At 16,500 miles I had my fluid and filter changed, bands adjusted, and a TransGo shift kit put in. I'd had no problem prior to the service and kit installation........it was just time for scheduled service and I wanted the kit for quicker/firmer shifts. I now have 24,800 miles on my truck. For the last 2,000 or so miles, if I did a full throttle run I started to experience a periodic delay (truck would fall off, no increase in rpms, then shift to the next gear, with the dealy being estimated at .2-.3 seconds) on my 1-2 and 2-3 shifts. Thanks to Dan Cragin the PCM variable is eliminated (sorta felt like bumping the rev limiter/problem much worse on drag radials). Dan also suggested I talk with the guy that does all the SRT10 transmission work for them. From that conversation I learned that they have a TransGo kit they use in California on the SRT10s that isn't the same that's available on the TransGo website or to my transmission guy. According to Joe at Westminster Transmissions, it's a larger box, is clearly marked "For Professional Installation Only", and contains among other additional parts a resistor that has to be soldered into a wire when the shift kit's installed to trick the tranny and computer to work together with the new increased pressures. My delays have temporarily gone away but I expect I'll get the resistor installed anyway. I only mention the above details because of the comment about installing a TransGo shift kit. As for the searching for the 1-2 shift, mine started doing the same under very light acceleration within the last week. This afternoon, per instructions on this forum I removed slack from the shift cable that attaches to the throttle linkage, and the problem's completely gone. That may be all that's required for yoru 1-2 shift search also.
