problems with Jet performance module

I have a 99 Dodge Ram 2500 pick up. Gas 2WD 360 V8 with 63000 miles. I installed a Jet Performance Module and immediately experienced a check engine light. I didn't drive it until I unplugged the battery (neg) lead for a few hours and then drove it. Once the truck was good and warm it wouldn't shift into overdirve. I changed the tranny fluid and filter and tried it again with the same results. I took it to a qualified mechanic who found a broken spring in the shift kit, a bad governor solenoid and a bad fluid pressure solenoid. The shift kit and solenoids were replaced, but it did have trouble again the next day. I took it back and the mechanic found that the factory solenoids were defective so he replaced them with higher quality after market replacements and it still has problems. I'm trying to find out if anyone else has experienced a similar problem. From what a transmission mechanic told me, he has seen this problem with the Jet module in another Dodge truck, but he couldn't remember what the result was. Thanks in advance.
