Ron,the trucks are not starting in 2nd,the transmission in my dad's has over 10K on it since I did the install,it is flawless,yes they both have the resistor. i have 6K on mine,with 4 storms plowing,if these trannys werent put together right,or were starting in 2nd,I would know it by now,and they would be fried by now. I have talked to Bill at DTT,and he made every effort to help me,even offered to send me DD2's. even though i got my DD3's from Nowel,I declined them. I think I may have stumbled on to my problem today,its still to early to tell yet. My edge comp was turning itself on,I called Edge,they sent me a new one,no questions asked,they have great customer service,I put it in today,no other changes,I just unplugged it,and plugged in the new one. Well the truck hasnt stalled all day,it hasnt even hinted at stalling,on an average day it would have stalled about 8 times today,with the driving i did. it used to almost cut out when dropping into gear,it doesnt do that at all now. I hope it stays this way. I cant explain why,I will call edge to find out if this makes any sense at all. Anyway with vendors like DTT,and Edge,Im not worried about it to much,they both have gone to any lenth needed to help dolve this problem,hopefully it is fixed now,I figure if its fine all week then its fixed. If i didnt get this new Comp,I would have never known. I mean this thing is rock steady now,going into gear,unblievable,i find myself gently going back ,and forth,laughing to myself,as it never hunts,and idles rock steady. My dad's truck is fine,once a month stalling is ok with him. he has more than enough power,he only wants more after he drives my truck,LOL. BTW Ron,Im an ex chrysler tech. Im not an expert on these trucks,by no means,but i know them pretty good now,and have a solid automotive background,16 yrs as mechanic. This has been a frustrating problem,one of the few ive had stump me this long. Thanks for your Help.
