I've been lurking on this board for about 4 months now and have to say that the members of the TDR and the information that I got was what made me feel comfortable in buying my first CTD. The truck is a '98 QC 4X4 LB (12valve) with 100k on the clock that I happend to fall into for $15k. I am very happy with the truck so far... pulled my 27' TT for the first time a week or so ago. Very nice pulling truck. DC has to be kidding with this transmission though. I feel that half the power is lost there. I knew after reading this site that there were some answers to that problem and anything else that might come up. As for the first mod, a set of guages is in order, then who knows. Again, thanks for all the information.
