stalling, and torque converter locking/unlocking

[Seneca]

Weird Issues, Took The Marauder To Tennessee for vacation, almost 600 miles each way, after about 450 miles down the road at the start of the trip with cruise set at 70mph you could feel the T/C unlock and lock pretty violently it would do this ever so often, then when i got into town i had to two foot it most of the time to keep it running, when coming to a stop it wanted to stall. not everytime. 80% of the time though. it did this on the trip home too. It was very hot over 100. trans fluids not burnt. I change it once a year 5k miles at most! things replaced in the last 10k miles EGR/IAC/COPs/Plugs/ So what do you guys think? Almost seems like it could be a tune issue? I did reload my tune with no change. car just turned over 70k miles Regards Seneca

So it's been while, I've been driving the car around town a bit did some data logging. No driveability issues at all. I cleaned the MAF changed the coolant and took it on another long trip upstate NY this time. Ran really good! i think the MAF may have been a little dirty thanks to the lovely K/N air filter. Anyways I have a it narrowed down to this. It still stalls when coming to a stop, but only if the temp on my car show over 97 degrees outside... Really odd. I data logged and checked IATs Coolant temp battery Voltage Maf voltage. Nothing seemed to change at all. IAT's were at 112-130 depending on how fast i was going. coolant went as high as 198. this is a weird issue as soon as my cars outside temp went below 97 it ran great..

Do you have an aftermarket cooler? Highway + 4.10's = hot trans with no cooler.
