Oh, I must have missed that part.

 

☹️

Was really hoping someone would have some good ideas. Any idea how much a kit costs? Luckily I work at a place that sells parts and I can get a kit for like $300 USD. Never actually tackled this one before.

Just trying to figure out if I want to do it. I'm into this truck for like $2200 usd. It's a tough call for me. Or do I take one of the 727s we have laying around and rebuild it for $150 but no OD. This truck was mainly just supposed to be a tow rig for a race truck.

Decisions decisions.

 

Yep. Something ain't right there. You are either bleeding off pressure somewhere, or something else strange. You have reached the extent of my knowledge. To diagnose further would require a pressure gauge....... Any shop you take it to is just going to suggest a rebuild, whether it actually needs one or not.......

Now, that said, manual first is a different hydraulic circuit than computer controlled first gear. Manual first also applies one of the bands, where auto does not. But, no matter which way you slice it, this is a mechanical problem, not electronic.

 

Well I guess for the sake of one more filter and gasket I'll give it a try. If it's one last kick at the cat I'll drop the solenoid and sensor and bathe them in some cleaner, retorque the band's, and throw it back together. What's a $20 filter if I'm looking down the barrel of a $500 rebuild.

 

If your decide to rebuilt it there is a video series on YouTube dokie the 46RE and he shows talking it apart and putting it back together. The only special tool you need is a 30ton press for the overdrive unit, but that may not need replaced.

A local shop here is honest (they are small) and helped me out a few times. Maybe try to find one around you.

 

I've seen the sive of the press the guy uses in the video too, but I cant see that spring taking that much to compress. Is that size press necessary?

 

Some folks have done it with a bench vise, albeit, a BIG bench vise. The spring is 800 pounds per inch, so, compressing it one inch, you need 800 pounds pressure, compressing it 3 inches, you need 2400 pounds...... So, yeah, a press makes it easier..... but isn't absolutely required. (I have a 25 ton out in the garage that would work just fine, if anyone nearby requires one. )

 

Cool, I ask partly ask cause I have a rebuild in the future, and I know mine isn't a 30 ton off hand. Thinking its a 15 or 20.

 

That should work. Just need to make up the cool fixture so you can compress the spring, but still get in there with some tools.

 

I've seen the alignment and compression tool form sale as a set. Planning on doing that. The welded bolt system that guy uses is what made me realty question the amount of pressure needed. Doesn't look like the most stable thing in the world, even though they say the welds are stronger than the material itself
