Another trans dead
I didn't have a chance to get it scanned today, maybe tomorrow.
I haven't pulled the pan yet either. But, the fluid smells ok.
Could it be a solenoid? Or, would i still have 4th?

You cannot get 4Th without 3RD its a combo of the 3-4 clutch and the 2-4 band

I got my built one put in and had a fluke hard part failure after approx 130 miles of pretty easy break in driving.
I got a replacement and everything seemed good for a couple hundred miles until I lost compression in the engine do to cracked piston ring lands. (the guy who had it before me was apparently hammering it hard with bad tunes) I had it down for close to two months freshening up my forged bottom end. Then a little over 500 miles into my engine break in (very easy driving) I just all of a sudden lost 3-4 on the replacement tranny with no signs leading up to it at all. I actually checked the shifter location like three times to make sure I wasn't in neutral, because I couldn't believe it.
So now I'm to the point where I'm scared to even drive the car for fear of something going out. I have actually removed the procharger and just put on a cold air intake and will most likely sell the car soon. Seems like this car wasn't meant to be.

Seriously, if its not your daily driver and you just want to drive it and have fun put a TH400 in it and be done.

Sadly it is my DD. Or at least that was the plan. Otherwise that would be a great swap.
I still haven't had a chance to mess with the truck yet. Maybe after work today.
Well its kinda working blind but hey if that all you can do would you like me to send you some?

OK, I have an update. I used HPT to command the gears(Ididn't know HPT would do it).
Anyway Command at speed 45mph 1st good, 2nd good, 3rd -No change, Feels like second, 4th feels like it falls into neutral.
From a Stop if I command 3rd it stays in second. If I command 4th It goes back to 1st.

Verdad Gallardo ok try this unplug the harness and see what gear it feels like. those are some strange symptoms from a mechanical standpoint.

You mean it only has one gear. with the harness unpluged it should feel like second or third , Its really third . Which is a good thing since that means the 3-4 clutch is in tact other wise you would be in first. Basically you ceated limp mode, Which is max line and third gear only , Since you have a level 3 however do not attempt to manual shift to first with the plug unhooked as this can damage the 3-4 clutch.With the syptoms you have described and the clean fluild etc , I would have to lean heavily towads some electrical fault Im gonna go with shift solenoid B (2-3)maybe but we will send you both solenoids and the 3-2 just to be safe along with a pan gaskets. Please send your address to my email . Thanks

well you have to keep in mind you have no lockup with it unplugged so the rpm will be higher. With that plug unhooked there are only two possibilites for a gear , If the 3-4 clucth in bad you would be in first since 3rd without and 3-4 clutch pack make first. All thats on in third gear is the 3-4 clutch and the forward. In first all you have is the forward clutch so its one of two gears that are possible 1st or 3rd.

OK, I pulled the pan, and it is clean. So, I pulled the solenoids. The Piston on solenoid B feels stuck. The other solenoids piston moves freely and you can feel the spring behind it. Does that help?
The one that you can feel the spring is the 1-2 shift valve. The other is the 2-3 shift valve and it does not use a spring. I would check with Frank but you can probably put it back together and see if it works now.
Man, Im impressed with the two sponsors here that are both helping this guy. Kudos to Performabuilt and FLT! Way to go guys. Hope you get this guys issues resolved.

OK, I'll throw in my old set of solenoids out of my original trans and see if the make a difference. Thanks for all the help!
Does it sound like a solenoid problem? I guess I'll know if the old ones work.
Hmm but you have no way of actually looking at the data stream with the hptuner? to the the section that says actual gear?
