I know there are a lot of trans threads going on... but it seems like everyone is having shuttle shift issues. I definitely don't have that. My issue is that it's not shifting from 2-3. It was just happening when the trans was cold, now it's happening randomly. I can sometimes shift to N and back to D quick and it'll go to 3rd. When it does shift, it slams into gear. Whenever I accelerate normally, it will hold 2nd until 2300 RPM and then slam to 3rd. If I get on it, the shifts are actually perfect. Much smoother and exactly the right points. What the crap! I adjusted the bands, didn't help. I see threads about TV cable.. and I don't know what that is or how to check it. Any ideas?
I took it to a local trans shop today, and I wasn't impressed. They didn't really have any thoughts other than put it on their diagnostic machine, but they didn't think it would show anything. I also asked if they did any upgraded transmissions, and they said "No, these Dodge transmissions get expensive". No crap.. I didn't say I didn't want to pay for it LOL. If you know any good shops in Northern IN I'd be interested in that too!
You don't have a TV cable, you have a TTVA motor. The only way to mess with its settings is using a shift enhancer or advancing the gear drive.
That doesn't sound like your problem any way. You would need to run pressure test to tell but it sounds like your gov pressure may be sticking high. Evidently the trans shop you went to is not up on current diagnostic procedures.
If you haven't done it, change out the gov pressure solenoid and transducer, and, while your at it an output speed sensor might be the problem. They all control, along with wheel speed, how the transmissions shifts 1-2 and 2-3. A problem in one can throw glitches all the way thru.
I'm havging the dame issue with 07. I have a billet goerend with a DTT shift enhacer. My probelm is it didn't do until I loaded my smarty. I was wondering if it has to do with torque mang or just part of the tune? I'm going to get a hold to DTT and ask if they have an answer for the issue.
If you reduced the TQ management then yes that is the likely problem. I am currently Smarty TNT SW1 with TQ 3, upgraded GM comversion solenoid, lower stall TC, TranGo SK, and a DTT Shift Enhaser. On settings 1 and light footing it shuttle shift is rare, like almost never.
Since you have about all the good pieces there are, a DTT Shift Enhanser set for your build might be a good investment.
I'm just having problems with the 2-3 shift when i'm just driving slow around town. It will hang in second gear until about 2000 RPM. It just sucks when your trying to pick up a little extra milage. It even says in the smarty manual somewhere that you will have to let off for a while for it up shift sometimes. But even under moderate to low throttle it shifts perfect. I was just hoping I could fix it with the DTT shift enhancer.

let me know what you find out. That sounds similiar to mine, except mine doesn't matter where the programmer is set or even if it's on. Mine also waits until about 2300 rpm to shift, even higher than yours. It's funny though, even if i let off the gas it won't shift. If I punch it, then it shifts. I might just try the parts Cerberusiam suggested. For $100 it's probably worth a shot.
