Okay, thanks.

I appreciate all the help everyone is giving, especially Mark. We go back racing next weekend so I'm going to datalog it and double check that it is locking. I'm pretty sure it is, I gained almost a tenth and a half. Any suggestions on which sensor might keep it from locking?

Yes with the switch on it does what I want. I realized what I posted before didn't make sense after I posted it. I've tried 2 different tuners with the same problem and multiple revisions.

I'm at the track today and it was still hitting the rev limiter on that one specific shift. I thought I had a buddy with access to ids but he doesn't. So I wired in a manual lock up switch and made a practice run, and it didn't hit the rev limiter on the 2-3 shift. But the tow haul light was...

Okay ill try that.

I've ohmed everything out and it all checks out. Is there a way to check that it is switching the ground? Or some other way to check it that I'm not aware of?

Okay, I guess ill try to figure out how to get that apart to check.

I know the third brakelight is out because it wouldn't fit with the rollcage and I've got the passenger side air bag out to for the cage and weight, but I'm not sure if any of that would have an affect.

Just to update this, I sent the converter in and had it checked, they found nothing wrong with it. It was definitely not locking, kind of at a loss of where to look now. Only thing I haven't checked electrically is the ground signal from the pcm.

Just to update, checked the harness last night and didn't find any rubs, checked the ground wire for the torque converter solenoid and it was fine. Got the pan off today and ohmed the solenoid and it checked fine. Checked the internal harness for continuity on both wires for the solenoid and...

Alright, thanks. Any suggestions on where to start looking? Don't know of much h about the technical side of these transmissions.

I'm having an ongoing issue with my race truck. I bought a used transmission and converter, trans is supposed to have 500 miles on a rebuild and about 1300 miles on the hard parts. Its continually hitting the rev limiter on the 2-3 shift. After multiple tune revisions last year it started...

I just took the ficm tune out of mine and it helped a good bit. Running the atlas economy tune it would run high egts and smoke pretty good on a heavy tow tune. Didn't really notice anything while idling on mine.

To give an update, I pressure tested it at work yesterday and did have a boost leak, not sure why I wanted to dismiss such an easy thing to do. I got the ficm tune out of it and it seems to have helped with both of those. Not sure when I'll get to pull anything with but when I do I'll try to...

I'll pressure test it this weekend and make sure. I'm working on getting the tune out of the ficm now. I've looked for exhaust leaks and didn't find any but I'll check again. For right now the turbo is staying.
