I had Darrin from BCA Transmissions build me a custom valve body for my Expy transmission. I wasn't having any issues with my transmission, but the valve body I got from Darrin for my Crown Vic completely changed the performance of the car. It took almost 3 months for me to get time, but I finally got it installed.
I wasn't looking for something as dramatic with this one, a SUV is a different animal, but it did make a noticeable difference. After my first week with the body in, I've noticed the quicker shifts, especially under heavy acceleration. I no longer have a long lag when shifting from reverse into drive....that alway annoyed me.
I also always had a lag when it gets under 30 degrees and the Expy wasn't warmed up yet, almost like the tranny was slipping. I haven't noticed that either with the new VB.
I haven't towed anything with the new VB yet, but it should help with that as well. All in all, I think it was a good Mod. As soon as I get my belt slippage issue worked out, I will see exactly what it will do under full acceleration.
I went with Darrin because he does a version of the J-Mod on the VB, which is a modification of the plate as designed by the Ford engineer who designed the transmission and it uses OEM Ford parts. It's not a crappy "shift kit" that uses questionable parts.
