Found a topic this morning in the 6.4 performance parts section that discussed this same thing. I had saw this same issue on my truck, but never thought it would be a learning curve. Here was the quote:

As far as the tranny revving then slamming into gear, Jeff also has posted to add 1/2 quart of tranny fluid, but before you do, crawl under and make sure no tranny leaks.
STOCK TCM
1. From a stop, accelerate the vehicle to 60 mph at approximately 1/2 throttle. DO THIS three times.
2. From a stop, accelerate the vehicle to 60 mph at wide open throttle. DO THIS three times.
SPARTAN TCM
1. From a stop, accelerate the vehicle to 55-60 mph at approximately 1/4 throttle. DO THIS TWICE.
2. From a stop, accelerate the vehicle to 65-70 mph at approximately 1/2 throttle. DO THIS TWICE.
3. From a stop, accelerate the vehicle to 70 mph at approximately 3/4 throttle. DO THIS TWICE.
4. From a 40 mph roll, press the accelerator to the floorboard quickly (forcing the truck to downshift) and accelerate to around 75 mph.
5. From a stop, acclerate to 75 mph at wide open throttle (press the accelator to the floor immediately). DO THIS 2-3 TIMES.
 Thanks for the help Jeff, just trying to make it easier for everyone to find. |
Also found this that Jeff from Spartan responded
"Load the tune. Once complete, take the truck for a drive. Drive through the gears easy a few times, stop sign to stop sign type driving (I live in a big neighborhood). I get out of the neighborhood, and make a 30 minute loop through the city/county I live in. We have a major U.S. highway and a major U.S. interstate running through here, so I have plenty of road to choose from. When I get to a red light or a stop sign, I run the truck at 1/2-3/4 throttle through the gears once I start going again. I do this as much as possible. The more 3/4 throttle pulls through the gears, the better. If you do enough, there really is no need for any full throttle pulls. I then get out on the interstate, going through the gears pretty hard up the on ramp. Before I merge on the interstate, I slow down to about 50-55 MPH and roll into the throttle hard. This allows for a good solid downshift and then a final shift in to OD with the converter locked. I try to imitate several different transmission shift patterns that I experience or use on a daily basis. I try to imitate them more than once.....actually as much as I can. The more you do, the better. After about 30 minutes, I am back in the neighborhood going through the stop signs again, easing through the gears. Everything shifts great from there.
It's ideal to do a relearn pretty often. After a few weeks on a tune (if you don't change very often), the shifts can get sloppy. To combat this, all you need to do is a quick relearn. No need in reloading the tune."
