2 or 4 whl?

 

Over loading in o/d. Valvebody wear. Overheating. Many variables. Its tough to say why it failed a certain way.

Your probably talking about drilling the lube holes in the intermediate shaft. Gil younger does that in his kits. I have never done it.

As far as the lines, they make the old style fittings that replace them, pretty sure they are NPT, but the fittings need to be flared a certain way, just any ol fitting may crack the case.

The potentiometer will give you control over how late or early o/d comes in. Since throttle position is what tells the computer when to command o/d, and when not to. I dont know if you can run a set up like that on a 96 and up, the TPS does much more on the late model trucks.

 

I read all the 43 pages and i think i found the solution to one of my problems.
the first one is that my tranny is not shifting out of second gear till i let go of the gas pedal the solution i found in page 9 or 10 was to replace the governor solenoid. right??
or should i try cleaning it first??

the second problem happens when is cold out and i put in reverse the tranny will make a loud whiny noise.. i read somewhere that it was high pressure but it only happens when the truck is not warmed up
thanks in advance..

 

1998 4WD 2500, 5.9 V8, 46re, Thanks Monte.

 

Very rare, but it could be a leak into the transfer case.

 

Yeah, i would clean the solenoid first and see if that helps.

Fluid is much more viscous when its cold, which would make the noise more present. i wouldnt worry too much about the noise unless you start having problems.

 

Thanks for being available for questions!

I'm not nearly as adventurous as many on this thread that will disassemble their tranny, but maybe you can help me with two questions: what's wrong with my transmission and did I cause it?

I've got a 2001 1500, 5.9L, 46re tranny, 4WD, 108,000 miles

First, what's wrong: After towing a trailer for about 1000 miles, I had no problems until I started the truck the next day after I returned home. The check engine light came on (don't know the code yet since I'm 30 miles from anywhere!) but two things told me I had a tranny problem. All of this is intermittent. When I select drive, and go to accelerate, it's sluggish at best and at worst it's bucks while attempting to accelerate. When it is acting up, I don't feel like I could ever get any speed. At it's worst, it feels like it is about to lock up. The other problem that says I have a tranny problem is the noise coming from the tranny. It's like gears not meshing. Loud but dull sounding like the gears were made of aluminum. Both of these conditions do not seem related. The noise may be there at the same time as the acceleration problem or may not. It is not there when in park. The only thing that I have found to fix it so it is driveable is to put it in park and shut the engine off for a few seconds and turn it back on. Can you tell anything from my description? The local tranny shop told me by phone that it may be that some bronze shims may have disintegrated and fowled everything in the tranny.......whether that's close or not, I don't know but will cost some $2500 to rebuild. Can you add anything?

My second question is, did I do this? My truck GVWR is 6600 lbs and my GCWR is 12500, and max trailer weight is 7150 lbs. I'm pulling a trailer with GVWR of 4780 and with an ATV weighing about 500 lbs in the bed. It seems to me I'm well within the specs, but even so, is this too much to expect without problems? Reading some of the comments in this tread seems to maybe indicate so. If I get it fixed without your recommended upgrades, will it happen again? Can I expect a standard tranny shop to do any upgrades like you recommend?

Thanks again for your effort.

 

Well I've had it on the road for about 200 miles (mostly highway) after cleaning the solenoids. Most of the time it doesn't want to shift into overdrive. At 70 mph I let off the gas and the rpms drop down to 1500 but when I give it a little gas, it's back up to 3000.
Am I doing any further damage buy continuing to drive it?
Should I replace the overdrive solenoid to get a little more life out of it?
If there some kind of flush you recommend to run through the system to get rid of all the sludge or is it a case of once the clutches start burning, there's no stopping it?
Should I just bit the bullet and start the rebuild?
Thanks

 

I'm no expert but sludge in the tranny sounds BAD

 

Yeah. I towed a really heavy boat 1200 miles with 176K miles on the original transmission. Monte says the black sludge is from the fiber clutch plates, gray is from steel.
