid and governor pressure sensor in the next few days. HOPEFULLY that will fix it, or at least, make it a lot better.

7/28/12Monday, I'll be ordering a HD governor solenoid and pressure sensor.. It'll take a few days for them to get here, so I'll update this once they arrive and are installed.

8/2/12Well, I broke down this morning and took it to a transmission shop to get a diagnostics test ran on the trans. I'll let you know what the result(s) is/are, as soon as I hear back.

8/3/12Diags was that the pcm was programmed with an unknown vin. So a complete test could not be done. Preliminary testing did point to the transducer though.

So here I go...Diags were $30. Parts are in. I took s few videos of the process as I went through it. The only issue I had was removing the sensor it had a clip that I did not see. I keep getting the output shaft speed sensor error but I've replaced it so I don't know what the problem is. He said when he ran diagnostics he could see the output shaft speed sensor work all the time. So whatever is causing that code must be intermittent.

Mental note: remember and I repeat remember to replace the transmission pan magnet when you clean it. I had to drop the pan a second time to put the magnet back in because my stupid brain forgot.

Here, you can see how much bigger the heavy duty solenoid is versus the stock oe unit. The pressure sensors are identical.

Ok I've been road testing it and checking/filling fluid level of trans. So far so good (other than the OSS code P0720), and it took right at 7 qts .Wish me luck. Now I need a clock spring for the srs/cc to work.. and kinda need the srs light to go out for state inspection pass.

8/20/12update:

trans still going strong!

9/24/12Update:

So, I towed all weekend..

This morning, before work, I went out to disconnect the trailer.

Walking out into the street, I noticed this trail of big drops of fluid down the street.. Following them visually, they went straight into my driveway (where I was backed in, yesterday) to a big puddly wet spot.. I then looked under the truck on the street and BAM! Big puddle.. Went to unhook the trailer and noticed the front of the trailer, the tongue, chains, and back of the truck were all covered in trans fluid (initial inspection.)

I made a couple trips/deliveries, one being 118mi round trip.

Sunday morning, I checked the hitch, chains, etc., before setting off and all was dry/dusty.

So something happened over the course of yesterday, in making a second 118mi round trip and a couple short local ones..

I'll have to get under there and clean everything off so I can see where it's coming from...
