With those codes on simaltaneously, I'd check the main harness AND fuse to the trans main power (for kicks and giggles).

 

I was thinking about this some more and I think you might have reinstalled the bolts in the wrong places. There are three different length bolts on that valve body and if you use a long one on the wrong place it can protrude all the way through. Double-check those bolts.

 

I checked the fuses and all are good...the three longer bolts went in the right spot on the valve body, I made sure that all bolts when into the right spots...Maybe I missed it and installed them wrong but I don't think I did. I also cleared the codes and then put the gear slector into drive position, soon as I did that all four codes came right back...

 

Pull the main harness, and put a voltmeter on the 12V pin to ensure you're actually getting voltage. then, you can be CERTAIN that lack of incoming power is NOT an issue. Mechanical problems should not give you those codes simultaneously. I'm willing to bet power to the trans is your TRUE issue.

 

I Found It And Fixed It........

All day at work I was thinking that I have got to have no power to the harness for all these codes to be active..So I went back out and checked the fuses again, ALL the fuses this time and there it was the 10 amp fuse labeled "IGN O" was blown...I quikly replaced the fuse and started my truck and to my surprise...It works and man does if shift like a dream. I went for a 30 min. drive and tested it at all speeds and every gear works as it should. I don't know how I poped this fuse but boy I'm happy that this is all it was.

Thanks for all your help guys, I knew I could get some good advice here..

 

glad i was wrong

 

Congrats on finding the problem.

 

Here is a post that I was working on yesterday before this issue was resolved. The photos that were taken here are of a unit that I was freshening up for a member here. Please excuse the used solenoids and harness. We use new in all our rebuilts.


With the transgo HD-2 kit it will lock the gear train in manual low when the trans is in limp mode. I have proven this on our Axiline dyno numerous times. I will post a video when I get a chance to upload it. I know that you guy's do not use the hd-2 kit. With this kit it gives you the gear command feature. In manual low, the low clutches will be applied along with 3-4 clutch while in limp mode. This is why the trans locks the gear train in manual low. There is no doubt in my mind that the customer has an electrical issue here. Could there be a cross leak...yes. But the solenoid codes are the first thing to address due to the fact that it has third gear starts and binds in manual low. I did suggest making sure that there is power at the trans. Go do some testing with the ASTRO dyno using the full hd-2 kit and maybe you will learn something here. You are just confusing this member. As far as installing the accumulator housing before the valve body causing a misalignment of the gaskets, you are totally wrong here. I do this on every unit that I personally build. There are two holes I used for alignment purposes that I believe the transgo kit clearly states to use them. Transgo makes reference to these on page 4 and they ID them by calling them the Z holes. Here is the picture of the case with these holes marked with a red marker.

I install these two bolts first to get the spacer plate and gaskets aligned using grease to stick the gaskets to the plate. Here is the Photo.

Then I install the the spacer plate support with the three bolts in the rear of the case along with the 1-2 accumulator housing. Here is the photo.

Then torque the bolts to 8ftlbs. Here is the photo.

ATSG (Automatic Transmission Service Group)recommends using this same procedure and then install the valve body after cleaning. Then I will remove the two alignment bolts and install the valve body.

Making sure to install the two alignment bolts first, along with the three bolts that have 8mm heads in the correct position that are 8mm long.

These are the ones if they are in the wrong position will lock the gear train. On page 5 of he transgo directions it clearly states where all the bolt should be when the directions are followed correctly. Here is a picture of the different length bolts.

Picture of all bolts placed in the proper positions.

And also don't remember to do this.


The end result is this member had a power issue to the trans. As I stated in manual low if the trans does not have power it will lock the gear train with this kit. Glad to see that it was a simple fix as we were hoping. I will post a video of the test that I have performed on the Dyno when I get a chance to upload it. Enjoy the photos. Vince

 

Good wright up Vince, I knew that I installed the accumulator housing, separator plate and valve boby correctly. These are some very good reference pictures for other members here that are doing the hd-2 install. Your the man...

 

Glad you liked it. I will be putting together a shift kit thread in the next couple weeks. This will help a lot of you I'm sure. Just takes time to gather the photo's and reference material. Vince
