SuperCharger to HEMI Transition?

The shop informed me that my automatic trans fluid is toasted at 47,000 miles most likely due to overheating. Not normal wear-and-tear. It appears that there's no metal shavings but a complete power flush and valve body service is now on the list for this build. This is my first real "sting" from the troubled transmission calibration caused by the supercharger. I suspect that there are only so many times you can downshift from 4th to 2nd at 75 mph before you overheat a modern automatic trans. If you can't calibrate in conjunction with factory torque management then don't mess around with it.

Body came off today.

I'm surprised the transmission isn't more damaged-- going from 4th or 5th at 75mph to 2nd isn't a transmission friendly act. That usually ends up with a lot damage being done. How, long did it stay in second gear at these speeds before it shifted again? This is one of the reasons why I hate the devil's handmaiden called the automatic gearbox. I hope this time you get the transmission tuned better-- your new engine might do serious damage to if that happens. You could easily roach it.

The shop is surprised too. And I'm not convinced there isn't some damage. We will see. The NAG-1 is good automatic gearbox. It's in lots of Chrysler and Mercedes Benz performance vehicles.

Some progress pics.

Might as well POR-15 a lot of the undercarriage while it is that state. Super cheap insurance against corrosion.

If I don't stop doing things tot truck I'm going to end up POR! It's a great idea. I thought about one of the undercarriage coatings. Not this time. When I go for Dynatrac axles next year I'll do the coating. Is POR-15 specific for our application?

Motor mounts in awaiting grinding/coating. Maybe I should see if they can use something special?
