Yeah, if Dodge had built one we'd have saved the $15,000 this nightmare of a project has so far cost. I got screwed over early on, the project was simple. The Ex is just a 137" wheelbase.
My 4R100 transmission went out when i was still driving with the PSD. BTS transmissions are usually about $4,000. Matt Heady can build one far cheaper. At BTS i left paying over $5,000. 00. Very expensive. Long story, but i had to have a completely new transmission, got nothing on the core because my case was cracked. Also bought the upgraded 6. 0 transmission cooler, fluids, new computer chip, dyno runs, etc.
Does my transmission shift exactly the way i want it to? No. I will likely have the PCM reflashed once i have tuned the engine. I will likely hook up my boost gauge through the Ford MAP sensor to provide it with a load input as well.
Transmission shifts at exactly the same speed every time right now. Its OK because i had learned to shift manually like the BTS guys do. Its what they recommend and how they drive. A good driver will always have more control and be able to shift better than a computer. A reflash should make it shift however i want.
I would like more line pressure and faster shifts. It shifts way too smooth right now for my taste. No need to spend almost a grand on a controller. By the way, last time i checked it was cheaper to buy directly from PCS than ATS. Could be different now.
No driveshaft adjustments were needed. Just had to open the slots a little at the crossmember for it to slide back less than an inch. Quick and easy. The destroked.com kit is rated to over 1,000 hp to adapt your transmission. The flexplate is nearly 1/4" thick. It all goes together beautifully.
